Procurement Notes

Verify the specific suffix 'SN' corresponds to the 8-pin SOIC package variant. Confirm AEC-Q100 qualification status if automotive compliance is required. Check humidity sensitivity level (HSL) handling requirements during storage and assembly. Ensure input voltage levels match the specified CMOS/TTL compatibility range.

Selection Notes

Select this component when dual low-side driving is required for synchronous rectification or half-bridge configurations. Consider the 4.5 V minimum operating voltage and 18 V maximum supply limit. Evaluate thermal performance based on PCB layout and duty cycle. Verify that the 28 ns switching speed meets the target frequency requirements.
