Logic Output Optoisolators Procurement Notes

Verify the specific suffix '300E' to confirm the tube packaging format and RoHS compliance status as indicated by manufacturer documentation. Ensure the procurement order matches the exact PDIP-8 gull wing package type required for the target PCB footprint. Cross-reference the datasheet for any recent component acceptance notices or lifecycle status updates from Broadcom Limited before finalizing purchase orders.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high-speed performance is required. The totem pole output structure eliminates the need for external pull-up resistors, simplifying circuit design compared to open-collector variants. Consider the 5 MBd data rate limit and 3750 Vrms isolation rating against system requirements. Verify that the 5 mA forward current drive capability aligns with the source logic levels available in the application design.
