Substitute Part Grouping Explanation

Substitute parts for the DM74ALS1004MX are qualified based on the following criteria:

Electrical Compatibility: All substitute parts must maintain identical logic type (Inverter), circuit count (6 channels), input count (1 input per channel), supply voltage range (4.5V ~ 5.5V), output current specifications (15mA high, 24mA low), input logic levels (0.8V low, 2V high), and propagation delay (7ns @ 5V, 50pF).

Mechanical Compatibility: All substitute parts must use surface mount technology with compatible 14-pin SOIC packaging. Package width variations (0.154" vs 0.209") are acceptable as both conform to 14-SOIC standard dimensions.

Series Compliance: All parts belong to the 74ALS logic family, ensuring functional and electrical interchangeability.

The DM74ALS1004MX has two qualified substitutes from Texas Instruments: SN74ALS1004D and SN74ALS1004NSR. Both maintain full electrical equivalence while offering active product status and improved compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

SN74ALS1004D (Texas Instruments) is the primary substitute for the DM74ALS1004MX. This part maintains identical electrical specifications and package dimensions (0.154", 3.90mm width). The SN74ALS1004D carries active product status and ROHS3 compliance, providing long-term availability and regulatory alignment for new designs.

SN74ALS1004NSR (Texas Instruments) is a secondary substitute with identical electrical performance. This part differs in package width (0.209", 5.30mm) and is supplied in tape and reel format. The SN74ALS1004NSR is suitable for high-volume production environments where tape and reel packaging is standard. ROHS3 compliance and active status ensure regulatory compliance and supply continuity.

Both Texas Instruments substitutes provide superior compliance certifications compared to the obsolete onsemi part, making them the recommended choices for new designs and production transitions.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS1004D and SN74ALS1004NSR be used interchangeably with DM74ALS1004MX?

A: Yes. Both Texas Instruments parts maintain identical electrical specifications, logic function, and pin configuration. The primary difference is packaging format and supplier device package designation. Both are direct functional equivalents.

Q: What is the difference between SN74ALS1004D and SN74ALS1004NSR?

A: Both parts are electrically identical. The SN74ALS1004D is supplied in tube packaging, while the SN74ALS1004NSR is supplied in cut tape and Digi-Reel format. The package case width differs: SN74ALS1004D is 0.154" (3.90mm), and SN74ALS1004NSR is 0.209" (5.30mm). Both conform to 14-SOIC standard dimensions and are mechanically compatible with 14-SOIC footprints.

Q: Why is the DM74ALS1004MX obsolete?

A: The DM74ALS1004MX is classified as obsolete by onsemi. Texas Instruments continues to manufacture equivalent 74ALS1004 inverter ICs in active production status, making their parts the recommended alternatives for ongoing supply.

Q: Are there any compliance differences between the substitute parts?

A: Both Texas Instruments substitutes (SN74ALS1004D and SN74ALS1004NSR) are ROHS3 compliant and REACH unaffected. The original DM74ALS1004MX does not specify RoHS status. The Texas Instruments parts provide enhanced regulatory compliance for applications requiring ROHS3 certification.

Q: Can I use these parts in existing designs without PCB modifications?

A: Yes. Both substitute parts use identical pin configurations and 14-SOIC surface mount packages. Existing PCB designs and footprints are compatible. The package width variation between SN74ALS1004D (0.154") and SN74ALS1004NSR (0.209") does not affect PCB compatibility, as both fit standard 14-SOIC footprints.
