Substitute Part Grouping Explanation

Substitution for the DM74AS00MX is determined by strict equivalence across the following parameters:

• Logic Type: NAND Gate (4 channels, 2 inputs per channel)
• Voltage Supply Range: 4.5V ~ 5.5V
• Output Current Specifications: 2mA (high), 20mA (low)
• Input Logic Levels: 0.8V (low), 2V (high)
• Propagation Delay: 4.5ns @ 5V, 50pF
• Operating Temperature Range: 0°C ~ 70°C
• Package: 14-SOIC surface mount

The identified substitute parts maintain identical electrical characteristics and mechanical compatibility, differing only in manufacturer, product status, and packaging format (tube versus tape & reel).

Parameter Comparison

Engineering Selection Recommendations

For new designs and production applications, SN74AS00DR (Texas Instruments) is the primary substitute. This part maintains active product status, ensuring long-term availability and supply chain stability. It carries ROHS3 compliance certification and is supplied in tape & reel format, standard for automated assembly operations.

SN74AS00D (Texas Instruments) serves as a secondary substitute option, available in tube packaging. This part is designated Last Time Buy status, indicating limited future availability.

Both Texas Instruments substitutes are electrically and mechanically equivalent to the DM74AS00MX across all specified parameters, with identical pin configuration, electrical performance, and thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can SN74AS00DR replace DM74AS00MX in existing designs? A: Yes. Both parts are electrically and mechanically identical across all specified parameters. Pin configuration, voltage supply range, output current, propagation delay, and operating temperature are equivalent. Direct substitution is possible without circuit modification.

Q: What is the difference between SN74AS00D and SN74AS00DR? A: Both parts are electrically identical. The primary difference is packaging format: SN74AS00D is supplied in tube packaging, while SN74AS00DR is supplied in tape & reel format. Tape & reel is standard for high-volume automated assembly. SN74AS00DR also maintains active product status, while SN74AS00D is Last Time Buy.

Q: Why is the DM74AS00MX obsolete? A: The DM74AS00MX is classified as obsolete by the manufacturer. Substitute parts from Texas Instruments (SN74AS00D and SN74AS00DR) provide equivalent functionality and are actively supported.

Q: Are there any compliance differences between these parts? A: SN74AS00D and SN74AS00DR both carry ROHS3 compliance certification. All three parts have MSL rating of 1 (Unlimited) and REACH Unaffected status. Compliance certifications are equivalent across all substitutes.

Q: What is the 14-SOIC package specification? A: 14-SOIC refers to a 14-pin Small Outline Integrated Circuit package with 0.154 inches (3.90mm) width. This is a surface mount package standard for TTL logic ICs. All three parts use identical package dimensions and pin configuration.

Q: Can these parts be used interchangeably in PCB assembly? A: Yes. All three parts share identical 14-SOIC package specifications, pin configuration, and mounting type (surface mount). PCB footprints and assembly processes are directly compatible.
