DESCRIPTION
The 74V2G32 is an advanced high-speed CMOS
DUAL 2-INPUT OR GATE fabricated with
sub-micron silicon gate and double-layer metal
wiring C
2
MOS technology.
The internal circuit is composed of 3 stages
including buffer output, which provide high noise
immunity and stable output.

Power down protection is provided on all inputs
and outpu ts and 0 t o 7V can be accepted on
inputs with no regard to the supply voltage.
This device c an be used to interface 5V to 3V
systems and it is ideal for portable applications
like pers onal digital assistant, cam corder and all
battery-powered equipment.
All inputs and outputs are equipped with
protection circuits against static discharge, giving
them ESD immunity and transient e xcess voltage.
