Digital Isolators Procurement Notes

Verify the specific suffix RL7 indicates reel packaging when sourcing. Confirm the 20-pin SSOP footprint matches the target PCB layout. Ensure the 2500 Vrms isolation rating meets system safety requirements. Check availability status as supply may be limited or restricted in certain regions. Validate that the 2.25V to 3.6V supply range aligns with the application power rails.

Digital Isolators Selection Notes

Select this component for applications requiring four isolated bidirectional channels. Consider the 2 Mb/s data rate limit for high-speed interface needs. Evaluate the 732 uA quiescent current against power budget constraints. Compare the 20-pin SSOP package size against available board space. Verify compatibility with the required logic levels and operating temperature range.
