Logic Output Optoisolators Procurement Notes

Verify the specific suffix '520E' against official Broadcom documentation to confirm reel packaging and RoHS compliance status. Ensure the procurement specification matches the required 8-pin DIP form factor and open collector output type. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and avoid counterfeit components.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation is required alongside high-speed data rates up to 10 Mb/s. The open collector output necessitates external pull-up resistors for proper logic level generation. Consider the 3750 Vrms isolation rating for applications requiring robust noise immunity and safety separation between low-voltage control circuits and higher-voltage loads.
