74AUP1T02GWH

Overview

The Nexperia 74AUP1T02GWH is a single 2-input NOR gate with voltage-level translator in a TSSOP5 (SOT353-1) package. It operates from a supply voltage of 2.3 V to 3.6 V, accepting inputs up to 3.6 V while functioning at lower logic levels. The device features Schmitt trigger inputs for noise immunity and slow signal tolerance. Static power consumption is low, with ICC reaching 1.5 μA maximum across the full temperature range. Propagation delay ranges from 0.5 ns to 11.9 ns depending on load capacitance and supply conditions.

Feature Summary

• Provides a single 2-input NOR function with integrated voltage-level translation capabilities.
• Schmitt trigger inputs ensure high noise immunity and tolerance for slower input rise and fall times.
• Includes IOFF circuitry to disable outputs during partial power-down, preventing damaging backflow currents.

Applications

• Logic-level translation between 1.8 V CMOS signals and 2.5 V or 3.3 V supplies
• Partial power-down applications requiring isolation of powered-down sections
• Battery-operated systems where operation must be maintained as voltage drops

Procurement Notes

Verify the ordering suffix 'H' against the manufacturer's current documentation to confirm specific reel or tape specifications. Ensure the TSSOP5 package variant matches the required footprint dimensions. Confirm RoHS compliance status directly with the supplier prior to finalizing procurement orders.

Selection Notes

Select this component when a single-channel NOR gate with level-shifting capability is required within the 2.3 V to 3.6 V range. The TSSOP5 package suits space-constrained designs needing surface-mount installation. Consider the propagation delay limits under specific load capacitances to ensure timing requirements are met.

Part Context

This device belongs to the 74AUP series of low-power CMOS logic ICs manufactured by Nexperia. The AUP family is characterized by wide supply voltage ranges and low static power consumption. The 74AUP1T02 specifically integrates voltage translation functions into a standard NOR gate configuration.

Replacement Considerations

Check for 74AUP1T02GW variants if the 'H' suffix denotes a specific packaging difference rather than a functional change. Verify pinout compatibility before substituting with other single NOR gates from the same logic family.

FAQ

Does the 74AUP1T02GWH support partial power-down mode?

Yes, the device includes IOFF circuitry that disables the output to prevent backflow current when the supply voltage is removed.

What is the maximum input voltage the device can tolerate?

The inputs accept voltages up to 3.6 V, allowing them to interface with higher voltage logic levels even when operating at lower supply voltages.
