DESCRIPTION

The ACT14 is an advanced high-speed CMOS

HEX

SCHMITT

INVERTER

fabricated

with

sub-micron silicon gate and double-layer metal

wiring C

2MOS technology. It is ideal for low

power

applications

mantaining

high

speed

operation similar to equivalent Bipolar Shottky

TTL.

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

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
