SN74AHC86D

Overview

The SN74AHC86D is a quad 2-input exclusive-OR gate from the Texas Instruments AHC logic family. It operates within a supply voltage range of 2 V to 5.5 V and features low dynamic power consumption. The device provides symmetric output drive capabilities with a low-level output current of 8 mA and a high-level output current of -8 mA. Propagation delay is specified at 10 ns. It functions reliably across an extended temperature range from -40°C to +125°C and utilizes a 14-pin SOIC package.

Feature Summary

• Provides four independent 2-input exclusive-OR logic functions in a single package
• Operates over a wide supply voltage range from 2 V to 5.5 V
• Features low dynamic power consumption typical for CMOS technology
• Supports surface-mount installation via standard SOIC packaging

Applications

• Digital signal processing circuits requiring XOR functionality
• Parity checkers and error detection systems
• Arithmetic logic units (ALUs) for addition operations
• Data path switching and multiplexing applications

Procurement Notes

Verify the specific suffix against official documentation, as variations may indicate different tape-and-reel quantities or environmental compliance levels. Confirm the package type matches design requirements, as SOIC dimensions are critical for PCB footprint compatibility. Ensure the operating temperature range aligns with system thermal constraints. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Selection Notes

Select this component when a quad XOR configuration is required within the AHC performance envelope. The 2 V to 5.5 V supply range offers flexibility for mixed-voltage systems. Consider the 10 ns propagation delay for timing-critical paths. Evaluate the 8 mA drive strength against load capacitance requirements. Compare against HC series variants if lower cost is prioritized over speed, or LVC series if lower voltage operation below 2 V is necessary.

Part Context

This part belongs to the SN74AHC86 series, which integrates four independent 2-input exclusive-OR gates. The AHC series represents an advanced high-speed CMOS technology designed for high-speed digital applications. It serves as a functional equivalent to older TTL-based XOR gates while offering improved power efficiency and wider voltage tolerance. The SOIC package provides a compact solution for space-constrained designs.

Replacement Considerations

SN74AHC86DRG4: Same logic function and pinout; verify package and reel specifications. SN74AHC86DGVR: Same logic function; confirm tape-and-reel orientation and package variant. SN74AHC86N: Same logic function; note difference in package style (PDIP vs SOIC).
