DESCRIPTION
The 74HC14 and 74HCT14 are high-speed Si-gate CMOS
devices and are pin compatible with low power Schottky
TTL (LSTTL). They are specified in compliance with
JEDEC standard no. 7A.
The 74HC14 and 74HCT14 provide six inverting buffers
with Schmitt-trigger action. They are capable of
transforming slowly changing input signals into sharply
defined, jitter-free output signals.
