Key Parameters

Substitute Part Grouping Explanation

Substitution of the DM74ALS1008AM is determined by strict equivalence across the following parameters:

• Logic family and type: 74ALS AND gate configuration
• Circuit and input count: 4 channels with 2 inputs per channel
• Supply voltage range: 4.5V ~ 5.5V compatibility
• Input logic thresholds: Low 0.8V, High 2V
• Operating temperature range: 0°C ~ 70°C
• Package type and dimensions: 14-SOIC surface mount form factor
• Moisture sensitivity classification: MSL 1

The SN74ALS08DR from Texas Instruments meets all these substitution criteria, maintaining functional and electrical equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS08DR is the direct equivalent substitute for the DM74ALS1008AM. Both components share identical logic family classification, circuit configuration, and package specifications. The SN74ALS08DR offers the advantage of active product status, ensuring continued availability and supply chain reliability. The Texas Instruments part carries ROHS3 compliance certification, meeting current environmental and regulatory requirements for new designs and production applications.

The DM74ALS1008AM's obsolete status necessitates transition to the SN74ALS08DR for ongoing component procurement. Both parts maintain compatibility across all critical electrical parameters including supply voltage, input logic thresholds, and operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can the SN74ALS08DR directly replace the DM74ALS1008AM in existing designs?

A: Yes. Both components are 14-SOIC surface mount packages with identical pinouts, logic family classification, and electrical specifications for supply voltage, input thresholds, and operating temperature. Direct substitution is supported without circuit modification.

Q: What are the differences in output current specifications?

A: The DM74ALS1008AM specifies 2.6mA output high and 24mA output low current. The SN74ALS08DR specifies 400µA output high and 8mA output low current. Both values remain within acceptable operating ranges for 74ALS logic family applications. Verify output current requirements for your specific application load conditions.

Q: Does the propagation delay difference affect circuit performance?

A: The DM74ALS1008AM specifies 9ns maximum propagation delay while the SN74ALS08DR specifies 14ns at identical test conditions (5V, 50pF load). The 5ns difference is within typical 74ALS logic family tolerances. Confirm timing requirements for critical path applications.

Q: Are there packaging or moisture sensitivity differences?

A: Both components use identical 14-SOIC surface mount packaging with 0.154" width and 3.90mm dimensions. Both carry MSL 1 (Unlimited) moisture sensitivity classification, requiring no special handling differences.

Q: What compliance certifications apply to the substitute part?

A: The SN74ALS08DR carries ROHS3 compliance certification. Both components are REACH Unaffected and classified under ECCN EAR99 for export purposes.
