Engineering Selection Recommendations

Primary Recommendation: SN74AC86DR

The SN74AC86DR is the direct Texas Instruments equivalent with identical electrical specifications and active product status. This part maintains the same quiescent current (2 µA) and is available in Cut Tape and Digi-Reel packaging formats suitable for production environments.

Alternative Selections:

MC74AC86DR2G (onsemi) and MC74AC86DG (onsemi) are manufacturer-recommended alternatives with active status and ROHS3 compliance. These parts accept a maximum quiescent current of 4 µA, which remains within acceptable operating parameters for most applications.

74AC86SCX (Fairchild Semiconductor) and 74AC86SC (Fairchild Semiconductor) are parametric equivalents with active status. These parts maintain identical electrical performance and are available in bulk and unspecified packaging formats.

All substitute parts maintain ROHS3 compliance or equivalent environmental standards where specified. Selection should be based on packaging availability, supply chain requirements, and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can SN74AC86D be replaced with SN74AC86DR?

A: Yes. SN74AC86DR is a direct equivalent with identical electrical specifications, operating temperature range, and 14-SOIC package. The primary difference is packaging format (Cut Tape & Digi-Reel versus Tube).

Q: What is the difference between Texas Instruments and onsemi versions?

A: Texas Instruments (SN74AC86D, SN74AC86DR) and onsemi (MC74AC86DR2G, MC74AC86DG) versions are functionally equivalent. The onsemi variants specify a maximum quiescent current of 4 µA compared to 2 µA for Texas Instruments, but both meet the 74AC86 logic family standard. All other electrical parameters are identical.

Q: Are Fairchild Semiconductor parts (74AC86SCX, 74AC86SC) compatible?

A: Yes. Fairchild Semiconductor 74AC86 parts maintain identical logic function, pin configuration, and electrical performance. They are parametric equivalents suitable for direct substitution in the 14-SOIC package.

Q: Does packaging format affect electrical performance?

A: No. Packaging format (Tube, Cut Tape, Digi-Reel, Tape & Reel, Bulk) does not affect electrical performance or functional compatibility. Selection should be based on production assembly requirements and supply chain logistics.

Q: Are all substitute parts ROHS3 compliant?

A: Texas Instruments and onsemi parts are specified as ROHS3 compliant. Fairchild Semiconductor parts do not specify RoHS status in the provided data. Verify compliance requirements with your procurement or quality assurance department if RoHS certification is mandatory.

Q: Can I mix manufacturers in the same design?

A: Yes. All listed parts are functionally and mechanically equivalent and can be used interchangeably within the same circuit design. Pin configuration and electrical performance are identical across all manufacturers.
