DM74ALS11AMX Equivalent & Substitute Parts

Part Overview

The DM74ALS11AMX 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 package, operating at 4.5V to 5.5V supply voltage with a maximum propagation delay of 13ns at 5V with 50pF load. The part is currently listed as obsolete, making equivalent substitutes necessary for ongoing design support and procurement.

Substitute Part Grouping Explanation

Substitution for the DM74ALS11AMX is determined by strict equivalence across the following critical parameters:

Logic function: 3-channel AND gate with 3 inputs per channel
Electrical specifications: 4.5V–5.5V supply, 400µA/8mA output current, 0.8V/2V input logic levels, 13ns propagation delay at 5V with 50pF load
Operating temperature range: 0°C–70°C
Package type: 14-SOIC surface mount
Series classification: 74ALS logic family

Three substitute parts meet these criteria across different packaging and product status configurations. All substitutes maintain identical functional and electrical parameters, with variations only in manufacturer (Texas Instruments), packaging format (Tube, Tape & Reel), and product lifecycle status.

Engineering Selection Recommendations

SN74ALS11ADR (Texas Instruments) is the primary substitute for new designs and procurement. This part maintains identical electrical and mechanical specifications to the DM74ALS11AMX, including the 14-SOIC (0.154", 3.90mm) package footprint. The SN74ALS11ADR carries Active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment.

SN74ALS11AD (Texas Instruments) provides equivalent functionality with Last Time Buy status. This part is suitable for legacy system support where existing inventory must be replenished. Packaging is supplied in Tube format rather than Tape & Reel.

SN74ALS11ANSR (Texas Instruments) is functionally equivalent but uses a wider 14-SOIC package (0.209", 5.30mm width) compared to the standard 0.154" width. This part is appropriate only when PCB layout accommodates the larger package footprint. Active product status and ROHS3 compliance apply.

Selection should prioritize SN74ALS11ADR for new designs due to Active status and standard package dimensions. Alternative substitutes are valid only when specific packaging or inventory constraints apply.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS11ANSR replace DM74ALS11AMX directly on existing PCBs?

A: No. The SN74ALS11ANSR uses a 14-SOIC package with 0.209" width, while the DM74ALS11AMX and primary substitutes use 0.154" width. PCB footprints are not compatible. Use SN74ALS11ADR or SN74ALS11AD for direct board-level substitution.

Q: What is the difference between SN74ALS11AD and SN74ALS11ADR?

A: Both parts are electrically and functionally identical with matching 14-SOIC (0.154", 3.90mm) packages. The primary difference is packaging format: SN74ALS11AD is supplied in Tube, while SN74ALS11ADR is supplied in Tape & Reel (TR). SN74ALS11ADR has Active product status; SN74ALS11AD is Last Time Buy.

Q: Are all substitutes RoHS compliant?

A: Yes. All three Texas Instruments substitutes (SN74ALS11AD, SN74ALS11ANSR, SN74ALS11ADR) are ROHS3 compliant. The original onsemi DM74ALS11AMX RoHS status is not specified in available documentation.

Q: What is the operating temperature range for these parts?

A: All parts, including the DM74ALS11AMX and all substitutes, operate across 0°C to 70°C. This range is consistent across the entire 74ALS logic family.

Q: Can I use these parts interchangeably in high-speed applications?

A: Yes, within the specified operating conditions. All parts maintain identical maximum propagation delay of 13ns at 5V with 50pF load. Substitution does not affect timing performance.
