Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74LS10N is determined by strict adherence to the following parameters:

• Logic Family: Must belong to the 74LS series to ensure electrical compatibility
• Logic Function: Must be a NAND Gate with identical circuit count (3 channels) and input configuration (3 inputs per channel)
• Electrical Specifications: Supply voltage, output current ratings, input logic levels, and propagation delay must match or exceed the original specifications
• Package Type: Must use 14-DIP through-hole packaging with identical pin configuration
• Operating Temperature Range: Must support the 0°C ~ 70°C operating window

The SN74LS10N from Motorola meets these criteria as a direct substitute within the 74LS logic family.

Parameter Comparison

Engineering Selection Recommendations

The SN74LS10N is a direct functional equivalent to the DM74LS10N. Both components are classified within the 74LS logic family and share identical pin configurations, logic function, and electrical operating parameters. The SN74LS10N maintains active product status, whereas the DM74LS10N is obsolete. Both components are REACH Unaffected, indicating compliance with regulatory requirements.

Selection between these parts should be based on availability, supply chain considerations, and cost factors. The SN74LS10N is recommended for new designs and ongoing production due to its active status and established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS10N replace the DM74LS10N in existing designs?

A: Yes. Both components are 74LS series NAND gates with identical logic function (3 channels, 3 inputs per channel), electrical specifications, and 14-DIP package configuration. Direct pin-for-pin substitution is possible without circuit modification.

Q: Are there differences in electrical performance between these parts?

A: No. Both components operate within the same supply voltage range (4.75V ~ 5.25V), share identical input logic levels, output current ratings, and propagation delay specifications. Electrical performance is equivalent.

Q: What is the significance of the DM74LS10N being obsolete?

A: Obsolete status indicates the DM74LS10N is no longer manufactured by onsemi. The SN74LS10N, with active product status, ensures continued availability for replacement and new applications.

Q: Are there package or mounting differences?

A: No. Both components use 14-DIP through-hole packaging with identical physical dimensions (0.300", 7.62mm). No PCB layout modifications are required for substitution.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the DM74LS10N and SN74LS10N are REACH Unaffected, indicating equivalent regulatory compliance status.
