The 74LVC1G125GW,125 is a non-inverting buffer/Line Driver with 3-state output. The 3-state output is controlled by the output enable input (OE). A high-level at pin OE causes the output to assume a high-impedance off-state. The input can be driven from either 3.3 or 5V devices. This feature allows the use of this device in a mixed 3.3 and 5V environment. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflow current through the device when it is powered down.
