Procurement Notes

Verify the specific suffix 'XL' against official manufacturer documentation to confirm pinout and electrical characteristics match requirements. Ensure compatibility with existing PCB footprints and thermal management strategies. Confirm that the through-hole DIP-4 package aligns with assembly processes. Cross-reference datasheet specifications for isolation voltage and current transfer ratio before integration.

Selection Notes

Select this component when single-channel isolation with moderate speed is required. Consider the 5300Vrms isolation rating for safety-critical applications. Evaluate the 4μs rise time against system timing constraints. Compare the DIP-4 form factor with available surface-mount alternatives if space is limited. Verify operating temperature range suitability for the target environment.
