8.2.2 Detailed Design Procedure
See Power Supply Recommendations, Layout, and Thermal Considerations for key design considerations
regarding the input supply, grounding, and thermal calculations specific to the SM74101.
8.2.3 Application Curve
The rise and fall times of the OUT signal will depend on the capacitance of the MOSFET gate. Therefore, an
appropriate MOSFET should be selected to meet the switching speed and efficiency requirements of the system.
