IMPROVED LATCH-UP IMMUNITY

DESCRIPTION

The 74ACT14 is an advanced high-speed CMOS

HEX

SCHMITT

INVERTER

fabricated

with

sub-micron silicon gate and double-layer metal

The internal circuit is composed of 3 stages

including buffer output, which enables high noise

immunity and stable output.

The device is designed to interface directly High

Speed CMOS systems with TTL, NMOS and

CMOS output voltage levels.

This together with its schmitt trigger function

allows it to be used on line receivers with slow

rise/fall input signals.

All inputs and outputs are equipped with protec-

tion circuits against static discharge, giving them

2KV ESD immunity and transient excess voltage.
