DESCRIPTION

The 74AC20 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

including buffer output, which enables high noise

immunity and stable output.

All

inputs

and

outputs

are

equipped

with

protection circuits against static discharge, giving

them 2KV ESD immunity and transient excess

voltage.
