U74AUP1T57 Datasheet
  

SINGLE-SUPPLY VOLTAGE-LEVEL TRANSLATOR WITH NINE

CONFIGURABLE GATE LOGIC FUNCTIONS

 

 

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 V CC or GND.

This device ensures a very low static and dynamic power

consumption across the entire V CC 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 V CC 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 I OFF . The I OFF circuitry disables the output, preventing the

damaging backflow current through the device when it is powered

down.

 

FEATURES

 

* Low power dissipation

* Wide supply voltage range from 2.3V to 3.6V

* Inputs accept voltages up to 3.6V

* I OFF supports partial-power-down mode
