SN74AUP1T97YZPR

Translators, Level Shifters Overview

The SN74AUP1T97YZPR is a single-supply voltage-level translator from Texas Instruments, utilizing AUP technology for low-power applications. It operates within a supply voltage range of 2.3 V to 3.6 V and accepts input signals as low as 1.8 V LVCMOS. The device features nine configurable gate logic functions selectable via inputs A, B, and C. It includes Schmitt-trigger inputs with hysteresis (ΔVT = 210 mV) for noise immunity and supports partial-power-down mode with Ioff leakage current of 0.5 µA. Packaged in a 6-pin DSBGA (YZP), it provides optimized current drive of 4 mA.

Translators, Level Shifters Feature Summary

• Configurable Logic Functions: Supports up to nine distinct logic gate operations including AND, OR, NAND, NOR, MUX, Inverter, and Buffer by connecting control inputs to power or ground.
• Schmitt-Trigger Inputs: Provides enhanced noise rejection and signal integrity during switching transitions, accommodating slow input signal changes.
• Partial-Power-Down Support: Features an Ioff function that allows safe application of voltages up to 3.6 V on inputs/outputs when the device is unpowered, minimizing leakage.
• Optimized Drive Capability: Designed with 4 mA current-drive capability to reduce line reflections, overshoot, and undershoot.

Translators, Level Shifters Applications

• Logic-level translation between 1.8-V systems and 3.3-V or 2.5-V systems
• Portable and mobile equipment requiring low static and dynamic power consumption
• Analog mixed-mode designs benefiting from improved noise immunity

Translators, Level Shifters Procurement Notes

Verify the specific package marking code and moisture sensitivity level (MSL 1) against the latest TI Package Option Addendum. Confirm the YZP DSBGA footprint dimensions match your PCB layout requirements. Ensure ordering suffixes align with tape-and-reel specifications if high-volume manufacturing is intended.

Translators, Level Shifters Selection Notes

Select this component when a single-supply translator is required to interface 1.8-V logic with higher voltage domains like 2.5 V or 3.3 V. The configurable nature reduces bill-of-materials count by replacing multiple fixed-function gates. Consider the DSBGA package size constraints and thermal resistance characteristics for your enclosure design.

Translators, Level Shifters FAQ

How are the nine logic functions configured?

The logic function is determined by the logic levels applied to inputs A, B, and C. Connecting these pins to VCC or GND selects specific functions such as 2-to-1 MUX, AND, OR, NAND, NOR, Inverter, or Buffer.

What is the purpose of the Ioff feature?

Ioff allows the device to support partial-power-down mode. When VCC is 0 V, inputs and outputs can withstand voltages up to 3.6 V without damage, ensuring low leakage current in powered-down states.
