Diodes 74LV32A User Manual

A

Description

The 74LV32A provides provides four independent 2-input OR gates

with standard push-pull outputs. The device is designed for operation

with a power supply range of 2.0V to 5.5V.

The inputs are tolerant to 5.5V allowing this device to be used in a

mixed voltage environment. The device is fully specified for partial

power down applications using I

output preventing damaging current backflow when the device is

powered down.

The gates perform the Boolean function:

OFF

. The I

circuitry disables the
