Logic Output Optoisolators Procurement Notes

Verify the specific suffix code on the component marking against the official Broadcom datasheet to confirm exact insulation voltage ratings and packaging variants. Ensure the procurement source provides valid RoHS compliance documentation as required by project specifications. Cross-reference the manufacturer part number with authorized distributor lists to avoid counterfeit components.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation with high-speed digital signaling is required. The wide operating temperature range makes it suitable for harsh industrial environments. Verify that the system's input current requirements do not exceed the specified 20 mA limit and that the load can be driven by the open-collector output structure.

Logic Output Optoisolators Part Context

This device belongs to the HCPL series of high-speed optocouplers from Broadcom Limited. It shares similar functional characteristics with other models in the family but is distinguished by its specific insulation voltage rating and hermetic sealing. The series is designed for applications demanding reliable signal transfer across isolated barriers.

Logic Output Optoisolators Replacement Considerations

HCPL-5631 offers identical speed and pinout but with a lower 1500 Vdc insulation rating.
