One of the most universal chips is the Hex Schmitt Trigger, known as the 74C14. It is also marketed as 40106, 40014, and 74HC14. These are CMOS chips and are characterised by low current consumption, high input impedance and a supply voltage from 5v to 15v. (Do not substitute 7414 or  74LS14. They are TTL chips and operate on 4.5v to 5.5v and have low impedance inputs.)

Fig: 1 shows the six Schmitt gates in a 74c14 chip.

We will concentrate on the single-input Schmitt Trigger gate as contained in the 74c14 IC. 
Fig: 4 shows the Schmitt Trigger Characteristic:

The output is HIGH until the input rises to 66% of rail voltage. 
The output goes LOW when the input goes above 66%.
The output remains HIGH until the input fall to 33%. 

A Schmitt Trigger gate can be wired as an oscillator, delay, inverter (and other functions, depending on the surrounding components).

Each of the 6 gates in the 74c14 can be used to create a separate "building block" and this gives the chip a wide range of capabilities. 

THE FREQUENCY OF AN OSCILLATOR
When a capacitor and resistor are added to a Schmitt Trigger gate, as shown in the first circuit 
of Fig: 5 above, the result is an oscillator called a MULTIVIBRATOR. A multivibrator has the feature of producing a square wave and this waveshape can have equal high and low periods (called 50:50 mark:space ratio) or any ratio of high and low periods. The HIGH period is called the MARK and the LOW is called the SPACE
The frequency of an oscillator depends on the value of R and C. There is no fixed "ratio" for these components however it is best to refer to sample circuits to see the values needed for a particular frequency - otherwise you may arrive at "unusual" combinations such as very large capacitors and very small resistors to achieve a high frequency. 
The frequency of a Schmitt oscillator is determined by the following equation: 
    cuando los cerdos se mudan a casa pdf
An easier equation to work with is:
cuando los cerdos se mudan a casa pdf
Oscillator circuits for the 74c14 can be separated into three categories:
1. Low frequency
2. Medium frequency, and
3. High frequency
Low frequency oscillators are below 1Hz and can also be classified as DELAY circuits or TIMING circuits. 
Medium frequency oscillators range from 1Hz to about 500kHz. 
High frequency oscillators are above 500kHz. 
We separate circuits into three categories due to the value of capacitor needed. 
For low frequency oscillators the capacitor is an electrolytic, ranging from 1u to 220u.
For medium frequency circuits the capacitor is a ceramic 1n to 100n
For high frequency circuits the capacitor is a ceramic 47p to 1n
The value of R should be in the range 10k to 4M7 in all cases. 
The maximum frequency for a particular chip will depend on the supply voltage and the type of chip. 
Some chips do not like supply voltages below 5v (maximum supply voltage is 15v for all chips in this discussion) while other chips (HS) are especially made for high speed operation. All chips will operate up to 500kHz with a 5v to 12v supply. Requirements outside this range will need special investigation. Some chips are designed to operate down to 2-3v.

The Complete Guide to “Cuando los Cerdos se Mudan a Casa PDF”: Origins, Content, and Practical Applications

Capítulo 7: Cuando tú eres el cerdo (la autocrítica incómoda)

No todo es culpa de los otros. A veces, nosotros somos los cerdos que se mudan a casas ajenas. O a nuestra propia vida en forma de autosabotaje.

Pregúntate:

  • ¿He invadido el espacio emocional de alguien sin permiso?
  • ¿He normalizado mi propio desorden como "personalidad"?
  • ¿He exigido que otros se adapten a mis hábitos sin ceder nada?

La solución no es castigarte, sino reconocer que hasta el cerdo más obstinado puede aprender a vivir en su propia pocilga sin ensuciar la casa ajena.


Fase 1: La visita inocente

"Vengo solo a tomar un café". "Déjame ayudarte con esa mudanza". "Quédate con mis llaves por si acaso". El cerdo huele las grietas de tu vida.

