SN74AUC2G00DCURE4

Overview

The SN74AUC2G00DCURE4 is a dual 2-input positive-NAND gate from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V, optimized for 1.65-V to 1.95-V applications. The device features an Ioff circuit supporting partial-power-down mode and provides ±8-mA output drive at 1.8 V. Propagation delay (tpd) is typically 0.9 ns at 1.8 V with a 15-pF load. Input clamp current (IIK) and output clamp current (IOK) are rated at -50 mA. Operating temperature spans -40 °C to +85 °C.

Feature Summary

• Dual 2-input NAND logic function in a compact NanoFree package
• Ioff circuitry enables partial-power-down operation without damaging backflow
• ESD protection exceeds JESD 22 standards for robust signal integrity

Applications

• Mixed-mode signal processing circuits
• Portable and battery-powered electronic devices
• Consumer electronics requiring low power consumption

Procurement Notes

Verify the E4 suffix indicates lead-free construction conforming to RoHS standards. Confirm the DCU package designation matches the required VSSOP footprint. Ensure the ordering part number aligns with the specific reel quantity and tape orientation specified in the packaging data sheet.

Selection Notes

Select this component for designs requiring sub-1-V operability and high-speed switching. The AUC series offers lower power dissipation compared to legacy families. Verify input transition rates do not exceed 20 ns/V to maintain timing specifications. Check thermal impedance requirements against the selected package type.

Part Context

This device belongs to the SN74AUC2Gxx series of ultra-low-power CMOS logic gates. It utilizes Texas Instruments' NanoFree technology, which integrates the die directly into the package structure. The AUC family is designed specifically for 1.8-V systems while maintaining compatibility with 3.6-V I/O interfaces.
