74LV32A
QUADRUPLE 2-INPUT OR GATES
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
OFF
. The I
OFF
circuitry disables the
output preventing damaging current backflow when the device is
powered down.
The gates perform the Boolean function:
