Substitute Part Grouping Explanation

Substitution of the DM74ALS86N is determined by strict adherence to the 74ALS logic family standard. All substitute parts must match the following critical parameters:

• Logic Type: XOR (Exclusive OR)
• Number of Circuits: 4
• Number of Inputs: 2
• Voltage Supply Range: 4.5V ~ 5.5V
• Output Current Specifications: 400µA (high), 8mA (low)
• Input Logic Levels: 0.8V (low), 2V (high)
• Propagation Delay: 17ns @ 5V, 50pF
• Operating Temperature Range: 0°C ~ 70°C
• Package Type: 14-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole

The SN74ALS86N from Texas Instruments meets all these parameters and qualifies as a direct equivalent substitute.

Engineering Selection Recommendations

The SN74ALS86N from Texas Instruments is the qualified substitute for the obsolete DM74ALS86N. Both components share identical electrical specifications and mechanical packaging, ensuring pin-for-pin compatibility and functional equivalence in 74ALS XOR logic applications.

The SN74ALS86N offers the advantage of active product status with current manufacturing support. The Texas Instruments variant carries ROHS3 compliance certification, providing additional environmental and regulatory assurance for new designs and long-term procurement strategies.

Both parts maintain REACH Unaffected status and EAR99 export classification. The electrical performance, including propagation delay, output current drive, and input logic thresholds, is identical across both manufacturers, confirming direct substitution capability without circuit redesign.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS86N replace the DM74ALS86N in existing designs?

A: Yes. The SN74ALS86N is a direct pin-for-pin and functional equivalent. All electrical parameters, timing specifications, and package dimensions are identical. No circuit modifications are required.

Q: Are there any differences in package specifications between these parts?

A: Both parts use the 14-DIP (0.300", 7.62mm) package with through-hole mounting. Package dimensions and pin assignments are identical.

Q: What is the significance of the product status difference?

A: The DM74ALS86N is obsolete, meaning onsemi no longer manufactures or supports this part. The SN74ALS86N is active, ensuring continued availability, technical support, and compliance with current manufacturing standards.

Q: Do these parts have different compliance certifications?

A: Both parts maintain REACH Unaffected status and EAR99 export classification. The SN74ALS86N additionally carries ROHS3 compliance, which is beneficial for applications requiring environmental compliance documentation.

Q: Are the electrical specifications identical?

A: Yes. Supply voltage range (4.5V ~ 5.5V), output current (400µA high, 8mA low), input logic levels (0.8V low, 2V high), propagation delay (17ns @ 5V, 50pF), and operating temperature range (0°C ~ 70°C) are identical across both manufacturers.
