Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, SN74ALS153DR and SN74ALS253DR are the preferred substitutes due to their active product status and ROHS3 compliance. Both parts are available in Tape & Reel packaging, which is standard for high-volume manufacturing.

SN74ALS253D is available as a Last Time Buy option from Texas Instruments and is supplied in Tube packaging, suitable for lower-volume applications or prototype work.

All three substitute parts maintain full electrical and mechanical compatibility with the DM74ALS253MX and operate within identical voltage supply and temperature ranges.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS253DR be used as a direct replacement for DM74ALS253MX?

A: Yes. Both parts share identical circuit configuration (2 x 4:1 multiplexer), package type (16-SOIC), voltage supply range (4.5V ~ 5.5V), output current specifications (2.6mA, 24mA), and operating temperature range (0°C ~ 70°C). The parts are electrically and mechanically interchangeable.

Q: What is the difference between SN74ALS253DR and SN74ALS153DR?

A: Both parts are functionally equivalent 2 x 4:1 multiplexers with identical electrical specifications and package type. The primary difference is the base product number designation (74ALS253 versus 74ALS153). Both are suitable substitutes for the DM74ALS253MX.

Q: Why is the DM74ALS253MX listed as obsolete?

A: The DM74ALS253MX has reached end-of-life status with onsemi. Texas Instruments continues to manufacture equivalent parts under the 74ALS series, ensuring continued availability of this multiplexer function.

Q: Does packaging format affect electrical performance?

A: No. Tube and Tape & Reel packaging formats contain identical components. Packaging selection is based on manufacturing volume and handling requirements, not electrical characteristics.

Q: Are the substitute parts RoHS compliant?

A: Yes. SN74ALS253D, SN74ALS153DR, and SN74ALS253DR are all ROHS3 compliant, meeting environmental and regulatory requirements for modern electronics manufacturing.
