Substitute Part Grouping Explanation

Substitution of the DM74S04N is determined by strict equivalence across the following critical parameters:

• Logic Type: Inverter (6-channel, single input per channel)
• Electrical Specifications: Voltage supply range 4.75V ~ 5.25V, output current ratings 1mA/20mA, input logic thresholds 0.8V/2V
• Propagation Delay: Maximum 8ns at 5V with 50pF load
• Package Form Factor: 14-DIP through-hole mounting with 0.300" (7.62mm) pitch
• Base Product Series: 74S logic family

The SN74S04N from Texas Instruments meets all substitution criteria. Both parts share identical logic functionality, electrical performance windows, and physical package dimensions, enabling direct replacement in existing circuit designs.
