SN74AUC2G00DCURG4

Overview

The SN74AUC2G00DCURG4 is a dual 2-input positive-NAND gate from the Texas Instruments AUC series, designed for low-power applications. It operates within a supply voltage range of 0.8 V to 2.7 V and supports mixed-mode signal environments with inputs tolerating up to 3.6 V. The device features an Ioff circuit that enables partial-power-down mode by disabling outputs to prevent damaging backflow current. It provides ±8-mA output drive at 1.8 V and includes ESD protection exceeding JESD 22 standards. The component is housed in an 8-pin VSSOP (DCU) package.

Feature Summary

• Supports partial-power-down operation via integrated Ioff circuitry to prevent output backflow
• Optimized for 1.8-V logic levels while maintaining compatibility with 3.6-V I/O interfaces
• Provides high noise immunity through latch-up performance exceeding 100 mA per JESD 78 Class II

Applications

• Mixed-mode signal processing circuits requiring level translation between different voltage domains
• Portable battery-powered devices necessitating ultra-low standby power consumption
• High-speed digital logic systems operating under strict voltage constraints

Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to lead-free and RoHS-compliant manufacturing specifications as defined in the official datasheet. Confirm the DCU package variant matches the required PCB footprint dimensions. Ensure the procurement channel sources production data directly from Texas Instruments or authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when designing circuits that require NAND functionality within a minimal physical footprint. It is suitable for applications demanding operation below 1 V where standard CMOS logic may fail. Consider the VSSOP package constraints regarding thermal dissipation and board space availability compared to larger packages like SSOP or DSBGA.

Part Context

This part belongs to the SN74AUC family of advanced ultra-low-power CMOS logic devices. The AUC series is engineered specifically for portable electronics and battery-operated systems. It utilizes Texas Instruments NanoFree technology concepts to achieve high performance with reduced parasitic capacitance and lower power consumption compared to legacy logic families.

Replacement Considerations

The SN74AUC2G00DCTR serves as a functional equivalent utilizing the SSOP (DCT) package instead of the VSSOP configuration.
