Logic Output Optoisolators Procurement Notes

Verify the specific suffix '100' confirms the bulk packaging format as documented by Broadcom. Ensure the Class K hermetic seal requirement aligns with your environmental specifications. Cross-reference the datasheet for exact pinout configurations and thermal management guidelines before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when high reliability and hermetic sealing are critical for long-term stability. The tri-state output is suitable for multi-drop bus architectures requiring isolation. Consider the 5 Mb/s speed limit against system requirements. The wide temperature range makes it appropriate for extreme industrial or automotive-grade environments where standard plastic packages may fail.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-520K series of high-speed optocouplers from Broadcom Limited. The series is designed for applications requiring robust isolation and fast switching speeds. The HCPL-520K-100 specifically denotes the hermetically sealed ceramic variant, distinguishing it from non-hermetic plastic versions within the same functional family.
