DESCRIPTION
The 74LX1G32 is a low voltage C MOS SINGLE
2-INPUT OR GATE fabricated with sub-micron
silicon gate and double - layer metal wiring C

MOS
tecnology.
It is ideal for 1.65 to 5. 5 V
CC
operations and low
power and low noise applications. The internal
circuit is composed of 3 stages including buffer
output, which provide hi gh noise immunity and
stable output.
Powerdownprotectionisprovidedoninputand
output and 0 to 7V can be accepted on inputs with
no regard to the supply voltage. It c an be
interfaced to 5V signal environment for inputs in
mixed 3.3/5V system.
All inputs and outputs are equipped with
protection circuits against static discharge.
