Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74AS10N is determined by strict equivalence across the following critical parameters:

• Logic Function: NAND Gate with identical 3-channel, 3-input configuration
• Electrical Specifications: Matching supply voltage range (4.5V ~ 5.5V), output current ratings (2mA high, 20mA low), input logic thresholds (0.8V low, 2V high), and propagation delay (4.5ns @ 5V, 50pF)
• Thermal Operating Range: 0°C ~ 70°C
• Physical Package: 14-DIP form factor with 0.300" (7.62mm) pitch, compatible with through-hole mounting
• Series Standard: 74AS logic family

The SN74AS10N from Texas Instruments meets all these criteria as a parametrically equivalent substitute, sharing the identical base product number (74AS10) and electrical performance specifications.

Engineering Selection Recommendations

The SN74AS10N from Texas Instruments is the direct parametric equivalent for the obsolete DM74AS10N. Selection of the SN74AS10N is supported by:

• Product Status: The SN74AS10N maintains Active status, ensuring ongoing availability and manufacturing support, whereas the DM74AS10N is obsolete.
• Regulatory Compliance: Both parts share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining compliance consistency.
• Electrical Equivalence: Complete parameter matching across all specified electrical and thermal characteristics ensures functional interchangeability in existing circuit designs.
• Physical Compatibility: Identical 14-DIP package geometry and through-hole mounting type enable direct board-level substitution without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the SN74AS10N directly replace the DM74AS10N in existing designs?

A: Yes. The SN74AS10N is a parametrically equivalent substitute with identical electrical specifications, operating temperature range, and 14-DIP package configuration. Direct substitution is supported without circuit modification.

Q: What are the key differences between these parts?

A: The primary differences are manufacturer (onsemi vs. Texas Instruments) and product status (obsolete vs. active). All electrical and mechanical parameters are identical.

Q: Are there any compliance or regulatory differences?

A: No. Both parts share identical REACH status (REACH Unaffected) and ECCN classification (EAR99), maintaining regulatory equivalence.

Q: Does the packaging differ between these parts?

A: Both parts use the 14-DIP (0.300", 7.62mm) package with through-hole mounting. Physical compatibility is maintained.

Q: Why is the DM74AS10N listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The SN74AS10N from Texas Instruments provides continued access to this logic function with active manufacturing support.
