SN74AC86PW XOR Logic IC Equivalent & Substitute Parts

Part Overview

The SN74AC86PW is a 4-channel, 2-input XOR (Exclusive OR) logic gate integrated circuit manufactured by Texas Instruments in 14-TSSOP surface mount packaging. This device operates across a 2V to 6V supply voltage range and is designed for digital logic applications requiring exclusive OR functionality. The SN74AC86PW is currently in Last Time Buy status, making identification of equivalent and substitute parts essential for ongoing design support and procurement planning.

Substitute Part Grouping Explanation

Substitute parts for the SN74AC86PW are classified based on functional and electrical equivalence within the 74AC86 logic family. Substitution is valid when the following criteria are met:

Critical Parameters for Substitution:

• Logic Type: XOR (Exclusive OR)
• Number of Circuits: 4
• Number of Inputs: 2
• Voltage - Supply: 2V ~ 6V
• Package / Case: 14-TSSOP
• Mounting Type: Surface Mount
• Operating Temperature: -40°C ~ 85°C

Substitute parts are grouped into three categories:

MFR Recommended Substitutes: Parts recommended by the original manufacturer with identical electrical specifications and active product status.

Direct Manufacturer Substitutes: Parts from alternative manufacturers meeting all critical electrical and mechanical parameters.

Parametric Equivalents: Parts with the same base product number and logic function, suitable for applications where packaging format flexibility is acceptable.

Parameter Comparison

Engineering Selection Recommendations

For Direct Pin-Compatible Replacement:

SN74AC86PWR is the primary substitute for SN74AC86PW. Both are manufactured by Texas Instruments with identical electrical specifications, operating parameters, and compliance certifications. The only difference is packaging format: SN74AC86PWR is supplied in Tape & Reel format instead of Tube. This part maintains Active product status, ensuring long-term availability and supply chain stability.

For Alternative Manufacturer Sourcing:

MC74AC86DTR2G (onsemi) and 74AC86MTCX (Fairchild Semiconductor) are functionally equivalent alternatives. Both maintain the 14-TSSOP package, identical logic specifications, and operating temperature range. MC74AC86DTR2G has a maximum quiescent current of 4 µA compared to 2 µA for the original part, which is within acceptable tolerance for most applications. Both alternatives are in Active product status.

For Flexible Packaging Requirements:

74AC86MTC (Fairchild Semiconductor) provides parametric equivalence with the same base product number and logic function. This part is available in Bulk packaging format and maintains Active product status. Detailed electrical specifications are not provided for this variant; verification against application requirements is necessary before selection.

Compliance Considerations:

All recommended substitutes maintain ROHS3 compliance and MSL Level 1 rating where specified. Parts selected should align with your design's environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can I use SN74AC86PWR as a direct replacement for SN74AC86PW?

A: Yes. SN74AC86PWR is electrically and functionally identical to SN74AC86PW. The difference is packaging format: SN74AC86PWR is supplied in Tape & Reel format while SN74AC86PW is supplied in Tube format. Both are manufactured by Texas Instruments with identical electrical specifications and compliance certifications.

Q: What is the difference between the substitute parts?

A: SN74AC86PWR and MC74AC86DTR2G are fully equivalent with identical electrical parameters. 74AC86MTCX is also equivalent but manufacturer specifications are not fully detailed. 74AC86MTC is a parametric equivalent with the same logic function but incomplete specification data. All maintain the 14-TSSOP package and -40°C to 85°C operating temperature range.

Q: Does the quiescent current difference in MC74AC86DTR2G affect compatibility?

A: MC74AC86DTR2G has a maximum quiescent current of 4 µA compared to 2 µA for SN74AC86PW. This difference is within acceptable tolerance for most digital logic applications and does not affect functional compatibility or logic operation.

Q: Are all substitutes available in the same package?

A: Yes. All substitute parts listed are available in 14-TSSOP surface mount packaging with identical pin configuration and mechanical dimensions (0.173", 4.40mm Width). Packaging format (Tube, Tape & Reel, or Bulk) differs but the physical component package is identical.

Q: Which substitute should I select for new designs?

A: SN74AC86PWR is recommended for new designs as it maintains Active product status from the original manufacturer (Texas Instruments) with identical specifications. MC74AC86DTR2G from onsemi is an acceptable alternative if supply constraints exist.

Q: Why is the original SN74AC86PW in Last Time Buy status?

A: Last Time Buy status indicates the manufacturer is discontinuing this product. Existing inventory is available but no future production is planned. Substitution to an Active product variant (such as SN74AC86PWR) is recommended for long-term design support and supply chain continuity.
