CD74HCT86MT XOR Logic IC Equivalent & Substitute Parts

Part Overview

The CD74HCT86MT is a 4-channel, 2-input XOR (Exclusive OR) logic gate integrated circuit manufactured by Texas Instruments in a 14-SOIC surface mount package. This part is discontinued at DiGi Electronics, making equivalent substitute parts necessary for ongoing design support and procurement. The 74HCT86 logic family provides standard XOR functionality across multiple manufacturers, with several active alternatives available that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the CD74HCT86MT is determined by strict equivalence across the following parameters: logic type (XOR, 4-channel, 2-input configuration), supply voltage range (4.5V ~ 5.5V minimum), output current capability (4mA), input logic thresholds (0.8V low, 2V high), propagation delay performance (32ns maximum), operating temperature range, package type (14-SOIC), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are grouped into two categories:

Parametric Equivalents: Parts that match all critical electrical parameters and package specifications of the original CD74HCT86MT, differing only in packaging format (Cut Tape vs. Tape & Reel) or manufacturer.

Manufacturer Recommended Alternatives: Parts from alternative manufacturers (Nexperia, Diodes Incorporated, onsemi) that maintain functional and electrical equivalence with documented compatibility to the 74HCT86 base product number.

Engineering Selection Recommendations

Primary Substitute (Highest Compatibility): CD74HCT86M96 from Texas Instruments is the direct parametric equivalent to the discontinued CD74HCT86MT. It maintains identical electrical specifications and operates across the same temperature range. The only difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). This part is currently active with 15,664 units in stock.

Secondary Substitutes (Nexperia): The 74HCT86D,653 and 74HCT86D-Q100,118 from Nexperia USA Inc. are functionally equivalent with identical electrical parameters. The 74HCT86D-Q100,118 carries AEC-Q100 automotive qualification, suitable for applications requiring automotive-grade components. Both parts operate at -40°C to 125°C, which covers the original -55°C to 125°C range except at the lower extreme.

Alternative Substitute (onsemi): The MC74HCT86ADR2G from onsemi provides enhanced performance characteristics, including wider supply voltage range (2V ~ 6V), lower quiescent current (1 µA), and faster propagation delay (20ns @ 5V). This part maintains the original operating temperature range (-55°C ~ 125°C) and is suitable for applications requiring improved power efficiency or faster logic switching.

Quiescent Current Consideration: The 74HCT86S14-13 from Diodes Incorporated specifies 20 µA maximum quiescent current, compared to 2 µA for the original part. This higher current consumption may impact power budget calculations in battery-powered or low-power applications.

All substitute parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.

Frequently Asked Questions (FAQ)

Q: Can I directly replace CD74HCT86MT with CD74HCT86M96?

A: Yes. CD74HCT86M96 is a parametric equivalent with identical electrical specifications and operating temperature range. The difference is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel). Both are 14-SOIC surface mount packages with identical pinout and functionality.

Q: What is the difference between the Nexperia parts 74HCT86D,653 and 74HCT86D-Q100,118?

A: Both parts are electrically identical. The 74HCT86D-Q100,118 includes AEC-Q100 automotive qualification and is supplied in Tape & Reel format. The 74HCT86D,653 is supplied in Cut Tape & Digi-Reel® format. Select based on packaging requirements and whether automotive qualification is needed.

Q: Why does MC74HCT86ADR2G have different electrical specifications?

A: The MC74HCT86ADR2G from onsemi is a performance-enhanced variant of the 74HCT86 logic family. It maintains functional equivalence (4-channel, 2-input XOR) but offers improved specifications: wider supply voltage range (2V ~ 6V), lower quiescent current (1 µA), and faster propagation delay (20ns @ 5V). It is suitable as a direct replacement when these enhanced characteristics are beneficial.

Q: Is the 74HCT86S14-13 from Diodes Incorporated a suitable replacement?

A: The 74HCT86S14-13 is functionally equivalent and maintains the same logic configuration, package, and propagation delay. However, it specifies 20 µA maximum quiescent current compared to 2 µA for the original CD74HCT86MT. Use this part only if quiescent current specifications are not critical to your application.

Q: Do all substitute parts use the same 14-SOIC package?

A: Yes. All substitute parts use the 14-SOIC (0.154", 3.90mm Width) surface mount package with identical pinout. They are mechanically and electrically interchangeable at the board level.

Q: What is the operating temperature difference between the original part and Nexperia substitutes?

A: The CD74HCT86MT operates from -55°C to 125°C. The Nexperia parts (74HCT86D,653 and 74HCT86D-Q100,118) operate from -40°C to 125°C. If your application requires operation below -40°C, use CD74HCT86M96 or MC74HCT86ADR2G, which maintain the -55°C lower limit.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
