SN74AUC08RGYRG4

Overview

The SN74AUC08RGYRG4 is a quadruple 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 and features an RGY package (VQFN-14). The device supports mixed-mode signal operation with 3.6-V I/O tolerance while operating at 1.8 V. Key electrical parameters include a maximum propagation delay of 1.9 ns at 1.8 V, ±8-mA output drive capability, and a maximum quiescent current of 10 μA.

Feature Summary

• Supports partial-power-down mode via integrated Ioff circuitry that disables outputs to prevent damaging backflow currents.
• Optimized for 1.8-V operation with 3.6-V I/O tolerance to facilitate mixed-mode signal environments.
• Provides high-speed performance with a maximum propagation delay of 1.9 ns at 1.8 V.

Applications

• Mixed-mode signal processing applications requiring level translation between low-voltage cores and 3.6-V interfaces.
• Portable and battery-powered systems utilizing sub-1-V operability and low power consumption.
• Digital logic circuits implementing Boolean AND functions in space-constrained designs using the VQFN package.

Procurement Notes

Verify the specific ordering suffix 'G4' corresponds to RoHS-compliant manufacturing standards as indicated in TI documentation. Confirm the moisture sensitivity level (MSL 2) and peak reflow temperature requirements align with your assembly process capabilities. Ensure the VQFN-14 package thermal impedance characteristics are accounted for in your PCB layout design to maintain reliable operation within the specified -40°C to 85°C temperature range.

Selection Notes

Select this component when designing systems requiring low-voltage operation down to 0.8 V combined with 3.6-V tolerant inputs. The SN74AUC08RGYRG4 is suitable for applications prioritizing minimal power consumption and high-speed switching speeds under 1.8-V supply conditions. Consider the VQFN-14 package dimensions if board space is limited compared to traditional leaded packages.

Part Context

This part belongs to the SN74AUC08 family of quadruple 2-input positive-AND gates manufactured by Texas Instruments. It utilizes the AUC logic series technology, which is engineered for ultra-low voltage applications. The device is distinct from other logic families by its specific optimization for 1.8-V operation and its inclusion of Ioff features for power-down protection.

Replacement Considerations

The SN74AUC08RGYR is listed as a manufacturer-recommended alternative to the SN74AUC08RGYRG4. Both parts share identical functional specifications and packaging but may differ in environmental compliance or manufacturing lot details.
