? DESCRIPTION

The U74AUP1T57 provides low-power, low-voltage configurable

logic gate functions. The output state is determined by eight patterns

of 3-bit input. The user can choose the logic functions AND, OR,

NAND, NOR, XNOR, inverter and buffer. All inputs can be

connected to VCC or GND.

This device ensures a very low static and dynamic power

consumption across the entire VCC range from 2.3V to 3.6V.

The U74AUP1T57 is designed for logic-level translation

applications with input switching levels that accept 1.8 V low-voltage

CMOS signals, while operating from either a single 2.5V or 3.3V

supply voltage.

The wide VCC range of 2.3V to 3.6V allows the possibility of

battery voltage drop during system operation and ensures normal

operation between this range.

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.
