9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.

9.1 Application Information

The SN74AUP1G57 features configurable multiple functions. The output state is determined by eight patterns of 3-bit input. The user can choose the logic functions AND, NAND, NOR, XNOR, inverter, and noninverter. All inputs can be connected to VCC or GND.

This part can be used in any application where an equivalent single gate would work. The biggest benefit to this part is that it can be used for multiple functions on the same board, reducing the total number of part numbers to be used.

9.2 Typical Application

This application shows how the SN74AUP1G57 can be configured to work as an AND logic gate. This part can The capacitor shown is 0.1 uF and should be placed as close as possible to the part.

9.2.1 Design Requirements

This device uses CMOS technology and has balanced output drive. Take care to avoid bus contention because it can drive currents that would exceed maximum limits.

9.2.2 Detailed Design Procedure

  1. Recommended Input conditions
  2. Recommend output conditions
    • Load currents should not exceed 20 mA on the output and 50 mA total for the part
    • Outputs should not be pulled above VCC + 0.5 V.

9.2.3 Application Curve

The AUP family of single gate logic makes excellent translators for the new lower voltage microprocessors that typically are powered from 0.8 V to 1.2 V. They can drop the voltage of peripheral drivers and accessories that are still powered by 3.3 V to the new microcontroller power levels.
