74VHC86MX XOR Logic IC Equivalent & Substitute Parts

Part Overview

The 74VHC86MX is a 4-channel, 2-input XOR (Exclusive OR) logic gate IC manufactured by onsemi in a 14-SOIC surface mount package. This part is currently obsolete, making substitute components necessary for new designs or production continuity. The 74VHC86 series provides fundamental logic gating functionality across a wide supply voltage range of 2V to 5.5V, suitable for general-purpose digital logic applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the 74VHC86MX is determined by the following critical parameters:

• Logic function: XOR gate with 4 channels and 2 inputs per channel
• Supply voltage range: 2V ~ 5.5V minimum compatibility
• Output drive capability: 8mA minimum for both high and low states
• Propagation delay: 8.8ns maximum at 5V with 50pF load
• Package type: 14-SOIC surface mount configuration
• Electrical characteristics: Input logic levels, quiescent current, and thermal operating range

Substitute parts are grouped into three categories based on their relationship to the main part:

Similar Parts (Same Manufacturer): MC74VHC86DR2G and SN74AHC86NSR maintain identical or superior electrical specifications with compatible packaging.

Direct Substitutes (Different Manufacturers): SN74AHC86D and SN74AHC86DR from Texas Instruments provide equivalent functionality with extended operating temperature ranges.

Upgrade Options: 74AHC86D,118 (NXP Semiconductors) and 74AHC86D-Q100J (Nexperia USA Inc.) offer enhanced specifications or automotive-grade qualification.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Preferred): MC74VHC86DR2G from onsemi is the primary substitute, offering identical electrical specifications with active product status and extended operating temperature range (-55°C ~ 125°C). This part maintains the same 14-SOIC package footprint and is available in Tape & Reel packaging.

For Multi-Source Strategy: SN74AHC86DR from Texas Instruments provides an active, directly compatible alternative with identical electrical performance and the same Cut Tape & Digi-Reel packaging format as the original 74VHC86MX. This part ensures supply chain flexibility.

For Extended Temperature Applications: Both MC74VHC86DR2G and SN74AHC86DR support operating temperatures up to 125°C, compared to the original part's 85°C maximum, providing thermal margin for demanding environments.

For Automotive Applications: 74AHC86D-Q100J from Nexperia USA Inc. is qualified to AEC-Q100 automotive standards with active product status. This option is suitable for automotive-grade designs requiring formal qualification documentation.

Packaging Consideration: SN74AHC86NSR uses a wider 14-SOIC package (0.209" vs. 0.154" width). Verify PCB layout compatibility before selection, as this part may not fit existing footprints designed for the narrower 0.154" package.

Frequently Asked Questions (FAQ)

Q: Can I use SN74AHC86NSR as a direct drop-in replacement for 74VHC86MX?

A: SN74AHC86NSR is electrically equivalent but uses a wider 14-SOIC package (0.209" width versus 0.154" width). PCB footprint compatibility must be verified. If your design uses the narrower footprint, MC74VHC86DR2G or SN74AHC86DR are preferred options.

Q: What is the difference between the 74VHC and 74AHC series?

A: Both series provide identical XOR logic functionality with the same electrical specifications for this application. The primary difference is manufacturer and product status. 74AHC variants from Texas Instruments and Nexperia are currently active products, while the 74VHC86MX is obsolete.

Q: Is the 74AHC86D,118 from NXP Semiconductors a suitable replacement?

A: Yes, 74AHC86D,118 is electrically compatible and maintains active product status. However, limited parameter data is provided for this part. Consult the manufacturer datasheet to confirm all specifications match your application requirements before design implementation.

Q: Why do some substitute parts have extended operating temperature ranges?

A: Substitute parts like MC74VHC86DR2G and SN74AHC86DR support -55°C to 125°C operation, compared to the original 74VHC86MX range of -40°C to 85°C. These extended ranges provide additional thermal margin and are suitable for industrial and automotive applications without requiring design changes.

Q: Are all substitute parts RoHS3 compliant?

A: Yes, all listed substitute parts are ROHS3 compliant with MSL rating of 1 (Unlimited), matching the environmental and regulatory compliance of the original 74VHC86MX.

Q: Which substitute offers the best long-term availability?

A: SN74AHC86DR from Texas Instruments and MC74VHC86DR2G from onsemi both have active product status with substantial inventory levels (3350 and 1731 units respectively), providing reliable long-term sourcing options.
