Substitute Part Grouping Explanation

Substitution eligibility for the DM74LS04M is determined by the following criteria:

Logic type and circuit configuration (6-channel inverter, 1 input per channel)
Electrical specifications (supply voltage 4.75V ~ 5.25V, output current ratings, input logic levels, propagation delay)
Operating temperature range (0°C ~ 70°C)
Package compatibility (14-SOIC surface mount)
Base product number alignment (74LS04 family)

All substitute parts listed maintain these core parameters within the specified tolerances, ensuring functional and electrical equivalence for circuit-level replacement.

Engineering Selection Recommendations

For replacement of the obsolete DM74LS04M, the following selection criteria apply:

SN74LS04DR is the primary recommended substitute. This part maintains active product status with Texas Instruments, carries ROHS3 compliance certification, and is available in high inventory (20,100 pcs). The electrical and package specifications are fully equivalent to the DM74LS04M, with identical propagation delay characteristics at the specified load capacitance of 15pF.

SN74LS04NSR serves as an alternative substitute with active product status and ROHS3 compliance. This part differs in package width (0.209" vs. 0.154"), which may require PCB layout verification for footprint compatibility. Inventory availability is adequate at 3,400 pcs.

SN74LS04DG4 is available but carries a discontinued status at DiGi Electronics, limiting long-term procurement viability despite ROHS3 compliance and adequate current inventory.

SN74LS04D lacks complete specification documentation in the provided data, making it unsuitable as a primary selection without additional technical verification.
