SN74HC14AN Hex Schmitt-Trigger Inverter IC – PDIP-14 – Texas Instruments

The SN74HC14AN from Texas Instruments is a high-performance hex Schmitt-trigger inverter designed for applications requiring clean signal transitions, waveform shaping, and reliable operation with slow or noisy input signals. Each of its six independent inverters features Schmitt-trigger input circuitry, providing superior noise immunity and stable logic switching.

With a wide 2V to 6V supply voltage range, the SN74HC14AN supports both low-voltage and standard CMOS logic systems. It delivers strong ±7.8mA output drive, making it suitable for a variety of digital and mixed-signal applications. Integrated positive and negative clamp diodes help protect inputs from voltage transients, ensuring long-term reliability.

Packaged in a standard PDIP-14 through-hole form factor, this device is easy to prototype and ideal for educational, industrial, and embedded electronic designs requiring robust signal conditioning.

Common applications include:
– Signal debouncing
– Waveform shaping
– Oscillator circuits
– Noise filtering
– Digital interfacing
