74LVC32A

QUADRUPLE 2-INPUT OR GATES

Description

The 74LVC32A provides four independent 2-input OR gates.

The

device is designed for operation with a power supply range of 1.65V

to 3.6V. 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 IOFF.

The IOFF circuitry

disables the output preventing damaging current backflow when the

device is powered down.

The gates perform the positive Boolean function:
