74AUP1T02GXH

Overview

The Nexperia 74AUP1T02GXH is a low-power 2-input NOR gate with voltage-level translator in an X2SON5 package. It operates from a supply voltage of 2.3 V to 3.6 V and accepts inputs up to 3.6 V. The device features Schmitt trigger inputs for noise immunity and IOFF circuitry for partial power-down applications. Static supply current is typically 1.2 μA at 25 °C, rising to 3.5 μA at +125 °C. Propagation delay ranges from 4.7 ns to 11.9 ns depending on load capacitance and temperature.

Feature Summary

• Provides single 2-input NOR logic function with Schmitt trigger inputs
• Designed for logic-level translation accepting 1.8 V CMOS signals
• IOFF circuitry prevents damaging backflow current during power-down
• High noise immunity with low overshoot and undershoot

Applications

• Logic-level translation between 1.8 V and 3.3 V domains
• Partial power-down mode operation in battery-powered systems
• Battery-operated equipment requiring wide supply voltage range

Procurement Notes

Verify the specific ordering suffix GXH corresponds to the X2SON5 (SOT1226-3) leadless package variant. Confirm that the required temperature range matches the -40 °C to +125 °C specification provided in the datasheet. Ensure design compatibility with the 2.3 V to 3.6 V supply voltage limits and check if the IOFF functionality meets system power-down requirements.

Selection Notes

Select this component when a compact NOR gate with integrated voltage translation is needed. The X2SON5 package offers space savings compared to standard TSSOP options. Consider the propagation delay variations across the operating temperature range and load capacitance conditions. Verify that the input voltage tolerance aligns with the source signal levels.

Part Context

This part belongs to the 74AUP series of low-power CMOS logic devices manufactured by Nexperia. The AUP family is characterized by ultra-low power consumption and high speed. The 74AUP1T02 specifically integrates voltage translation capabilities within a NOR gate structure, distinguishing it from standard logic gates without translation features.

Replacement Considerations

The 74AUP1T02GW serves as a pin-compatible alternative using the TSSOP5 package. Both variants share identical electrical specifications and functionality. Selection depends primarily on PCB layout constraints and preferred mounting technology.
