Isolators - Gate Drivers Procurement Notes

Verify the specific suffix 'C' indicates the 2.5 kVrms isolation rating distinct from other variants. Confirm the 'ISR' suffix corresponds to the tape-and-reel packaging format. Ensure the component matches the 16-SOIC footprint requirements for your PCB layout. Cross-reference the datasheet revision date to confirm current specifications.

Isolators - Gate Drivers Selection Notes

Select this component when a dual-channel driver with 2.5 kVrms isolation is required for automotive or industrial use. Compare against the SI8233BD variant if higher 5 kVrms isolation is needed. Consider the 45 ns propagation delay for switching frequency requirements. Verify that the 16-SOIC package fits the available board space constraints.
