SN74AUC2G32DCUR

Overview

The SN74AUC2G32DCUR is a dual 2-input positive-OR gate from Texas Instruments, operating within an ultra-low voltage range of 0.8 V to 2.7 V. It features a propagation delay of 2.4 ns and provides ±9 mA output drive current at 1.8 V. The device is housed in an 8-pin VSSOP (DCU) NanoFree package, suitable for surface-mount applications. It supports mixed-mode signal operation with 3.6-V I/O tolerance while maintaining low power consumption of 10 µA at 1.8 V.

Feature Summary

• Ultra-low voltage operation optimized for 1.8-V systems
• High-speed performance with 2.4 ns propagation delay
• Mixed-mode signal compatibility via 3.6-V I/O tolerance

Applications

• Portable battery-powered electronic devices
• Mixed-voltage digital logic interfacing
• Space-constrained embedded system designs

Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration. Confirm the DCU package designation matches the required VSSOP-8 footprint for PCB layout. Ensure supply chain sources provide original manufacturer documentation to validate RoHS compliance and revision status before integration into production schedules.

Selection Notes

Select this component when designing circuits requiring sub-1-V operation or strict power constraints. The 2.4 ns speed suits high-frequency logic paths where minimal latency is critical. Consider the 3.6-V I/O tolerance if interfacing with slightly higher voltage domains without level shifting components.

Part Context

This part belongs to the SN74AUC2G series of ultra-low-voltage logic gates. It shares the NanoFree package family with other AUC devices but differs in function as an OR gate rather than a flip-flop or inverter. The series targets modern portable electronics demanding miniaturization and energy efficiency.

Replacement Considerations

Check for SN74AUC2G32DCTAR as an alternative reel option. Verify pinout compatibility with existing layouts when substituting.
