Engineering Selection Recommendations

For new designs and procurement, Texas Instruments SN74ABT series parts with Active product status are the primary selection path. SN74ABT16652DLR, SN74ABT16657DLR, and SN74ABT16952DLR offer the highest inventory availability and long-term supply assurance. All active substitutes carry ROHS3 compliance and REACH Unaffected status, meeting modern regulatory requirements.

The onsemi 74ABT16652CSSCX and Texas Instruments 74FCT series parts (CY74FCT16652ATPVCT, CY74FCT16543CTPVCT, CY74FCT16646CTPVCT) are classified as obsolete or discontinued, limiting their suitability for new production. These parts remain available in current inventory but should be reserved for legacy system maintenance and repair applications.

SN74ABT16470DLR is discontinued at DiGi Electronics and should be considered a secondary option when primary active substitutes are unavailable.

Frequently Asked Questions (FAQ)

Q: Can I substitute any of these parts interchangeably in my design?

A: Yes. All listed substitute parts meet identical electrical parameters (logic type, element count, bit width, output type, current ratings, supply voltage, and temperature range) and share the same 56-BSSOP package footprint. Pin-for-pin compatibility is maintained across all substitutes.

Q: What is the difference between the 74ABT and 74FCT series parts?

A: Both series meet the same electrical and mechanical specifications for this application. The 74FCT series parts are obsolete, while 74ABT series parts from Texas Instruments remain in active production. For new designs, select from the active 74ABT series.

Q: Why are there multiple part numbers with similar names (16652, 16543, 16646, 16657, 16952)?

A: These represent different internal logic configurations within the same transceiver family. All variants meet the specified electrical parameters and package requirements, making them functionally equivalent for applications requiring a 2-element, 8-bit non-inverting transceiver with 3-state output.

Q: Does packaging type (Tube, Tape & Reel, Cut Tape) affect electrical performance?

A: No. Packaging type affects only handling, storage, and assembly processes. Electrical performance and pin compatibility remain identical regardless of packaging format.

Q: Are all substitutes RoHS compliant?

A: Active Texas Instruments substitutes carry ROHS3 compliance. The onsemi original part and obsolete 74FCT series parts do not list RoHS status in the provided specifications. Verify RoHS compliance requirements with your procurement or quality department before selecting obsolete alternatives.
