74VHC14; 74VHCT14

Hex inverting Schmitt trigger

The 74VHC14; 74VHCT14 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 74VHC14; 74VHCT14 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 and benefits

Balanced propagation delays
All inputs have Schmitt-trigger action
Inputs accept voltages higher than V_CC
Input levels:
- The 74VHC14 operates with CMOS input level
- The 74VHCT14 operates with TTL input level
ESD protection:
- HBM: ANSI/ESDA/JEDEC JS-001 class 2 exceeds 2000 V
- CDM: ANSI/ESDA/JEDEC JS-002 class C3 exceeds 1000 V
Multiple package options
Specified from -40 °C to +85 °C and from -40 °C to +125 °C
