IMPROVED LATCH-UP IMMUNITY
The internal circuit is composed of 2 stages
including buffer output, which enables high noise
immunity and stable output.
DESCRIPTION
The AC08 is an advanced high-speed CMOS
QUAD 2-INPUT AND GATE fabricated with
sub-micron silicon gate and double-layer metal
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
