Substitute Part Grouping Explanation

Substitution of the SN74LS02NSRG4 is determined by strict equivalence across the following critical parameters:

• Logic Type: NOR Gate (4 channels, 2 inputs per channel)
• Voltage - Supply: 4.75V ~ 5.25V
• Current - Output High, Low: 400µA, 16mA
• Input Logic Level - Low: 0.8V
• Input Logic Level - High: 2V
• Max Propagation Delay @ V, Max CL: 15ns @ 5V, 15pF
• Operating Temperature: 0°C ~ 70°C (TA)
• Package / Case: 14-SOIC (0.209", 5.30mm Width)
• Mounting Type: Surface Mount

The SN74LS02NSR meets all these parameters and qualifies as a parametric equivalent. Both parts share identical electrical specifications, logic configuration, and physical packaging, enabling direct substitution in circuit designs.
