Procurement Notes

Verify the specific suffix 'T' or absence thereof against the manufacturer's latest documentation, as packaging variations may exist. Confirm RoHS compliance status directly with Broadcom Limited or authorized distributors. Ensure the SO-24 package dimensions match your PCB layout requirements. Check for any regional distribution restrictions or obsolescence notices before finalizing procurement plans.

Selection Notes

Select this component when high-speed isolation with significant current drive capability is required. The dual-channel configuration simplifies designs needing isolated control for half-bridge or full-bridge topologies. Consider the 5000 Vrms isolation rating for safety-critical applications. Evaluate the 7 ns propagation delay against system timing constraints. Ensure the 10A peak current meets the gate charge requirements of the target power devices.
