SN74AUP1G00DSF2

Overview

The SN74AUP1G00DSF2 is a single 2-input positive-NAND gate from Texas Instruments' AUP logic family, housed in a 6-pin SON (DSF) package. It operates within a supply voltage range of 0.8 V to 3.6 V and supports an operating temperature from -40°C to +85°C. The device features low static power consumption with a maximum ICC of 0.9 µA and typical dynamic power dissipation capacitance of 4 pF at 3.3 V. Propagation delay reaches a maximum of 4.8 ns at 3.3 V with a 5 pF load. Input hysteresis is typically 250 mV at 3.3 V, and the I/Os are tolerant up to 3.6 V.

Feature Summary

• Ultra-low quiescent and dynamic power consumption suitable for battery-powered applications
• Input hysteresis provides improved noise immunity during slow input transitions
• Ioff circuitry prevents back-driving current when powered down, supporting live insertion
• Low noise overshoot and undershoot due to optimized edge rates

Applications

• Active Noise Cancellation (ANC)
• Embedded PC systems
• Server motherboard and PSU logic
• Wireless data access cards and peripherals
• Medical devices such as blood pressure monitors

Procurement Notes

Verify the specific DSF package variant against the orderable addendum in the datasheet to ensure correct pinout and mechanical dimensions. Confirm that the application environment remains within the specified -40°C to +85°C operating temperature range. Ensure unused inputs are tied to VCC or GND to prevent floating states and excessive current draw. Check ESD handling requirements during assembly.

Selection Notes

Select this component for designs requiring minimal board space and ultra-low power in portable electronics. The 3.6-V I/O tolerance allows compatibility with mixed-mode signal operations involving 3.3-V systems. Consider the propagation delay specifications relative to the system clock speed and load capacitance requirements. Verify that the output drive capabilities meet the downstream input requirements without exceeding the 20 mA continuous output current limit.

Part Context

This device belongs to the SN74AUP1Gxx series, representing Texas Instruments' ultra-low power single-gate logic solutions.

FAQ

How does the Ioff feature function?

The Ioff circuitry disables the outputs when VCC is 0 V, preventing damaging current backflow through the device. This supports partial-power-down modes and live insertion.

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, ensuring stable operation in noisy environments.
