Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74AS04N is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter (6-channel, single input per channel)
• Electrical Specifications: Supply voltage 4.5V ~ 5.5V, output current 2mA/20mA, input logic levels 0.8V/2V, propagation delay 5ns @ 5V with 50pF load
• Operating Temperature Range: 0°C ~ 70°C
• Package Configuration: 14-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Series Classification: 74AS logic family

The SN74AS04N from Texas Instruments meets all these parameters and is therefore a parametric equivalent. Both parts share identical electrical characteristics, logic functionality, and physical package dimensions, enabling direct substitution in applications requiring 6-channel inverter logic.

Parameter Comparison

Engineering Selection Recommendations

The SN74AS04N is the appropriate substitute for the obsolete DM74AS04N. Both components are classified under the same ECCN (EAR99) and HTSUS codes, and both maintain REACH Unaffected status. The SN74AS04N carries Active product status, ensuring continued availability and supply chain reliability. All electrical parameters, logic functionality, and physical package specifications are identical, supporting direct pin-for-pin replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS04N replace the DM74AS04N in existing designs?

A: Yes. The SN74AS04N is a parametric equivalent with identical electrical specifications, logic configuration, and 14-DIP package dimensions. Direct substitution is supported without design changes.

Q: Are there differences in package handling or storage?

A: The DM74AS04N has Moisture Sensitivity Level (MSL) 1 (Unlimited), while the SN74AS04N lists MSL as Not Applicable. Both are suitable for standard through-hole assembly processes. Verify storage and handling procedures with your supplier for the specific lot.

Q: What is the significance of the Active versus Obsolete product status?

A: The DM74AS04N is obsolete, meaning onsemi no longer manufactures or supports this part. The SN74AS04N is Active, indicating Texas Instruments continues production and supply. For new designs or ongoing procurement, the SN74AS04N is the recommended choice.

Q: Are regulatory certifications equivalent between these parts?

A: Yes. Both parts share identical REACH Status (REACH Unaffected), ECCN (EAR99), and HTSUS (8542.39.0001) classifications, ensuring equivalent regulatory compliance.

Q: Can these parts be used interchangeably in high-speed applications?

A: Both parts specify identical propagation delay of 5ns @ 5V with 50pF load. Timing performance is equivalent for applications within the 0°C ~ 70°C operating temperature range.
