74AUP1T32GXH

Overview

The Nexperia 74AUP1T32GXH is a single-channel, low-power 2-input OR gate with voltage-level translator. It operates within a supply voltage range of 2.3 V to 3.6 V and features Schmitt trigger inputs for noise immunity. The device supports partial power-down via IOFF circuitry and provides ESD protection exceeding 5000 V (HBM). Packaged in an X2SON5 (SOT1226-3) format measuring 0.8 x 0.8 mm, it functions across temperatures from -40 °C to +125 °C.

Feature Summary

• Provides logic-level translation accepting 1.8 V CMOS signals while operating at 2.5 V or 3.3 V supplies.
• Schmitt trigger inputs ensure tolerance to slow input rise and fall times.
• IOFF circuitry disables outputs during power-down to prevent damaging backflow currents.

Applications

• Logic-level translation between 1.8 V and 3.3 V domains
• Partial power-down applications requiring backflow current prevention
• Battery-operated systems utilizing wide supply voltage ranges

Procurement Notes

Verify the package suffix 'GX' corresponds to the X2SON5 (SOT1226-3) form factor. Confirm the temperature grade covers the required operational range up to +125 °C. Ensure compatibility with the specified 2.3 V to 3.6 V supply voltage limits for your target application environment.

Selection Notes

Select this component when a single-channel OR function with integrated level shifting is required. It is suitable for designs needing high noise immunity through Schmitt triggers and robust ESD protection. Consider the X2SON5 package for space-constrained PCB layouts requiring thermal enhancement.

Part Context

This part belongs to the 74AUP series of ultra-low-power CMOS logic devices. The '1T' designation indicates a single-transistor configuration optimized for voltage translation. The 'GX' suffix specifically identifies the leadless X2SON5 package variant manufactured by Nexperia.

Replacement Considerations

Direct substitutes include other 74AUP1T32 variants such as 74AUP1T32GW (TSSOP5 package). Verify pinout compatibility and package dimensions before substitution.

FAQ

Does the 74AUP1T32GXH support partial power-down?

Yes, the device includes IOFF circuitry that disables the output to prevent damaging backflow current when powered down.

What is the input voltage tolerance?

Inputs accept voltages up to 3.6 V, allowing them to interface with 1.8 V low-voltage CMOS signals even when the device operates at higher supply voltages.
