SN74AC86D

Overview

The SN74AC86D is a quad two-input exclusive-OR gate manufactured by Texas Instruments. It contains four independent XOR gates, each performing the Boolean function Y=A ⊕ B. The device operates within a wide supply voltage range of 2V to 6V and features buffered inputs. It utilizes advanced AC CMOS technology to deliver high-speed performance with low power consumption. The component is housed in a 14-pin SOIC package.

Feature Summary

• Contains four independent two-input exclusive-OR logic gates
• Operates across a wide supply voltage range from 2V to 6V
• Features buffered inputs for improved signal integrity

Applications

• Digital logic comparison circuits
• Parity checkers and generators
• Arithmetic logic units (ALUs)

Procurement Notes

Verify the specific suffix 'D' corresponds to the 14-pin Small Outline Integrated Circuit (SOIC) package configuration. Confirm that the part meets RoHS compliance standards as indicated by manufacturer documentation. Ensure compatibility with the target operating voltage range of 2V to 6V before integration into the design.

Selection Notes

Select this component when multiple independent XOR functions are required in a single package. The AC series offers higher speed compared to standard HC or LS families. Verify that the 14-pin SOIC footprint matches the PCB layout requirements. Consider the 2V to 6V operating range for flexibility in various digital system designs.

Part Context

This component belongs to the Texas Instruments 74AC logic family, which provides high-speed CMOS performance. The 74AC86 specifically implements the XOR logic function. It is designed for general-purpose digital applications requiring reliable logical operations. The device is part of a broader ecosystem of compatible logic ICs from the manufacturer.

Replacement Considerations

Compatible substitutes include other quad XOR gates such as the SN74HC86 or SN74AHC86. Verify pinout compatibility and electrical specifications before substitution. Ensure the alternative part supports the required supply voltage and package type.
