74LVCE1G125

SINGLE BUFFER GATE WITH 3-STATE OUTPUT

Description

The 74LVCE1G125 is a 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 1.4V 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 output preventing damaging current backflow when the device is powered down.
