Substitute Part Grouping Explanation

Substitution of the DS3668N/HAPB is determined by strict equivalence across the following critical parameters:

• Driver Configuration: 4/0 driver/receiver count
• Supply Voltage Range: 3V ~ 5.25V compatibility
• Operating Temperature Range: -40°C ~ 125°C
• Package Type: 16-DIP (0.300", 7.62mm) form factor
• Base Product Series: DS3668 family

The DS3668N/NOPB meets all substitution criteria as an active product variant within the same base product family, maintaining identical electrical specifications and physical packaging while offering improved product status and compliance certifications.

Parameter Comparison
