SN74AUC2G08DCURE4

Overview

The SN74AUC2G08DCURE4 is a dual 2-input positive-AND gate from the Texas Instruments AUC logic series. 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 low power consumption with a typical quiescent current of 10 μA at 1.8 V and supports ±8-mA output drive at 1.8 V. Propagation delay is typically 1.5 ns at 1.8 V with a 30-pF load. It includes Ioff support for partial-power-down mode and offers ESD protection exceeding 2000 V (HBM) and 1000 V (CDM).

Feature Summary

• Dual 2-input positive-AND logic function in a compact NanoFree package.
• Operational across a wide supply voltage range of 0.8 V to 2.7 V.
• Supports partial-power-down mode via integrated Ioff circuitry to prevent backflow.
• High ESD protection performance exceeding JESD standards.

Applications

• Mixed-mode signal operation supporting 3.6-V I/O levels.
• Partial-power-down applications requiring output disabling during power-off states.
• Low-voltage digital logic circuits optimized for 1.8-V systems.

Procurement Notes

Verify that the ordering suffix 'E4' corresponds to the specific lead finish or environmental compliance designation required for your assembly process. Confirm the DCU package type matches your PCB footprint specifications. Ensure compatibility with the -40°C to +85°C operating temperature range defined in the datasheet. Cross-reference the RoHS status and MSL rating with your manufacturing facility's requirements before finalizing procurement.

Selection Notes

Select this component when a dual AND gate is required for sub-1-V to 2.7-V logic domains. The AUC series is suitable for designs prioritizing low power consumption and high speed relative to standard CMOS families. Consider the VSSOP-8 package dimensions if board space is constrained. Verify input voltage thresholds against your system's logic levels to ensure reliable switching characteristics under varying supply conditions.

Part Context

This part belongs to the SN74AUC2Gxx family of Little Logic devices, designed for ultra-low voltage and low power applications. The AUC series bridges the gap between traditional 5-V and 3.3-V logic families and modern sub-1-V portable electronics. The DCU package variant provides a small outline solution suitable for surface-mount assembly techniques common in consumer and industrial electronics.
