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 C
2
MOS tecnology.
The internal circuit is composed of 3 stages
including buffer output, which enables high noise
immunity and stable output.
All
inputs
and
outputs
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
