The 74AUP1T97 is a configurable multiple function gate with level translating, Schmitt-trigger inputs. The device can be configured as any of the following logic functions MUX, AND, OR, NAND, NOR, inverter and buffer; using the 3-bit input. All inputs can be connected directly to VCCor GND. Low threshold Schmitt trigger inputs allow these devices to be driven by 1.8 V logic levels in 3.3 V applications. This device ensures very low static and dynamic power consumption across the entire VCCrange from 2.3 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.
