DM74ALS09N Equivalent & Substitute Parts

Part Overview

The DM74ALS09N is a 4-channel AND gate logic IC with open collector outputs, manufactured by onsemi in a 14-MDIP package. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing system support and new designs. The DM74ALS09N operates within the 74ALS logic family standard, which defines compatible alternatives based on matching electrical characteristics and package specifications.

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS09N are identified based on strict parametric equivalence within the 74ALS logic family. The following criteria determine substitutability:

• Logic type and circuit configuration (4-channel AND gate with 2 inputs per channel)
• Open collector output feature
• Electrical specifications (supply voltage, input/output levels, propagation delay)
• Package type and pin compatibility (14-DIP form factor)
• Operating temperature range
• Mounting technology (through hole)

The SN74ALS09N from Texas Instruments meets all these criteria and is classified as a parametric equivalent. Substitution is valid when the receiving circuit design accommodates the specified electrical and mechanical parameters without modification.

Engineering Selection Recommendations

The SN74ALS09N is a direct parametric substitute for the DM74ALS09N. Selection between these parts should be based on the following factors:

• Product status: The SN74ALS09N carries Active status, ensuring continued availability and manufacturing support, whereas the DM74ALS09N is Obsolete.
• Compliance: The SN74ALS09N is RoHS3 compliant, providing environmental regulatory alignment for new designs.
• Inventory availability: The SN74ALS09N is available in higher stock quantities (5755 Pcs) compared to the DM74ALS09N (2430 Pcs).
• Packaging: The SN74ALS09N is supplied in Tube packaging, whereas the DM74ALS09N packaging specification is not defined.

For applications currently using the DM74ALS09N, the SN74ALS09N provides full electrical and mechanical compatibility without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS09N directly replace the DM74ALS09N in existing designs?

A: Yes. Both parts are 74ALS series AND gates with identical logic configurations, electrical specifications, and 14-DIP package dimensions. Direct pin-for-pin substitution is valid.

Q: Are there differences in output drive capability between these parts?

A: No. Both parts specify identical output current ratings (8mA low) and propagation delay characteristics (54ns @ 5V, 50pF).

Q: What is the significance of the DM74ALS09N being obsolete?

A: Obsolete status indicates the part is no longer manufactured by onsemi. The SN74ALS09N, with Active status, is the recommended alternative for new designs and ongoing production support.

Q: Do package differences affect substitution?

A: Both parts use the 14-DIP (0.300", 7.62mm) form factor with through-hole mounting. Package compatibility is confirmed. Packaging format (Tube vs. unspecified) does not affect electrical or mechanical fit.

Q: Are there compliance or regulatory differences?

A: The SN74ALS09N is RoHS3 compliant. Both parts are REACH unaffected and carry EAR99 ECCN classification. For applications requiring RoHS compliance, the SN74ALS09N is the appropriate selection.
