DESCRIPTION

The 74V2T32 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 ou tput, which provide high noise
immunity and stable output.

SOT23-8L 74V2T32STR

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 can be used to interface 5V to 3V
systems and it is ideal for port able applications
like personal digital assistant and all
battery-powered equipment.
All inputs and outputs are equipped with
protection circuits against static discharge, givi ng
them ESD immunity and transient e xcess voltage.
