74AUP1G32GW,125

Overview

The Nexperia 74AUP1G32GW,125 is a single 2-input OR gate in the AUP logic family. It operates on a supply voltage range of 0.8 V to 3.6 V and features Schmitt-trigger inputs for noise immunity. The device utilizes CMOS technology for low power dissipation and includes IOFF circuitry for partial power-down applications. It is housed in a TSSOP5 (SOT353-1) package with five leads and supports an ambient temperature range from -40 °C to +125 °C.

Feature Summary

• Schmitt-trigger action at all inputs ensures tolerance of slower input rise and fall times.
• IOFF circuitry disables the output during partial power-down mode to prevent damaging backflow current.
• Overvoltage tolerant inputs allow operation up to 3.6 V even when the device is powered down.

Applications

• Partial power-down applications requiring protection against backflow current
• Digital signal processing circuits utilizing slow transition signals
• Low-power portable electronic devices operating within the 0.8 V to 3.6 V range

Procurement Notes

Verify that the ordering suffix matches the required package type, as the base part number covers multiple options. Confirm the specific temperature grade and lead finish requirements against the datasheet specifications before finalizing procurement orders to ensure compatibility with assembly processes.

Selection Notes

Select this component when a single 2-input OR function is required in a minimal footprint. The AUP series is suitable for designs needing wide voltage flexibility and high noise immunity. Ensure the application does not exceed the absolute maximum ratings for supply voltage or output current specified in the limiting values section.

Part Context

This component belongs to the Nexperia 74AUP1Gxx series of ultra-low-power logic gates. The 'GW' designation specifically identifies the TSSOP5 plastic thin shrink small outline package variant. It is part of a broader portfolio designed for battery-powered and space-constrained embedded systems.

Replacement Considerations

Direct replacements must match the 74AUP1G32 logic function and TSSOP5 package. Verify pinout compatibility and electrical characteristics against the original datasheet to ensure functional equivalence without redesigning the host circuit board.
