SINGLE 2 INPUT POSITIVE OR GATE

Description

The 74LVC1G32 is a single 2-input positive OR gate with a
standard push-pull 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
disables the output preventing damaging current backflow
when the device is powered down.
The gate performs the positive Boolean function:

Y += or B
