SN74AUP2G02DQER

Overview

The SN74AUP2G02DQER is a low-power dual 2-input positive-NOR gate from Texas Instruments, part of the AUP logic series. It operates within a supply voltage range of 800 mV to 3.6 V and supports I/O levels up to 3.6 V for mixed-mode system applications. The device features a propagation delay of 18 ns at 0.8 V with 10 pF load and consumes 900 nA of operating current. It is housed in an 8-X2SON package (1.4x1 mm) suitable for surface-mount installation.

Feature Summary

• Optimized for low-power operation with minimal static and dynamic current consumption
• Supports mixed-mode environments through 3.6-V I/O tolerance despite lower supply voltages
• Compact NanoStar package design enables high-density circuit board layouts

Applications

• Portable battery-powered consumer electronics requiring extended standby times
• Mixed-voltage digital logic interfacing between different power domains
• Space-constrained embedded systems utilizing high-density surface-mount packaging

Procurement Notes

Verify the specific suffix DQER corresponds to the X2SON-8 package and tape-and-reel configuration required for your assembly process. Confirm that the 3.6-V I/O tolerance aligns with your target system voltage levels. Ensure ESD handling protocols are followed due to the small form factor and sensitive CMOS input structures inherent to the AUP series.

Selection Notes

Select this component when minimizing power consumption is critical alongside strict space limitations. The AUP series offers superior speed-to-power efficiency compared to older CMOS families. Consider the 800 mV minimum supply requirement to ensure reliable operation in ultra-low-voltage scenarios where standard 5-V or 3.3-V tolerant devices may not function correctly.

Part Context

This device belongs to the SN74AUP2Gxx family of single-function gates designed for ultra-low-power applications. The AUP series utilizes advanced CMOS technology to achieve performance levels comparable to faster logic families while maintaining significantly lower power dissipation. The dual 2-input NOR configuration provides two independent logic functions within a minimal footprint.

FAQ

What is the maximum I/O voltage tolerance for the SN74AUP2G02DQER?

The inputs are tolerant to 3.6 V, allowing safe interfacing with 3.3-V systems even when the device operates at lower supply voltages.

Does the SN74AUP2G02DQER support bidirectional data transmission?

No, this is a unidirectional logic gate. Bidirectional transmission requires tri-state bus transceivers such as those in the SN74AUP2G240 series.
