Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74ALS153SJ is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 2 x 4:1 multiplexer topology
• Package type: 16-SOIC surface mount package with 0.209" width (5.30mm)
• Voltage supply range: 4.5V to 5.5V single supply
• Output current specifications: 2.6mA high, 24mA low
• Operating temperature range: 0°C to 70°C
• Base product series: 74ALS logic family

The SN74ALS153NSR from Texas Instruments meets all these electrical and mechanical parameters, establishing it as a direct functional equivalent. Both parts share identical circuit topology, pinout, electrical performance characteristics, and package dimensions, enabling pin-for-pin substitution in applications currently using the DM74ALS153SJ.

Engineering Selection Recommendations

The SN74ALS153NSR is the qualified substitute for the obsolete DM74ALS153SJ. Selection between these parts should be based on the following factors:

Product Status: The DM74ALS153SJ carries obsolete status, indicating discontinued manufacturing and limited availability. The SN74ALS153NSR maintains active product status with established supply channels and ongoing manufacturing support from Texas Instruments.

Compliance & Certifications: Both parts share identical REACH, ECCN, and HTSUS classifications, ensuring equivalent regulatory compliance. The SN74ALS153NSR carries RoHS3 compliance certification, providing additional environmental compliance assurance for new designs.

Availability & Supply: The SN74ALS153NSR demonstrates superior inventory availability (3200 pcs) compared to the DM74ALS153SJ (1109 pcs), supporting production continuity and supply chain reliability.

Packaging: The SN74ALS153NSR is supplied in Tape & Reel (TR) format, standard for automated assembly processes, whereas the DM74ALS153SJ packaging format is not specified. This distinction may influence procurement and assembly workflow decisions.

For new designs and production transitions, the SN74ALS153NSR is the appropriate selection. For legacy system maintenance requiring exact part matching, the DM74ALS153SJ remains available in limited quantities while stock exists.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS153NSR directly replace the DM74ALS153SJ in existing designs?

A: Yes. Both parts are pin-for-pin equivalents with identical electrical specifications, package dimensions, and circuit topology. No design modifications are required for substitution.

Q: Are there differences in the package format between these parts?

A: Both parts use the 16-SOIC package with 0.209" width (5.30mm). The primary difference is packaging format: the SN74ALS153NSR is supplied in Tape & Reel format for automated assembly, while the DM74ALS153SJ packaging format is not specified in the available data.

Q: What is the significance of the obsolete status for the DM74ALS153SJ?

A: Obsolete status indicates the manufacturer has discontinued production. This affects long-term availability and supply reliability. The SN74ALS153NSR, with active status, provides assured supply for ongoing production requirements.
