Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74ALS03BM is determined by strict equivalence across the following critical parameters:

• Logic configuration: 4-channel NAND gate with 2 inputs per channel
• Open collector output architecture
• Supply voltage range: 4.5V ~ 5.5V
• Output current capability: 8mA low
• Input logic thresholds: 0.8V low, 2V high
• Propagation delay: 50ns @ 5V, 50pF
• Package type: 14-SOIC surface mount
• Operating temperature range: 0°C ~ 70°C

The substitute parts SN74ALS03BD and SN74ALS03BDR, both manufactured by Texas Instruments, meet all these specifications. Differences exist only in product status and packaging format (tube versus tape & reel), which do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the DM74ALS03BM, the SN74ALS03BDR is the preferred substitute due to its active product status and ROHS3 compliance. This part is manufactured by Texas Instruments and is available in tape & reel packaging, suitable for automated assembly processes.

The SN74ALS03BD serves as an alternative when tape & reel packaging is not required. This part carries last time buy status, indicating limited future availability.

Both Texas Instruments substitutes provide identical electrical performance and mechanical compatibility with the obsolete onsemi part. Selection between SN74ALS03BD and SN74ALS03BDR should be based on packaging requirements and procurement lead times.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS03BD and SN74ALS03BDR be used interchangeably with DM74ALS03BM?

A: Yes. All three parts share identical electrical specifications, logic configuration, and 14-SOIC package dimensions. The only differences are manufacturer, product status, and packaging format (tube versus tape & reel).

Q: What is the difference between SN74ALS03BD and SN74ALS03BDR?

A: Both parts are electrically identical. SN74ALS03BD is supplied in tube packaging, while SN74ALS03BDR is supplied in tape & reel format. SN74ALS03BDR has active product status, whereas SN74ALS03BD is last time buy. For new designs and high-volume production, SN74ALS03BDR is recommended.

Q: Why is the DM74ALS03BM obsolete?

A: The DM74ALS03BM is classified as obsolete by onsemi. Equivalent parts from Texas Instruments remain in active production, ensuring continued availability for replacement and new applications.

Q: Are there any compliance differences between these parts?

A: The Texas Instruments substitutes (SN74ALS03BD and SN74ALS03BDR) are ROHS3 compliant. All three parts are REACH unaffected and carry the same ECCN and HTSUS classifications.

Q: Can these parts be used in new designs?

A: Yes. The SN74ALS03BDR is actively manufactured and suitable for new designs. The SN74ALS03BD should be evaluated for long-term availability due to its last time buy status.
