Logic Output Optoisolators Procurement Notes

Verify the specific package variant required, as the base model number covers both through-hole and surface-mount versions. Confirm that the 3 mA forward current requirement aligns with your circuit design, as this is lower than standard optocouplers. Ensure compliance with RoHS directives if applicable to your manufacturing process. Check datasheet specifications for operating temperature ranges to validate environmental suitability.

Logic Output Optoisolators Selection Notes

Select this component when dual-channel isolation at 10 MBd is necessary. Consider the open-collector output structure for compatibility with pull-up resistor networks. Evaluate the 3 mA drive current against your source capabilities. Compare against the HCPL-2630 series if higher current drive or different packaging is preferred. Verify insulation voltage requirements against system safety standards.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-263x family of high-speed optocouplers from Broadcom. It shares architectural similarities with the HCPL-2630 but differs in drive current and package availability. The series is designed for applications requiring fast signal transfer with electrical isolation. It complements other Broadcom isolators offering varying speed and channel counts.
