Substitute Part Grouping Explanation

Substitute parts for the DM74AS30MX are identified based on strict parametric equivalence across the following criteria:

• Logic Type: NAND Gate with identical 1 channel, 8 input configuration
• Electrical Specifications: Matching voltage supply range (4.5V ~ 5.5V), output current ratings (2mA, 20mA), input logic levels (0.8V low, 2V high), and propagation delay (5ns @ 5V, 50pF)
• Package Compatibility: 14-SOIC surface mount package with identical physical dimensions (0.154", 3.90mm Width)
• Operating Temperature Range: 0°C ~ 70°C
• Series Classification: 74AS logic family

All identified substitutes maintain these parameters without deviation, ensuring functional and mechanical interchangeability.

Parameter Comparison

Engineering Selection Recommendations

Both SN74AS30D and SN74AS30DR from Texas Instruments are parametrically equivalent to the DM74AS30MX and serve as direct substitutes. The primary distinction between these alternatives is packaging format:

• SN74AS30D: Standard packaging configuration
• SN74AS30DR: Tape & Reel (TR) packaging for automated assembly processes

Both substitute parts are classified as Active products with ROHS3 compliance, providing superior long-term availability and regulatory alignment compared to the obsolete DM74AS30MX. Selection between SN74AS30D and SN74AS30DR should be based on procurement and assembly requirements rather than electrical or functional considerations, as all electrical parameters and operating characteristics remain identical.

Frequently Asked Questions (FAQ)

Q: Can SN74AS30D and SN74AS30DR be used interchangeably with DM74AS30MX?

A: Yes. Both Texas Instruments parts are parametrically equivalent across all electrical specifications, logic function, operating temperature range, and 14-SOIC package dimensions. They are direct substitutes.

Q: What is the difference between SN74AS30D and SN74AS30DR?

A: The primary difference is packaging format. SN74AS30D uses standard packaging, while SN74AS30DR is supplied in Tape & Reel format optimized for automated pick-and-place assembly. Electrical and functional characteristics are identical.

Q: Why is the DM74AS30MX classified as obsolete?

A: The DM74AS30MX is listed as obsolete by onsemi. Active alternatives from Texas Instruments ensure continued availability and support for new designs and production runs.

Q: Are there any compliance differences between the main part and substitutes?

A: Yes. The substitute parts SN74AS30D and SN74AS30DR are ROHS3 compliant, whereas the DM74AS30MX compliance status is not specified. Both substitutes maintain REACH Unaffected status consistent with the original part.

Q: Do the substitute parts maintain the same 14-SOIC package dimensions?

A: Yes. All parts, including SN74AS30D and SN74AS30DR, use the 14-SOIC package with identical physical dimensions of 0.154" width and 3.90mm width specification, ensuring mechanical compatibility in existing PCB layouts.
