The 74LVC1G00 provides the single 2-input NAND function.
Input can be driven from either 3.3 V or 5 V devices. These features allow the use of these devices in a mixed 3.3 V and 5 V environment.
Schmitt trigger action at all inputs makes the circuit tolerant for 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.
