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.
device is powered down.
The gates perform the positive Boolean function:
The IOFF circuitry
disables the output preventing damaging current backflow when the
