DESCRIPTION

The 74ACT20 is an advanced high-speed CMOS

DUAL 4-INPUT NAND GATE fabricated with

sub-micron silicon gate and double-layer metal

wiring C2MOS tecnology.

The internal circuit is composed of 3 stages in-

cluding 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.

All inputs and outputs are equipped with protec-

tion circuits against static discharge, giving them

2KV ESD immunity and transient excess voltage.
