DUAL BUFFER GATE WITH 3-STATE OUTPUTS
Description
Pin Assignments
The 74LVC2G125 is a dual buffer gate with 3-state outputs. The
device is designed for operation over a power supply range of 1.65V
to 5.5V. 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.

Notes:
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.
