74LVC1G32
SINGLE 2 INPUT POSITIVE OR GATE
Description
The 74LVC1G32 is a single 2-input positive OR gate with a
standard totem pole output. The device is designed for
operation with a power supply range of 1.65V 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
