74AC86SC XOR Logic IC Equivalent & Substitute Parts

Part Overview

The 74AC86SC is a 4-channel, 2-input XOR (Exclusive OR) logic integrated circuit manufactured by onsemi in 14-SOIC surface mount packaging. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The 74AC86 series represents a standard logic function across multiple manufacturers, with several active alternatives available that maintain functional and electrical compatibility.

Substitute Part Grouping Explanation

Substitution for the 74AC86SC is determined by strict equivalence across the following critical parameters:

Logic function: 4-channel, 2-input XOR gate
Voltage supply range: 2V ~ 6V minimum
Output drive capability: 24mA minimum
Propagation delay: 8.5ns maximum @ 5V, 50pF
Package type: 14-SOIC surface mount
Operating temperature range: -40°C ~ 85°C minimum

Substitute parts are grouped into two categories:

Direct Manufacturer Equivalents maintain identical electrical specifications and packaging, differing only in product status or packaging format (Tube vs. Tape & Reel).

Parametric Equivalents meet all functional and electrical requirements but may have extended voltage ranges, lower quiescent current, or different product status. These parts are fully interchangeable in circuit operation.

Engineering Selection Recommendations

For direct replacement of the obsolete 74AC86SC, select from parts with matching electrical specifications and active product status:

Primary Recommendation: MC74AC86DG (onsemi) or SN74AC86DR (Texas Instruments) provide identical functional performance with active availability. MC74AC86DG maintains the same Tube packaging format as the original part. SN74AC86DR offers Cut Tape & Digi-Reel packaging suitable for automated assembly.

Alternative with Extended Specifications: CD74AC86M96 (Texas Instruments) extends the voltage supply range to 1.5V ~ 5.5V and operating temperature to -55°C ~ 125°C, providing broader application flexibility. This part carries ROHS3 compliance and active product status.

Packaging Consideration: SN74AC86NSR provides identical electrical performance in Tape & Reel packaging with active status, suitable for high-volume production environments.

Avoid CD74AC86M (Harris Corporation) due to obsolete status and RoHS non-compliance, despite parametric equivalence.

Frequently Asked Questions (FAQ)

Q: Can MC74AC86DR2G replace 74AC86SC directly? A: Yes. MC74AC86DR2G is a direct onsemi equivalent with identical voltage supply range, propagation delay, and operating temperature. The only difference is packaging format (Tape & Reel vs. Tube) and slightly higher quiescent current (4 µA vs. 2 µA), which is operationally insignificant.

Q: What is the difference between MC74AC86DG and MC74AC86DR2G? A: Both are onsemi 74AC86 variants with identical electrical specifications. MC74AC86DG uses Tube packaging; MC74AC86DR2G uses Tape & Reel packaging. Select based on assembly process requirements.

Q: Is CD74AC86M96 compatible with 74AC86SC? A: CD74AC86M96 is functionally compatible but operates with extended voltage range (1.5V ~ 5.5V vs. 2V ~ 6V) and slower propagation delay (10.8ns vs. 8.5ns). Use only if your circuit tolerates these parameter variations.

Q: Why is SN74AC86D listed as discontinued? A: SN74AC86D is discontinued at DiGi Electronics but remains a valid parametric equivalent. Verify availability through alternative distributors before design commitment.

Q: What packaging format should I select for new designs? A: For automated surface mount assembly, select Tape & Reel packaging (MC74AC86DR2G or SN74AC86DR). For manual assembly or lower volumes, Tube packaging (MC74AC86DG) is acceptable.

Q: Are all substitute parts RoHS3 compliant? A: All recommended substitutes except CD74AC86M are ROHS3 compliant. CD74AC86M is RoHS non-compliant and should be avoided for new designs subject to RoHS requirements.
