DESCRIPTION

The AC20 is an advanced high-speed CMOS

DUAL 4-INPUT NAND GATE fabricated with

sub-micron silicon gate and double-layer metal

wiring C

power

applications

mantaining

high

speed

operation similar to equivalent Bipolar Schottky

TTL.

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.
