DM74ALS32N Equivalent & Substitute Parts

Part Overview

The DM74ALS32N is a 4-channel OR gate logic IC manufactured by onsemi in a 14-MDIP package. This part is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The DM74ALS32N operates within the 74ALS logic family and provides standard OR gate functionality with 2 inputs per channel across 4 independent circuits. Substitute parts maintain identical functional and electrical characteristics while offering improved availability and active product status.

Substitute Part Grouping Explanation

Substitute parts for the DM74ALS32N are qualified based on strict electrical and mechanical parameter matching within the 74ALS logic family. The substitution criteria are:

Electrical Parameters (Must Match):

• Logic Type: OR Gate
• Number of Circuits: 4
• Number of Inputs: 2 per channel
• 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: 14ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C

Mechanical Parameters (Must Match):

• Mounting Type: Through Hole
• Package / Case: 14-DIP (0.300", 7.62mm)
• Series: 74ALS

All identified substitute parts meet these criteria and are functionally interchangeable with the DM74ALS32N at the circuit level.

Parameter Comparison

Engineering Selection Recommendations

Both SN74ALS32N and SN74ALS32NE4 from Texas Instruments are direct functional equivalents to the obsolete DM74ALS32N. Selection between these two Texas Instruments alternatives should be based on the following factors:

SN74ALS32N: This part carries active product status and ROHS3 compliance certification. It is suitable for applications requiring current manufacturing support and environmental compliance documentation.

SN74ALS32NE4: This part also maintains active product status and ROHS3 compliance. Both Texas Instruments variants are electrically and mechanically identical to the DM74ALS32N and provide equivalent circuit performance.

The choice between SN74ALS32N and SN74ALS32NE4 may be determined by packaging availability (Tube) and inventory levels at the time of procurement. Both parts are REACH Unaffected and classified under ECCN EAR99.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS32N and SN74ALS32NE4 be used interchangeably with DM74ALS32N?

A: Yes. Both Texas Instruments parts are direct substitutes. They match all critical electrical parameters (supply voltage, logic levels, propagation delay, output current) and mechanical specifications (14-DIP package, through-hole mounting, 74ALS series).

Q: What is the difference between SN74ALS32N and SN74ALS32NE4?

A: Both parts are electrically and mechanically identical. The primary difference is product designation. Both are active products with ROHS3 compliance and equivalent availability.

Q: Why is the DM74ALS32N listed as obsolete?

A: The DM74ALS32N has been discontinued by onsemi. Texas Instruments continues to manufacture functionally equivalent 74ALS32 variants, making substitution straightforward for ongoing designs and repairs.

Q: Are there any package differences between these parts?

A: No. All three parts use the 14-DIP (0.300", 7.62mm) through-hole package. Pin configuration and mechanical dimensions are identical, allowing direct socket replacement.

Q: Do the substitute parts meet environmental compliance requirements?

A: The Texas Instruments substitutes (SN74ALS32N and SN74ALS32NE4) are ROHS3 compliant and REACH Unaffected. The original DM74ALS32N has REACH Unaffected status; RoHS compliance was not specified for this part.

Q: What is the operating temperature range?

A: All three parts operate across 0°C to 70°C, maintaining identical thermal specifications for circuit design purposes.
