74LVC1G34
SINGLE BUFFER GATE
Description
The 74LVC1G34 is a single buffer 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
OFF
. The I
OFF
circuitry disables the output preventing damaging current backflow
when the device is powered down.
The gate performs the positive Boolean function:

7. 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.
8. 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.
