SN74AC86N

Overview

The SN74AC86N is a quadruple 2-input exclusive-OR gate manufactured by Texas Instruments. It belongs to the AC logic series and features buffered inputs with a wide operating voltage range from 2 V to 6 V. The device provides four independent XOR gates, each executing the Boolean function Y=A ⊕ B. Key electrical specifications include a propagation delay of 9 ns, low-level output current of 24 mA, and high-level output current of -24 mA. It operates within a temperature range of -40 °C to +85 °C and utilizes a TSSOP-14 package.

Feature Summary

• Contains four independent 2-input exclusive-OR gates for complex logic implementation
• Buffered inputs ensure stable signal integrity across the specified voltage range
• High drive capability supports direct interfacing with standard logic loads

Applications

• Digital data processing circuits requiring parity generation or checking
• Arithmetic logic units performing binary addition operations
• Comparator circuits for detecting inequality between digital signals

Procurement Notes

Verify the specific suffix 'N' against official documentation, as it typically denotes a PDIP-14 package in standard naming conventions, while datasheets may list TSSOP variants. Confirm RoHS compliance status directly with the manufacturer's latest release notes. Ensure the ordering part number matches the exact package style required for your PCB footprint to avoid assembly errors.

Selection Notes

Select this component when a wide supply voltage range of 2 V to 6 V is required compared to standard 5 V only logic families. The AC series offers faster switching speeds than HC/UH counterparts while maintaining CMOS power efficiency. Consider the TSSOP-14 package if surface-mount technology is preferred for compact board designs.

Part Context

This device is part of the broader SN74xx logic family, specifically the AC (Advanced CMOS) sub-family. It serves as a fundamental building block for sequential and combinational logic design. The SN74AC86N complements other AC series gates like inverters and NANDs to create complete digital systems within Texas Instruments' standardized logic portfolio.
