Digital Isolators Procurement Notes

Verify the specific suffix 'EC' confirms AEC-Q100 automotive qualification and 5 kVrms isolation rating. Confirm the '-ISR' suffix indicates tape-and-reel packaging. Ensure the selected variant matches the required thermal dissipation capabilities for the target application environment.

Digital Isolators Selection Notes

Select this component when high channel density and integrated power conversion are required. It replaces optocouplers to reduce size and power consumption. Consider the 100 Mb/s speed limit and 18 ns delay for timing-critical designs. Evaluate the SOIC-Wide-16 footprint for PCB layout constraints.
