Substitute Part Grouping Explanation

Substitution of the DM74ALS804AN is determined by strict equivalence across the following critical parameters:

• Logic Type: NAND Gate configuration
• Number of Circuits: 6 channels
• Number of Inputs: 2 inputs per gate
• Voltage - Supply: 4.5V ~ 5.5V operating range
• Current - Output High, Low: 15mA, 24mA output drive capability
• Input Logic Level - Low: 0.8V threshold
• Input Logic Level - High: 2V threshold
• Max Propagation Delay @ V, Max CL: 8ns @ 5V, 50pF
• Operating Temperature: 0°C ~ 70°C range
• Package / Case: 20-DIP (0.300", 7.62mm)
• Mounting Type: Through Hole
• Series: 74ALS

All substitute parts must match these parameters exactly to ensure functional and electrical compatibility in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The SN74ALS804AN manufactured by Texas Instruments is a direct parametric equivalent to the DM74ALS804AN. Both parts share identical electrical specifications, logic configuration, and physical packaging. The primary distinction is product status: the DM74ALS804AN is obsolete, while the SN74ALS804AN maintains active production status.

For new designs and production applications, the SN74ALS804AN is the appropriate selection due to its active availability and ROHS3 compliance certification. Both parts maintain REACH Unaffected status and are classified under identical ECCN and HTSUS codes, confirming regulatory equivalence.
