Procurement Notes
Verify the specific suffix 'XG' against official Isocom documentation to confirm pinout configuration and compliance standards. Ensure the selected component matches the required DIP-6 package dimensions and lead spacing for your PCB layout. Cross-reference datasheet specifications for CTR and isolation voltage to validate suitability for your circuit design requirements.
Selection Notes
Select this component when a standard phototransistor output isolator is required for general-purpose digital isolation. Consider the 5300 Vrms isolation rating for safety-critical applications. Evaluate the 20% minimum CTR to ensure adequate noise margin in your specific load conditions compared to higher gain alternatives.
