DM74ALS11AM Equivalent & Substitute Parts

Part Overview

The DM74ALS11AM is a 3-channel AND gate logic IC manufactured by onsemi in 14-SOIC surface mount packaging. This component implements three independent 3-input AND gates in a single 14-pin package, operating within the 4.5V to 5.5V supply voltage range. The part is currently classified as obsolete, making equivalent substitutes necessary for ongoing design support and procurement. Substitute parts maintain identical logic functionality and electrical performance while offering improved availability and product status options.

Substitute Part Grouping Explanation

Substitution of the DM74ALS11AM is determined by strict equivalence across the following parameters: logic type (AND gate), number of circuits (3), number of inputs (3), supply voltage range (4.5V ~ 5.5V), output current specifications (400µA, 8mA), input logic levels (0.8V low, 2V high), propagation delay (13ns @ 5V, 50pF), operating temperature range (0°C ~ 70°C), and mounting type (surface mount). Package variations within the 14-SOIC family are permitted when mechanical dimensions remain compatible with the specified footprint tolerance.

The substitute parts are categorized as follows:

Direct Manufacturer Equivalent: SN74ALS11ADR maintains identical electrical and mechanical specifications with tape & reel packaging and active product status.

Similar Manufacturer Equivalent: SN74ALS11ANSR provides equivalent electrical performance with a package width variation (0.209" vs. 0.154") and active product status.

Parametric Equivalent: SN74ALS11AD matches all electrical parameters with tube packaging and last-time-buy product status.

Engineering Selection Recommendations

SN74ALS11ADR is the primary substitute for new designs and procurement. This Texas Instruments part maintains active product status, ROHS3 compliance, and identical electrical and mechanical specifications to the DM74ALS11AM. Tape & reel packaging supports automated assembly processes.

SN74ALS11ANSR provides an alternative with equivalent electrical performance and active status. The package width variation (0.209" vs. 0.154") requires PCB layout verification to confirm mechanical compatibility with existing footprints. ROHS3 compliance is maintained.

SN74ALS11AD is suitable for applications where last-time-buy inventory is acceptable. This part matches all electrical parameters and maintains identical package dimensions to the original DM74ALS11AM. Tube packaging is appropriate for lower-volume applications. ROHS3 compliance is provided.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS11ANSR be used as a direct replacement for DM74ALS11AM?

A: SN74ALS11ANSR is electrically equivalent but has a different package width (0.209" vs. 0.154"). PCB layout compatibility must be confirmed before substitution. If the PCB footprint accommodates the wider package, electrical substitution is valid.

Q: What is the difference between the three substitute parts?

A: All three substitutes provide identical electrical performance. The differences are: SN74ALS11ADR (active status, tape & reel packaging), SN74ALS11ANSR (active status, wider package), and SN74ALS11AD (last-time-buy status, tube packaging). Selection depends on product lifecycle requirements and packaging needs.

Q: Are all substitutes ROHS3 compliant?

A: Yes. SN74ALS11ADR, SN74ALS11ANSR, and SN74ALS11AD are all ROHS3 compliant. The original DM74ALS11AM is REACH unaffected.

Q: Can these parts be used interchangeably in existing designs?

A: Electrical interchangeability is confirmed across all parameters. Mechanical interchangeability depends on package dimensions. SN74ALS11ADR and SN74ALS11AD have identical footprints to DM74ALS11AM. SN74ALS11ANSR requires PCB layout verification due to package width variation.

Q: Which substitute should be selected for new production?

A: SN74ALS11ADR is recommended for new production due to active product status and standard tape & reel packaging for automated assembly.
