General 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.

Features

Applications:

Wave and pulse shapers
Astable multivibrators
Monostable multivibrators.

Complies with JEDEC standard no. 7A
ESD protection:

Specified from -40 to +85 Cel and -40 to +125 Cel.
