The 74LVC1G04GW,125 is a Single Inverter. The 74LVC1G04 provides one inverting buffer. Input can be driven from either 3.3 or 5V devices. This feature allows the use of these devices in a mixed 3.3 and 5V environment. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall time. 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.
