74VHC86M XOR Logic IC Equivalent & Substitute Parts

Part Overview

The 74VHC86M is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by onsemi in a 14-SOIC surface mount package. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity. The 74VHC86M operates across a 2V to 5.5V supply voltage range with low quiescent current and standard TTL-compatible logic levels, making it suitable for general-purpose digital logic applications requiring XOR gate functionality.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 74VHC86M is determined by the following critical parameters: logic type (XOR with 4 channels and 2 inputs per channel), supply voltage range (2V ~ 5.5V minimum), output drive capability (8mA minimum), propagation delay (8.8ns maximum at 5V, 50pF), and package compatibility (14-SOIC form factor). All substitute parts listed maintain these core electrical specifications and physical packaging requirements, ensuring functional and mechanical interchangeability within the specified operating conditions.

The substitute parts are categorized as follows:

Direct Substitutes (Electrical & Mechanical Equivalence): SN74AHC86D, SN74AHC86DR, and 74AHC86D,118 maintain identical logic functionality, electrical performance, and 14-SOIC packaging.

Upgrade Substitutes (Enhanced Specifications): 74AHC86D-Q100J provides automotive-grade qualification (AEC-Q100) with extended operating temperature range (-40°C ~ 125°C) and identical electrical performance.

Similar Substitutes (Package Variant): SN74AHC86NSR maintains electrical equivalence but uses a wider 14-SO package (0.209", 5.30mm Width) requiring PCB layout verification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Pin-Compatible, Same Package): SN74AHC86DR is the primary recommendation. This part is manufactured by Texas Instruments, maintains active product status, and is available in standard Cut Tape and Digi-Reel packaging formats. It provides identical electrical performance and 14-SOIC packaging (0.154", 3.90mm Width) with no PCB layout modifications required.

For Extended Temperature Applications: 74AHC86D-Q100J, manufactured by Nexperia USA Inc., is suitable when automotive-grade qualification (AEC-Q100) and extended operating temperature range (-40°C ~ 125°C) are required. This part maintains the standard 14-SOIC package footprint and is actively produced.

For High-Volume Procurement: 74AHC86D,118 from NXP Semiconductors offers the largest available inventory (19,230 pcs) and active product status, suitable for applications where supply chain continuity is prioritized.

Package Variant Consideration: SN74AHC86NSR uses a wider 14-SO package (0.209", 5.30mm Width) and requires PCB layout verification before implementation. This part is suitable only when the wider package footprint is compatible with existing board designs.

Frequently Asked Questions (FAQ)

Q: Can SN74AHC86DR be used as a direct replacement for 74VHC86M without PCB modifications?

A: Yes. SN74AHC86DR maintains identical pin configuration, electrical specifications, and 14-SOIC package dimensions (0.154", 3.90mm Width). No PCB layout changes are required for direct substitution.

Q: What is the difference between the 74AHC86 series and the original 74VHC86M?

A: Both are 4-channel, 2-input XOR logic gates with identical supply voltage range (2V ~ 5.5V), quiescent current (2 µA max), output drive (8mA), and propagation delay (8.8ns @ 5V, 50pF). The primary difference is product status: 74VHC86M is obsolete, while 74AHC86 variants are actively manufactured by multiple suppliers.

Q: Is the SN74AHC86NSR compatible with the original 74VHC86M footprint?

A: No. SN74AHC86NSR uses a wider 14-SO package (0.209", 5.30mm Width) compared to the standard 14-SOIC (0.154", 3.90mm Width). PCB layout verification is required before implementation.

Q: Which substitute part has the longest operating temperature range?

A: SN74AHC86D, SN74AHC86DR, 74AHC86D-Q100J, and SN74AHC86NSR all support -40°C ~ 125°C operating temperature, compared to the original 74VHC86M specification of -40°C ~ 85°C.

Q: Are all substitute parts RoHS3 compliant?

A: SN74AHC86D, SN74AHC86DR, 74AHC86D-Q100J, and SN74AHC86NSR are confirmed ROHS3 compliant. Compliance status for 74AHC86D,118 is not specified in available documentation.

Q: What packaging formats are available for the recommended substitute SN74AHC86DR?

A: SN74AHC86DR is available in Cut Tape (CT) and Digi-Reel packaging formats, suitable for both manual assembly and automated pick-and-place operations.
