■
■
■
The internal circuit is composed of 2 stages
including buffer output, which provide high noise
immunity and stable output.
Power down protection is provided on all inputs
and 0 to 7V can be accepted on inputs with no
regard to the supply voltage. This device can be
used to interface5V to 3V.

IMPROVED LATCH-UP IMMUNITY
LOWNOISE:VOLP = 0.8V(Max.)
DESCRIPTION
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them 2KV ESD immunity and transient excess
voltage.
The 74VHC32 is an advanced high-speed CMOS
QUAD 2-INPUT OR GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C2MOS technology.
