Engineering Selection Recommendations

All five substitute parts are parametrically equivalent to the 74ABT652CMSAX and maintain identical electrical and mechanical specifications. The primary selection criteria are based on product status and compliance certifications:

All Texas Instruments alternatives (SN74ABT543ADBR, SN74ABT646ADBR, SN74ABT646DBR, SN74ABT652ADBR, SN74ABT657ADBR) are classified as Active products with ROHS3 compliance certification. These parts are suitable for new designs and ongoing production applications where compliance with current environmental regulations is required.

The SN74ABT652ADBR represents the closest functional equivalent, maintaining the identical base product number (74ABT652) while offering active product status and ROHS3 compliance. Current inventory levels across all substitutes support immediate procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can the 74ABT652CMSAX be directly replaced with any of the listed substitutes?

A: Yes. All listed substitutes maintain identical electrical specifications (voltage supply, output current, operating temperature) and mechanical specifications (24-SSOP package, surface mount configuration). Direct pin-for-pin replacement is supported without circuit modification.

Q: What is the difference between the various Texas Instruments substitutes?

A: The substitutes differ only in their base product numbers (543, 646, 652, 657), which reflect different internal logic configurations. All maintain identical electrical and mechanical parameters specified for the 74ABT652CMSAX. Selection among these alternatives depends on specific application requirements and internal functional differences not specified in the parametric data.

Q: Why is the original 74ABT652CMSAX classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The listed Texas Instruments alternatives provide active product continuity with equivalent electrical and mechanical performance.

Q: Are there any compliance differences between the original and substitute parts?

A: The Texas Instruments substitutes carry ROHS3 compliance certification, whereas the original onsemi part does not specify RoHS status. All parts maintain identical REACH Unaffected and EAR99 ECCN classifications.

Q: What packaging format is available for these substitutes?

A: All substitutes are supplied in Tape & Reel (TR) packaging format, suitable for automated assembly processes. The physical package remains 24-SSOP with identical 0.209" width and 5.30mm dimensions.
