Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74LS153N is determined by strict equivalence across the following critical parameters:

• Circuit configuration: 2 x 4:1 multiplexer topology
• Package type: 16-DIP (0.300", 7.62mm) through-hole mounting
• Voltage supply range: 4.75V ~ 5.25V single supply
• Output current specifications: 400µA (high), 8mA (low)
• Operating temperature range: 0°C ~ 70°C
• Series classification: 74LS logic family

The SN74LS153N qualifies as a direct substitute based on identical electrical characteristics, circuit configuration, and physical packaging. Both components share the same base product number (74LS153) and are manufactured by onsemi.

Parameter Comparison

Engineering Selection Recommendations

Both the DM74LS153N and SN74LS153N are obsolete components with identical electrical and mechanical specifications. Selection between these parts should be based on availability and procurement lead times. Neither component meets current RoHS compliance requirements; applications requiring RoHS-compliant alternatives must evaluate modern multiplexer solutions outside the 74LS logic family.

For new designs, consider modern logic multiplexer families that provide equivalent functionality with current manufacturing status and compliance certifications. For legacy system maintenance and repair, either part number provides functional equivalence within the specified electrical and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can the SN74LS153N replace the DM74LS153N in existing designs?

A: Yes. Both components share identical circuit configuration (2 x 4:1 multiplexer), electrical specifications (voltage supply, output current, operating temperature), and physical packaging (16-DIP through-hole). Direct substitution is electrically and mechanically compatible.

Q: What determines if a part is a valid substitute for the DM74LS153N?

A: Valid substitutes must match all critical parameters: 2 x 4:1 circuit topology, 16-DIP package, 4.75V ~ 5.25V supply voltage, 400µA/8mA output current ratings, and 0°C ~ 70°C operating temperature range. Deviations in any parameter disqualify substitution.

Q: Are there modern alternatives to the DM74LS153N?

A: The DM74LS153N and SN74LS153N are both obsolete. Modern multiplexer solutions exist in current logic families, but these represent different product lines with different part numbers and specifications. Direct functional equivalents within the 74LS family are limited to the SN74LS153N variant.

Q: What is the difference between DM74LS153N and SN74LS153N?

A: Both parts are manufactured by onsemi with identical electrical and mechanical specifications. The difference is in the manufacturer's prefix designation (DM vs. SN). Functionally and electrically, they are equivalent.

Q: Can I use this component in new designs?

A: Both the DM74LS153N and SN74LS153N are obsolete and RoHS non-compliant. New designs should evaluate current-generation multiplexer components that meet modern compliance requirements and have active manufacturing status.
