74LVC1G125GW Datasheet PDF - NXP

●General description

●The 74LVC1G125 provides one non-invertingbuffer/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 V or 5 V devices. This feature allows the use of this device in a mixed 3.3 V and 5 V environment. This device is fully specified for partial power-down applications using IOFF. The IOFF circuitry disables the output, preventing the damaging backflowcurrent through the device when it is powered down.
