74LVCE1G125
SINGLE BUFFER GATE WITH 3-STATE OUTPUT

Description

Pin Assignments(Top View)

The 74LVCE1G125 is a single non-inverting buffer/bus driverwith a 3-state output. The output enters a high impedancestate when a HIGH-level is applied to the output enable (OE)pin. The device is designed for operation with a power supply
range of 1.4V to 5.5V.

The inputs are tolerant to 5.5V

allowing this device to be used in a mixed voltage
