Isolators - Gate Drivers Procurement Notes

Verify the specific suffix '100' corresponds to the DIP-8 trimmed package variant when ordering. Confirm RoHS compliance status and lead times directly with Broadcom Limited or authorized distributors, as availability may vary. Ensure the application environment supports the specified operating temperature range and isolation requirements before finalizing procurement.

Isolators - Gate Drivers Selection Notes

Select this component when hermetic sealing and high common-mode immunity are required for IGBT drivers. The open collector output suits applications needing external pull-up resistors. Consider the 500 ns propagation delay for switching speed requirements. Verify that the DIP-8 trimmed form factor fits the PCB layout constraints compared to standard DIP packages.
