DESCRIPTION
The AC32 is an advanced high-speed CMOS
QUAD
2-INPUT OR GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology. It is ideal for low
power applications mantaining high speed
operation similar to equivalent Bipolar Schottky
TTL.
The internal circuit is composed of 2 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.
