SN74AUC2G86DCTR

Overview

The SN74AUC2G86DCTR is a dual XOR gate integrated circuit from Texas Instruments, belonging to the AUC logic series. It operates within a supply voltage range of 0.8 V to 2.7 V and features two independent gates with single-ended inputs and outputs. The device provides a propagation delay of 2.4 ns at 5 V and 3.6 ns at 3.3 V under specific load conditions. It supports output currents of -9 mA (high) and 9 mA (low), ensuring robust signal driving capabilities in low-voltage applications.

Feature Summary

• Dual-channel exclusive-OR logic functionality for compact digital processing
• High-speed operation with minimal propagation delay in sub-3V environments
• Single-ended input and output configuration for straightforward integration

Applications

• Low-voltage digital logic circuits requiring XOR operations
• Portable electronic devices operating on single-supply power
• Data path switching and parity generation in embedded systems

Procurement Notes

Verify the exact ordering suffix against the manufacturer's current datasheet to confirm package type and tape/reel specifications. Ensure compatibility with the target PCB footprint and soldering profile. Confirm RoHS compliance status as required by regional regulations before finalizing procurement orders.

Selection Notes

Select this component when designing for ultra-low voltage operation below 3.3 V where standard LVC or HCT families are unsuitable. Consider the 2.4 ns propagation delay for high-frequency timing requirements. Evaluate the VSSOP-8 package dimensions against available board space constraints during the schematic capture phase.

Part Context

This part belongs to the SN74AUC2Gxx family of Texas Instruments, designed for advanced ultra-low voltage CMOS technology. It complements other dual-gate variants like the SN74AUC2G79DCUR flip-flop and SN74AUC2G66DCUR analog switch, offering a consistent pinout and electrical characteristic set across the series for modular design scalability.

Replacement Considerations

Check for direct pin-compatible alternatives such as the SN74LVC2G86DCTR if higher voltage tolerance up to 5.5 V is acceptable. Verify that any substitute maintains the same 0.8 V to 2.7 V operating range and propagation delay characteristics to ensure circuit performance integrity.
