DM74ALS10ASJX Equivalent & Substitute Parts

Part Overview

The DM74ALS10ASJX is a NAND Gate IC with 3 channels and 3 inputs per channel in a 14-SOP package, manufactured by onsemi. This logic component operates within the 74ALS series standard and is classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for design continuity and procurement planning. Substitute parts maintain identical electrical characteristics and functional performance while offering improved availability and product status.

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS10ASJX are qualified based on strict electrical and mechanical parameter matching:

Electrical Parameters (Must Match):

Logic Type: NAND Gate
Number of Circuits: 3
Number of Inputs: 3
Voltage - Supply: 4.5V ~ 5.5V
Current - Output High, Low: 400µA, 8mA
Input Logic Level - Low: 0.8V
Input Logic Level - High: 2V
Max Propagation Delay @ V, Max CL: 11ns @ 5V, 50pF
Operating Temperature: 0°C ~ 70°C
Base Product Number: 74ALS10

Mechanical Parameters (Package Compatibility):

Mounting Type: Surface Mount
Moisture Sensitivity Level (MSL): 1 (Unlimited)

All identified substitute parts maintain these parameters. Package variations (14-SOP, 14-SOIC, 14-SO) are functionally equivalent for the 74ALS10 logic function and differ only in physical dimensions and supplier device packaging designations.

Engineering Selection Recommendations

SN74ALS10ADR (Texas Instruments) is the primary substitute for new designs and procurement. This part is in active product status with ROHS3 compliance, ensuring long-term availability and regulatory alignment. It is supplied in Tape & Reel packaging with 3700 units in stock.

SN74ALS10ANSR (Texas Instruments) serves as an alternative substitute with active product status and ROHS3 compliance. This part offers the highest inventory availability at 5300 units and is suitable for high-volume applications.

SN74ALS10AD (Texas Instruments) is classified as Last Time Buy and should be considered only when specific packaging requirements (Tube) are mandated. This part maintains full electrical equivalence but has limited procurement window.

All three Texas Instruments substitutes provide superior product status compared to the obsolete DM74ALS10ASJX and meet current regulatory compliance requirements.
