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 IOFF. The IOFF circuitry
disables the output preventing damaging current backflow when the
device is powered down.
The gate performs the positive Boolean function:
AY
Features

Notes: 6. Stresses beyond the absolute maximum may result in immediate failure or reduced reliability. These are stress values and device operation should be
within recommend values.
7. Forcing the maximum allowed voltage could cause a condition exceeding the maximum current or conversely forcing the maximum current could cause a
condition exceeding the maximum voltage. The ratings of both current and voltage must be maintained within the controlled range.