When the Pigs Move Into the House

A modern fable

In a small village nestled between a forgotten orchard and a muddy river, there lived a farmer named Eladio. He was old, tired, and had long ago stopped arguing with the world. His house — a creaking, timber-framed cottage — had been in his family for three generations. And his pigs, a dozen stout, clever creatures with pink hides and sharp eyes, lived in a pen by the barn.

One wet spring, the river rose and washed away half the pig enclosure. Instead of rebuilding, Eladio shrugged and left the gate open. That night, the pigs — led by a particularly bold sow named Fantasma — discovered the back door of the house was loose. With a single push of her snout, she stepped into the kitchen.

By morning, the pigs had moved in.

Not violently. Not even noisily. They simply settled. They slept by the hearth, rooted through the pantry, and nudged Eladio for scraps while he ate his thin soup. At first, he laughed. “They won’t stay,” he told the baker. “They’re pigs. They belong in the mud.”

But the pigs did not leave.

They learned to turn the faucet with their teeth. They dragged blankets from the bedroom to make nests in the living room. Fantasma discovered how to open the refrigerator door by leaning against it. Within a month, the house smelled of wet earth, apples, and something sweetly rotting beneath the floorboards. cuando los cerdos se mudan a casa pdf

The neighbors were horrified. “You cannot live with pigs inside your house,” said Doña Clarisa from across the road. “They will destroy everything. They will make you sick. They will forget they are pigs.”

Eladio listened, nodded, and did nothing. The truth was, the pigs were better company than his own family had been. His wife had left him seven winters ago. His children had moved to the city and never wrote. The pigs snuffled softly when he spoke, pressed their warm sides against his legs at night, and never asked for explanations.

But the pigs did not stay pigs for long.

One evening, Eladio found Fantasma sitting in his armchair — upright, her hooves resting on the armrests, watching the television he had left on. Her eyes followed the images with a strange, deep attention. The next day, she was wearing his dead mother’s shawl. A week later, the other pigs began walking on their hind legs more often than on all fours.

They mimicked him. They learned to unlock doors, pour water into bowls, and sweep dust into corners (though never quite correctly). They began to speak — not in words, but in grunts that carried meaning, rhythm, intention. Eladio understood them perfectly. “More bread,” Fantasma grunted one morning. “No, the soft one. And turn up the heat. The floor is cold.”

Changes in the village followed. The pigs started visiting the neighbors, sitting on their porches like old men, accepting cups of tea with surprising delicacy. Children threw stones at first, but the pigs simply stared until the children ran away crying. The mayor called a meeting. “This is unnatural,” he said. “Either the pigs go back to the mud, or the people will leave.”

But the pigs had already learned to read. Fantasma found Eladio’s old law books and flipped through them with her snout. “The deed to this house,” she grunted one rainy afternoon, “names no species. Only ‘inhabitants.’ We are inhabitants.” She pointed a muddy hoof at the word. “You cannot evict us.”

Eladio laughed again — but quietly this time. Because he wasn’t sure if the pigs were joking.

Months passed. The pigs built an addition to the house with stolen lumber and remarkable teamwork. They established rules: no slaughter (obviously), no yelling, the best sleeping spots rotate every week, and any pig who roots up the garden floor must replant it. Fantasma became the spokesperson. She negotiated with the butcher (now converted to a bakery), the postman (who refused delivery), and the tax collector (who was too afraid to enter).

One morning, Eladio woke up and realized he no longer knew who lived in whose home. The pigs had taken the beds. He slept on a pile of hay they had dragged into the barn. His hands were rough, his nails long, his diet mostly turnips and fallen apples from the pigs’ leftovers. He grunted more often than he spoke. The Complete Guide to “Cuando los Cerdos se

Looking into the bathroom mirror, he saw a pig staring back — not in shape, but in expression: calm, acquisitive, slightly amused. He tried to speak. A low oink came out.

Doña Clarisa saw him that afternoon rooting through her garbage for potato peels. She crossed herself and called the priest. But the priest had already met with Fantasma. The pigs were planning a Christmas pageant. They had invited the bishop.

And that is when the rest of the village finally understood: the pigs had not moved into Eladio’s house. They had moved into the human condition. And Eladio — kind, tired, lost Eladio — had slowly, comfortably, become something else. Not a pig. Not quite a man. Something in between. A creature who remembered speaking but preferred mud.

