CD74AC86M XOR Logic IC Equivalent & Substitute Parts

Part Overview

The CD74AC86M is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by Texas Instruments in 14-SOIC surface mount packaging. This part is classified as Last Time Buy, indicating limited availability from the original manufacturer. The CD74AC86M operates across a supply voltage range of 1.5V to 5.5V with a maximum propagation delay of 10.8ns at 5V with 50pF load. Finding equivalent and substitute parts is necessary due to the Last Time Buy status and to ensure design flexibility across multiple sourcing channels and manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CD74AC86M is determined by the following critical parameters:

• Logic Function: All substitutes must implement 4-channel, 2-input XOR logic
• Package Type: All substitutes must use 14-SOIC surface mount packaging with identical pinout
• Supply Voltage Range: Substitutes must support the required operating voltage window
• Output Drive Capability: Output current specifications (24mA high/low) must be met
• Propagation Delay: Maximum delay specifications must not exceed application requirements
• Operating Temperature Range: Substitutes must cover the required temperature window
• Compliance: RoHS3 compliance is required for modern applications

Substitutes are grouped by manufacturer and packaging variation while maintaining functional and electrical equivalence within the 74AC86 logic family.

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: CD74AC86M96

The CD74AC86M96 is the direct functional equivalent manufactured by Texas Instruments with Active product status. It maintains identical electrical specifications to the CD74AC86M (1.5V ~ 5.5V supply, 10.8ns propagation delay, -55°C ~ 125°C operating range) and differs only in packaging format (Cut Tape & Digi-Reel versus Tube). This part is suitable for designs requiring the extended supply voltage range and temperature specifications of the original CD74AC86M.

Secondary Recommendations: MC74AC86DG and MC74AC86DR2G

The onsemi MC74AC86DG and MC74AC86DR2G are Active products with RoHS3 compliance and identical electrical performance. These parts operate within 2V ~ 6V supply range and -40°C ~ 85°C temperature window. The MC74AC86DR2G in Tape & Reel packaging is optimized for high-volume production, while MC74AC86DG in Tube packaging suits lower-volume applications.

Alternative Options: 74AC86SC and 74AC86SCX

The Fairchild Semiconductor 74AC86SC and 74AC86SCX are Active products with improved propagation delay (8.5ns) and lower quiescent current (2 µA). These parts operate within 2V ~ 6V supply and -40°C ~ 85°C temperature range. Selection of these alternatives is appropriate when the narrower supply voltage and temperature specifications align with application requirements.

Discontinued Part: SN74AC86D

The SN74AC86D is marked as Discontinued at DiGi Electronics and should not be selected for new designs despite Active status at other sources.

Frequently Asked Questions (FAQ)

Q: Can I substitute CD74AC86M with CD74AC86M96?

A: Yes. Both parts are manufactured by Texas Instruments with identical electrical specifications (1.5V ~ 5.5V supply, 10.8ns propagation delay, -55°C ~ 125°C operating range). The difference is packaging format: CD74AC86M uses Tube while CD74AC86M96 uses Cut Tape & Digi-Reel. Pinout and functional performance are identical.

Q: What is the difference between the Texas Instruments and onsemi versions?

A: Both manufacturers produce 74AC86 logic ICs with the same functional behavior and 14-SOIC pinout. Texas Instruments CD74AC86M96 supports 1.5V ~ 5.5V supply and -55°C ~ 125°C operation. onsemi MC74AC86DG and MC74AC86DR2G support 2V ~ 6V supply and -40°C ~ 85°C operation. Selection depends on your specific supply voltage and temperature requirements.

Q: Can I use Fairchild 74AC86SC in place of CD74AC86M?

A: Functional substitution is possible if your application operates within 2V ~ 6V supply voltage and -40°C ~ 85°C temperature range. The 74AC86SC has faster propagation delay (8.5ns versus 10.8ns) and lower quiescent current (2 µA versus 4 µA). If your design requires the extended -55°C lower temperature limit or 1.5V minimum supply voltage of the CD74AC86M, the 74AC86SC is not suitable.

Q: What packaging options are available for 74AC86 logic ICs?

A: Available packaging formats include Tube (MC74AC86DG, SN74AC86D, CD74AC86M), Cut Tape & Digi-Reel (CD74AC86M96), Tape & Reel (MC74AC86DR2G), and Bulk (74AC86SCX). Selection depends on order quantity and assembly process requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Texas Instruments CD74AC86M96, onsemi MC74AC86DG, and onsemi MC74AC86DR2G are explicitly RoHS3 compliant. Fairchild Semiconductor 74AC86SC and 74AC86SCX do not list RoHS status in provided specifications. Texas Instruments SN74AC86D is RoHS3 compliant but discontinued at DiGi Electronics.

Q: Which substitute has the fastest propagation delay?

A: Fairchild 74AC86SC, 74AC86SCX, onsemi MC74AC86DG, MC74AC86DR2G, and Texas Instruments SN74AC86D all specify 8.5ns propagation delay at 5V with 50pF load, compared to 10.8ns for the CD74AC86M and CD74AC86M96.
