Substitute Part Grouping Explanation

Substitute parts for the DM74AS1004AM are qualified based on matching the following critical parameters:

• Logic Type: Inverter
• Number of Circuits: 6
• Number of Inputs: 1
• Voltage - Supply: 4.5V ~ 5.5V
• Current - Output High, Low: 48mA, 48mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 4ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount
• Series: 74AS

Substitutes are categorized as direct equivalents when all electrical and functional parameters match identically. Package variations within the 14-SOIC family and differences in product status or packaging format (tube, tape & reel) do not affect functional interchangeability in circuit applications.

Engineering Selection Recommendations

For applications currently using the DM74AS1004AM, the following selection criteria apply based on product status and compliance:

Primary Selection: SN74AS1004ADR (Texas Instruments) This part maintains active product status with ROHS3 compliance and is available in tape & reel packaging. All electrical parameters and the 14-SOIC (0.154", 3.90mm Width) package match the original specification exactly.

Secondary Selection: SN74AS1004AD (Texas Instruments) This part is classified as Last Time Buy with ROHS3 compliance and is available in tube packaging. Electrical parameters and package dimensions are identical to the primary selection.

Alternative Selection: SN74AS1004ANSR (Texas Instruments) This part maintains active product status with ROHS3 compliance. The package variant is 14-SOIC (0.209", 5.30mm Width), which differs in width from the original specification. This part is functionally equivalent but requires PCB layout verification for physical fit.

Frequently Asked Questions (FAQ)

Q: Can SN74AS1004ADR directly replace DM74AS1004AM in existing designs? A: Yes. All electrical parameters, logic function, and the 14-SOIC (0.154", 3.90mm Width) package are identical. No circuit modifications are required.

Q: What is the difference between SN74AS1004AD and SN74AS1004ADR? A: Both parts are electrically identical. The primary difference is packaging format: SN74AS1004AD is supplied in tube packaging, while SN74AS1004ADR is supplied in tape & reel format. Selection depends on assembly process requirements.

Q: Can SN74AS1004ANSR be used as a substitute? A: SN74AS1004ANSR is functionally equivalent with matching electrical specifications. However, the package width differs (0.209" versus 0.154"). PCB footprint compatibility must be verified before implementation.

Q: Why is the DM74AS1004AM classified as obsolete? A: Obsolete status indicates the part is no longer manufactured by onsemi. Substitute parts from active manufacturers ensure continued availability for production and maintenance applications.

Q: Are all substitute parts ROHS3 compliant? A: Yes. All Texas Instruments substitute parts listed are ROHS3 compliant, meeting current environmental and regulatory requirements.

Q: What is the Moisture Sensitivity Level (MSL) for these parts? A: All parts, including the original and substitutes, have MSL 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage or handling.
