SN74AUC2G08DCURG4

Overview

The SN74AUC2G08DCURG4 is a dual 2-input positive-AND gate from the Texas Instruments AUC logic family. It operates within a supply voltage range of 0.8 V to 2.7 V and supports mixed-mode signal operation with 3.6-V I/O tolerance. The device features low power consumption, drawing 10 µA at 1.8 V, and provides ±8-mA output drive capability. Propagation delay is optimized for high-speed applications, reaching a maximum of 1.5 ns at 1.8 V. It includes Ioff circuitry to support partial-power-down modes and offers robust ESD protection exceeding JESD 22 standards.

Feature Summary

• Supports mixed-mode signal operations through 3.6-V I/O tolerance while operating at lower supply voltages.
• Includes dedicated Ioff circuitry that disables outputs to prevent damaging current backflow during partial-power-down states.
• Provides enhanced electrostatic discharge protection capabilities that exceed standard JESD 22 testing requirements.

Applications

• Mixed-mode signal processing environments requiring voltage level translation between different logic families.
• Portable battery-powered devices where minimizing quiescent power consumption is critical.
• Systems utilizing partial-power-down modes to manage standby currents effectively.

Procurement Notes

Verify the specific package marking code U08R on the component surface to confirm the DCU (VSSOP) variant. Ensure the ordering suffix G4 corresponds to lead-free and RoHS-compliant specifications as defined in the manufacturer's packaging addendum. Cross-reference the full part number against official distributor catalogs to validate active production status and availability constraints.

Selection Notes

Select this component when designing circuits that require dual AND functionality within a minimal footprint. The VSSOP package is suitable for space-constrained printed circuit board layouts. Consider the 3.6-V input tolerance if interfacing with higher voltage logic sources without additional level shifting components. Evaluate the propagation delay specifications against system timing requirements to ensure signal integrity.

Part Context

This device belongs to the Texas Instruments AUC Little Logic series, which focuses on sub-1-V operability and ultra-low power consumption. The AUC family utilizes advanced semiconductor processes to achieve high switching speeds while maintaining low static power dissipation. This specific model integrates two independent logic gates into a single compact integrated circuit structure.