The fable ends without a moral. Only a question: When the pigs move into the house, who is really leaving?

The story of the book Cuando los cerdos se mudan a casa When Pigs Move In

) is one of spiritual transformation and the battle against unseen forces. Written by Don Dickerman

, an ordained Southern Baptist minister with over 30 years of prison and deliverance ministry, the book serves as a practical guide for "sweeping clean" demonic influences from one's life. The Core Message

The title uses "pigs" as a metaphor for demonic spirits—drawing from the biblical story where Jesus cast a "Legion" of demons into a herd of swine. Dickerman’s central thesis is that these "pigs" can find "legal ground" to enter and inhabit a person's life through open "doors" like sin, generational curses, or trauma. Impactful Stories and Testimonies

A significant part of the book's narrative power comes from real-world accounts of deliverance. Dickerman shares testimonies from his ministry in high-security prisons and churches, including: Cuando los Cerdos se Mudan a Casa (When Pigs Move In) ¿He invadido el espacio emocional de alguien sin permiso

There is no famous bestseller with this exact Spanish title. However, the phrase is widely associated with a popular urban legend, a fable about boundaries, or a misremembered title of a famous self-help book.

Here is a breakdown of what this piece usually refers to, the likely book you are looking for, and a summary of the parable itself.

Each gate of a 74c14 is capable of delivering up to 20mA with a 12v supply, 15mA with a 9v supply and 10mA with a 5v supply. A buffer transistor can be used to increase the output current if needed. 
Fig: 7 shows how a buffer transistor is connected to the output of a gate:

cuando los cerdos se mudan a casa pdf

The voltage and current (called the "supply") for the 6 gates in a 74c14 comes from pin 14. The ground pin for the chip is pin 7. Each gate on a circuit diagram is normally shown without the power rails. It is understood they are present.
Fig: 8 shows the power rails for a 74c14 and the individual gates:

HOW A GATE WORKS
The next diagram (it is a repeat of Fig: 4 above) shows how the output of a Schmitt gate jumps from HIGH-to-LOW and LOW-to-HIGH as the input voltage rises and falls:

cuando los cerdos se mudan a casa pdf

The output of a Schmitt Trigger gate is the opposite of the input. When the input is LOW, the output is HIGH.
As the input rises to 66% of rail voltage, the output instantly goes LOW and the input has to fall to 33% of rail voltage for the output to go HIGH. 
The gap between 33% and 66% is called the HYSTERESIS GAP and this has been specially designed so that the input does not detect small fluctuations.

cuando los cerdos se mudan a casa pdf

Fig: 9 shows a voltage being applied to the Schmitt gate. The voltage is 55% of rail and this is not sufficient to change the output: 

cuando los cerdos se mudan a casa pdf

The following figure shows a normal gates. It changes when the input rises above about 53% of rail voltage and changes back when the input falls below 47%.

 cuando los cerdos se mudan a casa pdf 

The following diagram shows the very small gap for a normal chip, where the output jumps from HIGH-to-LOW in an uncontrolled manner:

 cuando los cerdos se mudan a casa pdf

Here's the secret of a Schmitt gate: Any noise (up to 60%) entering a Schmitt Trigger will not alter the condition of the gate. Any noise up to 55% entering a normal gate will change the output:

cuando los cerdos se mudan a casa pdf  cuando los cerdos se mudan a casa pdf

There is one other problem with a normal gate. When the input is in the range of about 47% to 53%, the output goes high/low very rapidly. This is called the INTERMEDIATE ZONE and the output does not know if it should be HIGH or LOW. 
Fig: 10 shows the input voltage varying in this intermediate zone and the output fluctuating very rapidly:

cuando los cerdos se mudan a casa pdf

Even a fixed voltage in the intermediate zone will cause the output to fluctuate:

cuando los cerdos se mudan a casa pdf

This is due to the high gain of the amplifier in the gate and it does not know if the output should be high or low.  It is essential for the input voltage to pass through this zone very quickly to prevent the gate "oscillating."
The output will only fluctuate when the input voltage is rising slowly or sits in the zone, as it takes a short period of time for the gate to start oscillating. 
For this reason a normal gate is not suitable for low frequency (slow-rising waveforms).
The Schmitt gate does not have this problem. 
If the voltage on the input of a Schmitt Trigger rises very slowly, the output changes at 66% and it will only change back to its original state when the voltage drops to 33% of rail voltage. At no time does the gate self-oscillate. This is one of the advantages of the Schmitt Trigger. 

