74AUP1T97FHX

Translators, Level Shifters Overview

The Fairchild Semiconductor 74AUP1T97FHX is a low-power configurable gate with voltage-level translator. It functions as a configurable multiple-function gate with level translating and Schmitt-trigger inputs, capable of implementing logic functions such as MUX, AND, OR, NAND, NOR, inverter, and buffer via a 3-bit input. The device operates within a supply voltage range of 2.3 V to 3.6 V. It features I_OFF circuitry for partial power-down applications, preventing backflow current. The component complies with JEDEC standards for various voltage ranges and offers ESD protection exceeding 5000 V (HBM) and 1000 V (CDM).

Translators, Level Shifters Feature Summary

• Configurable multiple-function gate supporting up to nine logic states including MUX, AND, OR, NAND, NOR, inverter, and buffer.
• Integrated voltage-level translation with low threshold Schmitt-trigger inputs enabling 1.8 V logic driving in 3.3 V applications.
• I_OFF circuitry enables partial power-down mode by disabling outputs to prevent damaging backflow currents.

Translators, Level Shifters Applications

• Voltage level translation between different logic families
• Partial power-down systems requiring backflow prevention
• Low-power portable and mobile device designs

Translators, Level Shifters Procurement Notes

Verify the manufacturer designation carefully, as the 74AUP1T97 series is widely produced by Nexperia and Texas Instruments under similar part numbers. Confirm that the specific FHX suffix corresponds to the intended MicroPak2-6 package and ensure the source document explicitly identifies Fairchild Semiconductor or its successor entity as the originator of this specific marking code to avoid cross-brand substitution errors.

Translators, Level Shifters Selection Notes

Select this component when design requirements demand a single IC to replace multiple discrete logic gates while simultaneously handling voltage level translation. The inclusion of Schmitt triggers makes it suitable for noisy environments or slow-rise signals. Ensure the application supports the 2.3 V to 3.6 V supply range and utilizes the configurable inputs to minimize board space and part count.

Translators, Level Shifters Part Context

This device belongs to the 74AUP family of TinyLogic devices, designed for universal, multifunction configurable logic in mobile and portable electronics. The AUP series is characterized by CMOS low power dissipation and high noise immunity. This specific model integrates level shifting capabilities, distinguishing it from standard logic gates by allowing direct interfacing between different voltage domains without external components.
