74HC14; 74HCT14
Hex inverting Schmitt trigger
Rev. 6 — 19 September 2012
Product data sheet
1. General description
The 74HC14; 74HCT14 is a high-speed Si-gate CMOS device and is pin compatible with
Low-power Schottky TTL (LSTTL). It is specified in compliance with JEDEC standard
No. 7A.
The 74HC14; 74HCT14 provides six inverting buffers with Schmitt-trigger action. It is
capable of transforming slowly changing input signals into sharply defined, jitter-free
output signals.
2. Features and benefits
Low-power dissipation
ESD protection:
HBM JESD22-A114F exceeds 2000 V
MM JESD22-A115-A exceeds 200 V
Multiple package options
Specified from 40 C to +85 C and from 40 C to +125 C
3. Applications
Wave and pulse shapers
Astable multivibrators
Monostable multivibrators
