SN74AUP1G02DSFR

Overview

The SN74AUP1G02DSFR is a low-power single 2-input positive-NOR gate from the Texas Instruments AUP logic family. It operates within a supply voltage range of 0.8 V to 3.6 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device features an ultra-small SON-6 package (DSF) measuring 1.45 mm by 1.00 mm. Key electrical parameters include a maximum propagation delay of 4.6 ns at 3.3 V, a typical input capacitance of 1.5 pF, and a maximum static current of 0.9 μA.

Feature Summary

• Supports live insertion and partial-power-down modes via integrated Ioff circuitry that prevents back-drive current when powered off.
• Provides enhanced switching-noise immunity through built-in input hysteresis suitable for slow input transitions.
• Delivers low noise performance by limiting overshoot and undershoot to less than 10% of VCC.
• Optimized for point-to-point applications with balanced output drive capabilities.

Applications

• Active Noise Cancellation (ANC)
• Embedded PC systems
• Software Defined Radio (SDR)
• HVAC control units

Procurement Notes

Verify the specific package suffix DSFR corresponds to the 6-pin SON configuration during procurement. Confirm RoHS compliance status and lead finish details against the latest manufacturer orderable addendum. Ensure the ordering quantity aligns with standard carrier sizes specified in the packaging information section of the datasheet.

Selection Notes

Select this component for designs requiring minimal board space due to its compact footprint. It is appropriate for battery-powered portable devices where low quiescent power consumption extends operational life. Consider its 3.6-V I/O tolerance for interfacing between different voltage domains without additional level shifting components.

Part Context

This part belongs to the SN74AUP1Gxx series of single-gate logic devices designed for ultra-low power applications. The AUP family utilizes advanced CMOS technology to achieve high speed while maintaining very low dynamic and static power dissipation across the entire operating voltage range.

FAQ

How does the Ioff feature function?

The Ioff circuitry disables the outputs to prevent damaging current backflow through the device when it is powered down, supporting live insertion and partial-power-down modes.

What is the purpose of the input hysteresis?

Input hysteresis allows for slower input transition rates and provides better switching-noise immunity at the input pins.
