What are the key features of CD74HC14MG4?
- Six independent Schmitt-trigger inverter channels provide hysteresis for reliable switching on slow or noisy input signals
- HC CMOS family supports 2 V to 6 V supply voltage, compatible with both 3.3 V and 5 V logic systems
- 14-pin SOIC tube packaging suits automated SMT assembly with industry-standard reel and tray options
What is CD74HC14MG4 used for?
CD74HC14MG4 is commonly used for signal conditioning on slow or noisy digital lines in embedded systems, industrial PLCs, and sensor interfaces. Its Schmitt-trigger hysteresis cleans up oscillating or degraded logic signals before they enter microcontroller GPIO pins, preventing false triggering. The device is also used in RC oscillator circuits and debounce networks where a sharp digital edge is needed from a slow analog waveform.

Frequently Asked Questions
How does the Schmitt-trigger hysteresis in CD74HC14MG4 improve signal integrity on slow-rise inputs?
Each inverter in CD74HC14MG4 has a built-in hysteresis window, typically 0.9 V at 5 V supply, so that signals must cross both a positive-going and negative-going threshold before the output toggles. This prevents multiple output transitions when a slow or noisy input crosses the switching point at less than 1 V per microsecond.
Can CD74HC14MG4 drive a 50 pF capacitive load at full specified speed, and what limits the toggle rate?
CD74HC14MG4 is characterized with a 50 pF load capacitance, which sets the propagation delay specification at nominally 7 ns at 5 V supply. Exceeding 50 pF per channel increases delay linearly, so driving longer PCB traces above 10 cm may require a series termination resistor to maintain signal integrity.
What RC oscillator frequency range can be built with CD74HC14MG4, and how is it calculated?
An RC oscillator using one inverter of CD74HC14MG4 generates frequencies from below 1 kHz up to approximately 10 MHz depending on the resistor and capacitor values. The oscillation period is approximately 1.4 times the RC time constant, so a 10 kΩ resistor and 1 nF capacitor yields roughly 71 kHz at 5 V supply.
