74AUP1T32GWH

Overview

The Nexperia 74AUP1T32GWH is a low-power single-channel 2-input OR gate with voltage-level translation capabilities. It operates within a supply voltage range of 2.3 V to 3.6 V and supports input voltages up to 3.6 V, enabling the translation of 1.8 V CMOS signals to higher logic levels. The device features Schmitt trigger inputs for noise immunity and includes IOFF circuitry for partial power-down applications. It is housed in a TSSOP5 (SOT353-1) package and is specified for ambient temperatures ranging from -40 °C to +125 °C.

Feature Summary

• Provides a single 2-input OR function with integrated voltage-level translation for interfacing different logic families.
• Schmitt trigger inputs ensure tolerance to slower input rise and fall times across the entire operating voltage range.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents through the device.

Applications

• Logic-level translation between 1.8 V low-voltage CMOS signals and 2.5 V or 3.3 V supplies
• Partial power-down mode operation in battery-powered systems
• Noise-immune signal processing in environments with slow input transitions

Procurement Notes

Verify that the specific part number suffix matches the required package type, as the base model may be available in multiple packages such as X2SON. Confirm the temperature grade corresponds to the application's thermal requirements, specifically checking for the extended range specification if operating above standard industrial limits. Ensure the ordering code aligns with the desired reel or cut tape quantity specifications provided by the distributor.

Selection Notes

Select this component when a single-channel OR gate with voltage translation is required. It is suitable for designs needing to interface 1.8 V logic with 3.3 V domains without external level shifters. Consider the TSSOP5 package constraints regarding board space and thermal dissipation. Verify that the maximum propagation delay meets the timing requirements of the target system under the specific load capacitance conditions.

Part Context

This component belongs to the 74AUP series of low-power CMOS logic devices manufactured by Nexperia. The AUP series is characterized by wide supply voltage ranges and high noise immunity. The 74AUP1T32 variant specifically integrates voltage translation functionality into a standard OR gate configuration, distinguishing it from basic logic gates that lack this feature.

Replacement Considerations

Direct replacements include other variants within the 74AUP1T32 family, such as the 74AUP1T32GXH, which utilizes an X2SON package instead of TSSOP. Ensure any substitute maintains the same voltage translation capabilities and package footprint compatibility.
