Overview
The 74HC14D/S400118, produced by NXP USA Inc., is a high-speed CMOS hex inverting Schmitt trigger. This device is fabricated using silicon gate C2MOS technology, which allows it to achieve high-speed operation similar to equivalent LSTTL while maintaining the low power dissipation characteristic of CMOS technology. The 74HC14D features six independent inverting Schmitt trigger circuits, each with a hysteresis voltage that helps in transforming slowly changing input signals into sharply defined, jitter-free output signals.
