The 74AUP1G157 is a single 2-input multiplexer. Schmitt trigger action at all inputs makes the circuit tolerant to slower input rise and fall times. This device ensures a very low static and dynamic power consumption across the entire VCC range from 0.8 V to 3.6 V. 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.
