SN74AUC08RGYR

Overview

The SN74AUC08RGYR 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 is optimized for 1.65-V to 1.95-V applications. The device features a maximum propagation delay of 1.9 ns at 1.8 V, with output drive capabilities of ±8 mA at 1.8 V. It includes Ioff circuitry to support partial-power-down mode, preventing backflow current. The component is housed in a 14-pin VQFN package and supports mixed-mode signal operation with 3.6-V I/O tolerance.

Feature Summary

• Supports partial-power-down mode via integrated Ioff circuitry to prevent damaging backflow currents
• Optimized for 1.8-V operation while maintaining 3.6-V I/O tolerance for mixed-mode signal compatibility
• Provides high-speed performance with a maximum propagation delay of 1.9 ns at 1.8 V
• Features robust ESD protection exceeding JESD 22 standards for human-body, machine, and charged-device models

Applications

• Mixed-mode signal processing between different voltage domains
• Partial-power-down system configurations requiring output disabling
• High-speed digital logic circuits operating at low voltages

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the moisture sensitivity level and reflow temperature profiles align with your assembly process requirements. Ensure the RoHS compliance status meets your regulatory standards. Cross-reference the active production status to confirm long-term availability before finalizing procurement plans.

Selection Notes

Select this component when designing systems requiring low-voltage AND logic with mixed-mode I/O capabilities. The AUC series offers superior speed and power efficiency compared to legacy families. Consider the VQFN package size for space-constrained layouts. Verify that the 3.6-V input tolerance satisfies the interface requirements of higher-voltage control signals.

Part Context

This part belongs to the SN74AUCxx family of advanced ultra-low voltage CMOS logic devices. The AUC series is designed specifically for sub-1-V to 2.7-V operations, offering significant power savings. The quadruple 2-input AND gate function provides four independent logic channels within a single compact package, suitable for complex digital control applications.

Replacement Considerations

Direct replacements include SN74AUC08RGYT or SN74AUC08RGYRG4. Verify pinout compatibility and electrical specifications before substitution.
