74AUP1T14GXH

Overview

The Nexperia 74AUP1T14GXH is a low-power inverter with voltage-level translator housed in an X2SON5 (SOT1226-3) package. It operates within a supply voltage range of 2.3 V to 3.6 V and supports input voltages 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 limited to 1.2 μA at 25 °C and 3.5 μA at +125 °C. Propagation delay ranges from 0.5 ns to 11.9 ns depending on load capacitance and temperature.

Feature Summary

• Provides single-channel inverting logic function with Schmitt-trigger action for improved noise tolerance.
• Designed for voltage-level translation between 1.8 V CMOS signals and 2.5 V or 3.3 V supplies.
• Includes IOFF circuitry to disable outputs and prevent backflow current during partial power-down states.

Applications

• Logic-level translation in mixed-voltage digital systems
• Battery-powered devices requiring operation as voltage drops from 3.6 V to 2.3 V
• Partial power-down mode applications

Procurement Notes

Verify the specific ordering suffix 'H' against the manufacturer's official documentation to confirm packaging details, such as reel specifications or tape-and-reel quantities. Ensure the component version matches the required RoHS compliance standards and that the X2SON5 package dimensions align with the target PCB footprint constraints.

Selection Notes

Select this component when a single-channel inverter with voltage translation capabilities is required. The wide supply voltage range accommodates battery discharge profiles. Verify that the maximum propagation delay under expected load conditions meets system timing requirements and that the operating temperature range covers the intended environmental conditions.

Part Context

This part belongs to the 74AUP series of low-power CMOS logic devices manufactured by Nexperia. The 'GX' designation indicates the X2SON5 leadless package variant, while the 'H' suffix typically denotes a specific packaging configuration such as tape and reel. It is part of the broader portfolio of voltage translators and inverters designed for portable electronics.

Replacement Considerations

Direct replacements include other variants of the 74AUP1T14 family, such as the 74AUP1T14GW in a TSSOP5 package. Ensure any substitute maintains the same X2SON5 footprint if board space is constrained and verify that electrical characteristics like propagation delay and supply current remain compatible.
