Substitute Part Grouping Explanation

Substitution of the DM74AS804BWM is based on strict equivalence across the following critical parameters:

• Logic Type: NAND Gate (6 channels, 2 inputs per channel)
• Electrical Specifications: Voltage supply range, output current ratings, input logic levels, and propagation delay
• Package Type: 20-SOIC surface mount package with identical physical dimensions
• Operating Temperature Range: 0°C ~ 70°C
• Moisture Sensitivity Level: MSL 1 (Unlimited)

The SN74AS804BDW from Texas Instruments meets all these criteria and is classified as an active product, providing a direct functional and electrical equivalent for the obsolete DM74AS804BWM.
