DUAL BUFFERS
Description
The 74LVC2G34 is a dual buffer gate with standard push-pull outputs.
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:
AY
