Substitute Part Grouping Explanation

Substitute parts for the DM74ALS1004M are qualified based on strict electrical and mechanical parameter matching within the 74ALS logic family. The following criteria determine substitution eligibility:

Electrical Parameters (Must Match):

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 15mA, 24mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 7ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters (Must Match):

• Mounting Type: Surface Mount
• Package / Case: 14-SOIC form factor

Identified Substitute Parts:

• SN74ALS1004NSR (Texas Instruments) - Similar manufacturer part with active product status
• SN74ALS1004D (Texas Instruments) - Parametric equivalent with active product status

Both substitutes meet all electrical specifications and operate within identical parameter ranges. Package variations exist in physical dimensions and supplier packaging format but maintain functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

SN74ALS1004NSR (Texas Instruments) is available in active production status with ROHS3 compliance. This part is supplied in Cut Tape and Digi-Reel packaging formats. The package case dimension of 14-SOIC (0.209", 5.30mm Width) differs from the original DM74ALS1004M, requiring PCB layout verification for mechanical fit in existing designs.

SN74ALS1004D (Texas Instruments) is available in active production status with ROHS3 compliance. This part maintains identical package dimensions to the original DM74ALS1004M at 14-SOIC (0.154", 3.90mm Width), providing direct mechanical compatibility. Supplied in Tube packaging format.

Both substitutes provide equivalent electrical performance and meet current regulatory compliance standards. Selection between these options depends on packaging format requirements and PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS1004NSR and SN74ALS1004D be used interchangeably with DM74ALS1004M?

A: Both parts meet all electrical parameter requirements for the DM74ALS1004M. SN74ALS1004D provides direct package dimension compatibility. SN74ALS1004NSR requires verification of PCB layout due to package width variation.

Q: What is the primary difference between SN74ALS1004NSR and SN74ALS1004D?

A: The primary differences are package case dimensions and supplier packaging format. SN74ALS1004NSR uses 14-SOIC (0.209", 5.30mm Width) in Cut Tape/Digi-Reel format. SN74ALS1004D uses 14-SOIC (0.154", 3.90mm Width) in Tube format, matching the original part dimensions.

Q: Are there any compliance or regulatory differences between these substitutes?

A: Both Texas Instruments substitutes are ROHS3 compliant with MSL rating of 1 (Unlimited). The original DM74ALS1004M is REACH Unaffected. All three parts carry identical ECCN and HTSUS classifications.

Q: What parameters must remain constant for substitution eligibility?

A: Logic type, circuit count, input count, supply voltage range, output current ratings, input logic levels, propagation delay, operating temperature range, and mounting type must all match exactly. Package form factor must be 14-SOIC, though physical dimensions may vary.

Q: Why is the DM74ALS1004M classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. Active substitutes from Texas Instruments provide equivalent functionality for ongoing design support and procurement.
