Procurement Notes

Verify the specific suffix 'U' indicates the DIP-8 package variant when sourcing. Confirm RoHS compliance status through official Broadcom documentation. Ensure the ordering part number matches the required pinout and isolation specifications for your design. Cross-reference datasheet revisions to confirm electrical parameters remain consistent with your system requirements.

Selection Notes

Select this component when high-speed switching and strong drive current are required for isolated power stages. The integrated push-pull output reduces external component count compared to standard logic optocouplers. Consider the 3750 Vrms isolation rating for safety-critical industrial applications. Verify that the 16 mA forward current requirement aligns with your microcontroller or driver output capabilities.
