Substitute Part Grouping Explanation

Substitution of the DM74ALS37AN is determined by strict adherence to the 74ALS logic family standard. The following parameters must match identically for functional equivalence:

• Logic Type: NAND Gate (4 channels, 2 inputs per channel)
• Voltage Supply Range: 4.5V ~ 5.5V
• Output Current Specifications: 2.6mA (high), 24mA (low)
• Input Logic Levels: 0.8V (low), 2V (high)
• Propagation Delay: 8ns @ 5V, 50pF
• Operating Temperature Range: 0°C ~ 70°C
• Package Configuration: 14-DIP (0.300", 7.62mm)
• Base Product Number: 74ALS37

The SN74ALS37AN from Texas Instruments meets all these criteria and is classified as a parametric equivalent. Both parts share identical electrical performance specifications and physical package dimensions, enabling direct substitution in circuit applications.
