74LVC1G125Q
SINGLE BUFFER GATE WITH 3-STATE OUTPUT
Description
The 74LVC1G125Q is an automotive-compliant single, non-inverting
buffer/bus driver with a 3-state output. The output enters a high-
impedance state when a HIGH level is applied to the output enable
(OE) pin. 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.

4. Stresses beyond the absolute maximum can result in immediate failure or reduced reliability. These are stress values and device operation should be
within recommend values.
5. 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.
