Substitute Part Grouping Explanation

Substitute parts for the DM74ALS153N are qualified based on the following electrical and mechanical parameters:

• Circuit Configuration: 2 x 4:1 multiplexer topology
• Package Type: 16-DIP (0.300", 7.62mm) through-hole mounting
• Voltage Supply Range: 4.5V ~ 5.5V single supply
• Output Current Specifications: 2.6mA (high), 24mA (low)
• Operating Temperature Range: 0°C ~ 70°C
• Independent Circuits: 1

All substitute parts maintain identical electrical performance and mechanical compatibility with the original DM74ALS153N. Substitutes are available from Texas Instruments in active product status, providing long-term availability and supply chain continuity.

Parameter Comparison

Engineering Selection Recommendations

SN74ALS153N (Texas Instruments) is the direct manufacturer equivalent. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment.

SN74ALS253N (Texas Instruments) is a parametric equivalent with identical performance characteristics. The base product number differs (74ALS253 vs. 74ALS153), but all critical electrical parameters and package specifications remain equivalent for substitution purposes.

SN74AS153N (Texas Instruments) is a parametric equivalent from the 74AS logic family. This part shares the same circuit configuration, package, and electrical performance specifications. The 74AS series represents an alternative logic family within the same functional class.

All three substitute parts are manufactured by Texas Instruments with active product status, ROHS3 compliance, and REACH unaffected designation, providing regulatory compliance and supply chain stability superior to the obsolete DM74ALS153N.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS153N directly replace DM74ALS153N in existing designs?

A: Yes. The SN74ALS153N is a direct manufacturer equivalent with identical electrical specifications, output current ratings, voltage supply range, operating temperature, and 16-DIP package configuration. No design modifications are required.

Q: What is the difference between SN74ALS153N and SN74ALS253N?

A: Both parts are parametric equivalents with identical electrical performance and package specifications. The base product numbers differ (74ALS153 vs. 74ALS253), but all critical parameters determining substitution compatibility are equivalent. Selection between these parts depends on availability and procurement preferences.

Q: How does SN74AS153N differ from the ALS variants?

A: SN74AS153N belongs to the 74AS logic family rather than 74ALS. Both families maintain the same 2 x 4:1 multiplexer circuit configuration, package type, voltage supply range, and output current specifications. The AS family represents an alternative logic technology within the same functional class.

Q: Are all substitute parts available in the same packaging?

A: Yes. All substitute parts are supplied in 16-DIP (0.300", 7.62mm) through-hole packages, maintaining mechanical compatibility with the original DM74ALS153N for direct board-level substitution.

Q: What compliance certifications apply to the substitute parts?

A: All Texas Instruments substitute parts (SN74ALS153N, SN74ALS253N, SN74AS153N) are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement and deployment.
