Engineering Selection Recommendations

Primary Active Substitutes (Recommended for New Designs):

MC74HC86ADG and MC74HC86ADR2G from onsemi and Fairchild Semiconductor respectively offer superior performance with reduced quiescent current (1 µA vs. 2 µA) and faster propagation delay (17ns vs. 20ns). Both parts maintain full compatibility with the MM74HC86MX electrical specifications and extend the operating temperature range to -55°C ~ 125°C. These parts are currently in active production status.

74HC86S14-13 from Diodes Incorporated provides the fastest propagation delay (15ns) and extended upper operating temperature to 125°C. This part is actively produced with high inventory availability (47,800 units). The higher quiescent current specification (20 µA) remains within acceptable limits for most applications.

Direct Electrical Equivalents (Pin-Compatible Replacements):

CD74HC86M96 from Texas Instruments matches the MM74HC86MX electrical specifications exactly (2 µA quiescent current, 20ns propagation delay) while offering extended temperature range (-55°C ~ 125°C). This part is actively produced with 1,495 units in stock.

74HC86D,653 from Nexperia USA Inc. provides identical electrical performance to the MM74HC86MX with extended upper operating temperature to 125°C. This part is actively produced with 2,700 units available.

Automotive-Grade Alternative:

74HC86D-Q100,118 from Nexperia USA Inc. is qualified to AEC-Q100 automotive standards and maintains identical electrical specifications to the MM74HC86MX. This part is suitable for applications requiring automotive-grade components and is actively produced with 3,375 units in stock.

Parts to Avoid for New Designs:

NLV74HC86ADR2G is marked as obsolete. CD74HC86M and CD74HC86MT are either obsolete or discontinued at DiGi Electronics. SN74HC86D is discontinued at DiGi Electronics. These parts should only be considered for legacy system maintenance where no alternatives are available.

Frequently Asked Questions (FAQ)

Q: Can I use MC74HC86ADG as a direct replacement for MM74HC86MX?

A: Yes. MC74HC86ADG is electrically compatible with MM74HC86MX. Both parts share identical logic type (4-channel XOR), input/output specifications, and 14-SOIC package. MC74HC86ADG offers improved performance with lower quiescent current (1 µA vs. 2 µA) and faster propagation delay (17ns vs. 20ns). The primary difference is packaging format (Tube vs. Tape & Reel) and extended operating temperature range (-55°C ~ 125°C vs. -40°C ~ 85°C).

Q: What is the difference between 74HC86D,653 and 74HC86D-Q100,118?

A: Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications. The primary difference is that 74HC86D-Q100,118 carries AEC-Q100 automotive qualification, making it suitable for automotive applications. Select 74HC86D-Q100,118 when automotive-grade certification is required; otherwise, 74HC86D,653 is functionally equivalent.

Q: Why does 74HC86S14-13 show higher quiescent current (20 µA) than MM74HC86MX (2 µA)?

A: The quiescent current specification difference reflects manufacturing variations between Diodes Incorporated and onsemi. The 20 µA maximum specification for 74HC86S14-13 remains within acceptable limits for most digital logic applications. This part compensates with superior propagation delay performance (15ns vs. 20ns) and extended operating temperature range.

Q: Are all substitute parts RoHS3 compliant?

A: All recommended active substitute parts (MC74HC86ADG, MC74HC86ADR2G, 74HC86S14-13, CD74HC86M96, 74HC86D,653, 74HC86D-Q100,118, CD74HC86MT, and SN74HC86D) are RoHS3 compliant. Compliance status is critical for applications subject to environmental regulations.

Q: What packaging formats are available for 74HC86 XOR logic gates?

A: Available packaging formats include Tape & Reel (TR), Tube, Cut Tape (CT) & Digi-Reel®, and unspecified formats. All parts maintain the 14-SOIC (0.154", 3.90mm Width) physical form factor. Select packaging based on production volume and assembly requirements: Tape & Reel for high-volume automated assembly, Tube for lower volumes or manual handling.

Q: Can I substitute MM74HC86MX in applications requiring -55°C minimum operating temperature?

A: No. MM74HC86MX operates from -40°C minimum. For applications requiring -55°C operation, select MC74HC86ADG, MC74HC86ADR2G, CD74HC86M96, CD74HC86M, or CD74HC86MT, all of which specify -55°C minimum operating temperature.
