DM74ALS10AM NAND Gate IC Equivalent & Substitute Parts

Part Overview

The DM74ALS10AM is a 3-channel NAND gate IC manufactured by onsemi in a 14-SOIC surface mount package. This component implements three independent 3-input NAND logic functions and operates within the standard 4.5V to 5.5V supply voltage range. The part is currently classified as obsolete, making identification of equivalent and substitute components essential for ongoing design support and production continuity.

Substitute Part Grouping Explanation

Substitution of the DM74ALS10AM is determined by strict equivalence across the following critical parameters:

Logic function: 3-channel NAND gate with 3 inputs per channel
Electrical specifications: 4.5V ~ 5.5V supply voltage, 400µA output high current, 8mA output low current, 0.8V input low threshold, 2V input high threshold, 11ns maximum propagation delay at 5V with 50pF load
Operating temperature range: 0°C ~ 70°C
Mounting type: Surface mount
Series classification: 74ALS

Three substitute parts meet these criteria. SN74ALS10ADR and SN74ALS10AD are direct functional equivalents manufactured by Texas Instruments with identical electrical and logical specifications. SN74ALS10ANSR is a parametric equivalent with the same logic function and electrical performance but differs in package dimensions (0.209" versus 0.154" width).

Engineering Selection Recommendations

SN74ALS10ADR is the primary substitute for the DM74ALS10AM. This Texas Instruments part maintains identical package dimensions (14-SOIC, 0.154" width), electrical specifications, and logic configuration. The part is currently in active production status with ROHS3 compliance certification, ensuring long-term availability and regulatory alignment.

SN74ALS10AD provides an alternative with identical electrical and package specifications but is classified as Last Time Buy, indicating limited future availability. This part is suitable for applications where existing inventory can support production timelines.

SN74ALS10ANSR is a parametric equivalent with identical electrical performance but features a wider package body (0.209" versus 0.154" width). This part is suitable only for applications where PCB layout accommodates the increased package width. The part is in active production status with ROHS3 compliance.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS10ANSR be used as a direct replacement for DM74ALS10AM on existing PCBs?

A: SN74ALS10ANSR has identical electrical specifications and logic function but differs in package width (0.209" versus 0.154"). Direct PCB substitution is not possible without layout modification. The wider package body may conflict with existing component placement or trace routing.

Q: What is the difference between SN74ALS10ADR and SN74ALS10AD?

A: Both parts are manufactured by Texas Instruments with identical electrical specifications, logic function, and package dimensions. The primary difference is packaging format: SN74ALS10ADR is supplied in Tape & Reel format, while SN74ALS10AD is supplied in Tube format. SN74ALS10AD is classified as Last Time Buy, indicating reduced future availability compared to the active SN74ALS10ADR.

Q: Are all substitute parts RoHS compliant?

A: SN74ALS10ADR, SN74ALS10ANSR, and SN74ALS10AD are all ROHS3 compliant. The original DM74ALS10AM RoHS status is not specified in available documentation.

Q: What is the moisture sensitivity level for these parts?

A: All parts, including the original DM74ALS10AM and all substitutes, have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

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

A: SN74ALS10ADR and SN74ALS10AD are fully interchangeable in new designs with identical package footprints and electrical performance. SN74ALS10ANSR requires PCB layout verification due to package width differences. All three parts maintain the same logic function, supply voltage range, propagation delay, and operating temperature specifications.
