DESCRIPTION

The 74LX1G32 is a low voltage CMOS SINGLE

2-INPUT OR GATE fabricated with sub-micron

silicon gate and double-layer metal wiring C MOS

technology.

It is ideal for 1.65 to 5.5 V

Power down protection is provided on input and

output and 0 to 7V can be accepted on inputs with

no regard to the supply voltage. It can be

interfaced to 5V signal environment for inputs in

mixed 3.3/5V system.

operations and low

power and low noise applications. The internal

circuit is composed of 3 stages including buffer

All inputs and outputs are equipped with

protection circuits against static discharge.
