Substitute Part Grouping Explanation

Substitute parts for the DM74ALS86M are classified based on strict electrical and mechanical parameter matching within the 74ALS logic family. All substitute candidates maintain identical functional specifications: 4-channel XOR gate configuration, 2 inputs per channel, 4.5V to 5.5V supply voltage operation, 17ns maximum propagation delay at 5V with 50pF load, and 0°C to 70°C operating temperature range.

Substitution eligibility is determined by the following key parameters:

• Logic Type: XOR (Exclusive OR)
• Number of Circuits: 4
• Number of Inputs: 2
• 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: 17ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C
• Mounting Type: Surface Mount
• Base Product Number: 74ALS86

Packaging variations (14-SOIC with different width specifications and 14-SO) are permitted substitutes when mechanical constraints of the application allow. Manufacturer differences between onsemi and Texas Instruments do not affect functional compatibility within the 74ALS standard.

Engineering Selection Recommendations

For applications currently using the DM74ALS86M, the following selection criteria apply based on product status and compliance:

Primary Selection: SN74ALS86DR (Texas Instruments) This part is classified as Active with ROHS3 compliance. It maintains identical electrical parameters and 14-SOIC packaging (0.154", 3.90mm width) matching the original DM74ALS86M. This part is suitable for new designs and ongoing production requiring long-term availability.

Secondary Selection: SN74ALS86D (Texas Instruments) This part is classified as Last Time Buy with ROHS3 compliance. It provides identical electrical parameters and 14-SOIC packaging (0.154", 3.90mm width). This option is appropriate for applications with established supply chain relationships but should be evaluated for long-term sourcing strategy.

Alternative Selection: SN74ALS86NSR (Texas Instruments) This part is classified as Active with ROHS3 compliance. It maintains identical electrical parameters but uses 14-SO packaging with 0.209" (5.30mm) width. This option is suitable only when mechanical board layout constraints permit the wider package footprint.

Frequently Asked Questions (FAQ)

Q: Can SN74ALS86DR directly replace DM74ALS86M without circuit modification? A: Yes. The SN74ALS86DR maintains all electrical parameters, supply voltage range, input/output logic levels, propagation delay, and operating temperature specifications. The 14-SOIC package dimensions are identical (0.154", 3.90mm width), allowing direct PCB footprint compatibility.

Q: What is the difference between SN74ALS86DR and SN74ALS86D? A: Both parts are electrically identical and use the same 14-SOIC package (0.154", 3.90mm width). The primary difference is product status: SN74ALS86DR is Active, while SN74ALS86D is Last Time Buy. For new designs, SN74ALS86DR is recommended due to extended availability.

Q: Can SN74ALS86NSR be used as a substitute? A: SN74ALS86NSR is electrically equivalent but uses a wider 14-SO package (0.209", 5.30mm width) compared to the original 14-SOIC (0.154", 3.90mm width). Substitution is possible only if the PCB layout accommodates the wider package footprint without requiring board redesign.

Q: Are all substitute parts ROHS3 compliant? A: Yes. SN74ALS86DR, SN74ALS86D, and SN74ALS86NSR are all ROHS3 compliant. The original DM74ALS86M RoHS status is not specified in the provided data.

Q: What is the significance of the 74ALS base product number? A: The 74ALS designation indicates the logic family standard. All parts listed (DM74ALS86M, SN74ALS86DR, SN74ALS86D, SN74ALS86NSR) belong to the 74ALS family, ensuring functional and electrical compatibility within TTL-compatible digital logic applications.

Q: Are there packaging differences that affect soldering or assembly? A: SN74ALS86DR and SN74ALS86D use identical 14-SOIC packaging (0.154", 3.90mm width) with no assembly differences from DM74ALS86M. SN74ALS86NSR uses 14-SO packaging with 0.209" (5.30mm) width, requiring verification of PCB pad spacing and assembly equipment compatibility before substitution.
