Procurement Notes

Verify the specific package type and pinout configuration against the official datasheet before integration. Confirm that the operating temperature range of -20°C to +75°C meets the environmental requirements of the target application. Ensure that the 66mm isolation distance aligns with safety clearance standards. Cross-reference the manufacturer part number with the latest product change notifications to confirm component availability and revision status.

Selection Notes

Select this component when fiber optic isolation is required to achieve high noise immunity over a fixed physical separation. The side-looking geometry dictates specific mechanical alignment constraints during assembly. Consider the 20 mA forward current requirement for driver circuit design. Evaluate the -20°C lower temperature limit against ambient conditions. This device is appropriate for applications demanding galvanic isolation between logic-level signals without electrical conductivity.
