74HC14D Hex inverting Schmitt trigger

The 74HC14D is a hex inverting schmitt trigger. The 74HC14D is a high-speed Si-gate CMOS device and are pin compatible with low power Schottky TTL (LSTTL). They are specified in compliance with JEDEC standard no. 7A. The 74HC14D provides six inverting buffers with Schmitt-trigger action. They are capable of transforming slowly changing input signals into sharply defined, jitter-free output signals.
