The 74AUP1G158 is a single 2-input inverting multiplexer. Schmitt-trigger action at all inputs makes the circuit tolerant of slower input rise and fall times. This device ensures very low static and dynamic power consumption across the entire VCCrange from 0.8 V to 3.6 V. This device is fully specified for partial power down applications using IOFF. The IOFFcircuitry disables the output, preventing the potentially damaging backflow current through the device when it is powered down.