Fig: 12 shows how a Schmitt gate can be considered to be similar to a common-emitter NPN transistor:

cuando los cerdos se mudan a casa pdf

The similarity is only approximate and you can see the general operation of each circuit has some similarities. It is important to note that the two circuits cannot be interchanged without modifying the surrounding components. 

SWITCH DEBOUNCE
A Schmitt gate can be used to eliminate noise from a switch.  When any type of mechanical switch is closed, the contacts "bounce" due to the dirt and an oxide coating on the contacts and this puts noise on the line. Sometimes this noise is seen as additional pulses by high-speed digital circuits with the result of "false-counting." The Schmitt gate circuit below prevents multiple pulses from being passed to a circuit:

SIGNAL CONDITIONING
The Schmitt Trigger can be used to improve the quality of a signal by speeding up the rise and fall times. The rise and fall time is called the TRANSITION TIME. The Schmitt trigger will reshape a waveform into a square wave. 
It will also convert a SINEWAVE or ANALOGUE waveform to a SQUAREWAVE. 
Any form of improving a signal to a square wave is called SIGNAL CONDITIONING
This is also called RISE-TIME improving. The Schmitt Trigger produces a fast-switching digital output suitable for edge triggering.
Fig: 14 shows waveforms improved by a Schmitt Trigger.  Only excursions above 66% will appear in the output:

cuando los cerdos se mudan a casa pdf

SWITCHING THRESHOLD 
The SWITCHING THRESHOLD is the point where a signal changes logic states. 
A Schmitt Trigger has two thresholds - or TRIP POINTS. A positive going threshold (Vt+) and a negative going threshold (Vt-). 
The positive going threshold is also called the UPPER THRESHOLD and occurs at 66% of rail voltage. The LOWER THRESHOLD occurs at 33% rail voltage. 
The difference between the two thresholds is called the HYSTERESIS ZONE.
A signal will not change the state of the gate until it passes the positive going threshold. A high signal that enters the Hysteresis Zone will not change the state of the gate until it reaches the negative going threshold.
Besides preventing unwanted oscillation, the Hysteresis Zone also provides noise immunity.

THE 4093 IC
Another common Schmitt Trigger IC is the 4093. This is a Quad 2-Input Schmitt Trigger.

cuando los cerdos se mudan a casa pdf

The CD 4093 is sometimes used for its gating capability. One of the inputs of the gate can used to turn the gate on and off.  This is called GATING. This feature can be achieved with a single-input Schmitt Trigger with a diode. This allows the 74c14 IC to be used. 
Fig: 16 shows how to substitute a 4093 NAND gate for a single-input gate:

SUBSTITUTING THE 555
The 555 can be replaced by the 74c15 in almost every case, with the advantage of lower quiescent current and the availability of 6 building blocks. The 74c14 Schmitt gate is comparable with the 7555 (the CMOS version of the 555).
Fig 17 shows a 10 MINUTE TIMER. The circuit is also called a DELAY circuit:

The 555 replaced by a Schmitt gate and a transistor to provide the drive-current:
cuando los cerdos se mudan a casa pdf


SUMMARY
A Schmitt Trigger is a bistable (two-state) device used to square-up waveforms with slow rise and fall times. The most common applications are THRESHOLD DETECTION and SIGNAL CONDITIONING. Speeding up the TRANSITION (rise and fall) time affects the shape of the waveform, turning poor signals into reliable waveforms capable of driving digital ICs.
The THRESHOLD DETECTION feature will prevent signals with insufficient amplitude (such as noise) from activating the clock lines of digital chips.
