Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance when sourcing. Confirm availability status as the component may be subject to limited supply or discontinuation. Ensure the PDIP-8 through-hole package matches the target PCB footprint requirements. Cross-reference the manufacturer datasheet for absolute maximum ratings to prevent operational damage during integration.

Selection Notes

Select this component when a dual high-side driver is required for N-channel MOSFETs in a half-bridge setup. Consider the 22 V input limit and PDIP-8 package constraints. Evaluate micropower requirements against alternative drivers if lower quiescent current is critical. Verify compatibility with the intended switching frequency and load characteristics before finalizing the design.
