Engineering Selection Recommendations

For new designs and production continuity, SN74ABT652ADWR is the primary recommended substitute. This part is manufactured by Texas Instruments, maintains active product status, and is available in Tape & Reel packaging with the highest inventory level (4823 Pcs). All electrical and mechanical parameters are identical to the 74ABT652AD,112, and the part carries ROHS3 compliance and REACH Unaffected certification.

SN74ABT652ADW serves as a secondary option for applications where Tube packaging is acceptable. This part is also in active production status with 1239 Pcs available.

SN74ABT543ADW, SN74ABT646ADW, SN74ABT646DW, and SN74ABT657ADW are parametric equivalents with identical electrical specifications and package dimensions. These parts differ only in base product number designation but maintain full functional compatibility. All are in active production status with adequate inventory levels.

SN74ABT652DWR is listed as discontinued at DiGi Electronics and should be considered only when other active alternatives are unavailable.

Frequently Asked Questions (FAQ)

Q: Can SN74ABT652ADWR directly replace 74ABT652AD,112 in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters: 8-bit non-inverting transceiver, 3-state output, 4.5V–5.5V supply, -40°C to 85°C operating range, and 24-SOIC package. The only difference is packaging format (Tape & Reel vs. unspecified original packaging).

Q: What is the difference between SN74ABT652ADW and SN74ABT652ADWR?

A: Both parts are identical electrically and mechanically. The difference is packaging: SN74ABT652ADW is supplied in Tube format, while SN74ABT652ADWR is supplied in Tape & Reel (TR) format. Selection depends on assembly process requirements.

Q: Are SN74ABT543ADW, SN74ABT646ADW, and SN74ABT657ADW true equivalents?
