74ALVC86M

Overview

The Fairchild Semiconductor 74ALVC86M is a high-speed CMOS quad XOR gate operating from a 2.7V to 3.6V supply. It features low dynamic power consumption and supports 5V tolerant I/Os for mixed-signal applications. The device utilizes advanced semiconductor technology to achieve propagation delays of typically 4.5ns at 3.3V. It is housed in a standard SOIC-14 package, ensuring compatibility with existing PCB footprints while providing robust noise immunity and stable logic levels across the specified voltage range.

Feature Summary

• High-speed operation with low propagation delay
• 5V tolerant inputs compatible with 3.3V systems
• Low static and dynamic power consumption
• Robust latch-up performance under ESD stress

Applications

• Data acquisition systems
• Communication equipment signal processing
• Consumer electronics logic control
• Industrial control system interfaces

Procurement Notes

Verify the specific suffix 'M' indicates the tape and reel packaging variant rather than just the SOIC package. Confirm the manufacturer date code and lot traceability requirements for your production line. Ensure the component meets RoHS compliance standards if required by your regional regulations. Check for any specific handling precautions related to electrostatic discharge during assembly processes.

Selection Notes

Select this component when a quad XOR function is required within a 3.3V logic environment. It is suitable for designs needing 5V tolerance on inputs while maintaining low power dissipation. Consider this part for space-constrained applications due to its compact SOIC-14 footprint. Ensure the operating temperature range aligns with your system's environmental conditions.

Part Context

This component belongs to the ALVC (Advanced Low Voltage CMOS) family, designed for high-speed digital applications. It serves as a direct replacement for older LS or ALS series gates in modern low-voltage designs. The XOR functionality is essential for parity checking and arithmetic operations in digital circuits.

Replacement Considerations

Direct pin-compatible alternatives include the SN74ALVC86 from Texas Instruments or the MC74ALVC86 from ON Semiconductor. Verify that substitute parts maintain the same 5V tolerant input specifications and package dimensions to ensure seamless integration without PCB redesign.
