It supports a data rate of 5 Mb/s with a propagation delay of 45 ns rise and 10 ns fall time. The device provides an isolation voltage of 1500 Vrms and operates within a temperature range of -55°C to +125°C. Forward current is 8 mA with a forward voltage of 1.3 V, while the output type is a photo IC capable of 15 mA output current. Power dissipation is rated at 200 mW.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction for enhanced environmental protection
• High common-mode transient immunity of 1 kV/µs
• Wide operating temperature range suitable for demanding conditions

Logic Output Optoisolators Applications

• Industrial control systems requiring galvanic isolation
• Power supply feedback loops
• Signal transmission across isolated ground planes

Logic Output Optoisolators Procurement Notes

Verify the specific suffix #300 corresponds to the hermetically sealed variant when sourcing. Confirm that the PDIP-8 package matches the PCB footprint requirements. Ensure the 1500 Vrms isolation rating meets the safety standards of the target application. Cross-reference the datasheet revision to confirm parameter consistency. Validate the operating temperature range against the environmental specifications of the end product.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing is required for reliability in harsh environments. The 5 Mb/s data rate suits moderate-speed digital signal isolation. Consider the 1500 Vrms isolation barrier for basic insulation needs. The wide temperature range allows operation in extreme industrial settings. Evaluate the 8 mA input current requirement against the driving circuit capabilities.

Logic Output Optoisolators Part Context

This part belongs to the Broadcom HCPL series of high-speed optocouplers. It shares the PDIP-8 form factor with other models in the family but differs in speed and isolation ratings. The hermetically sealed version distinguishes it from standard plastic-packaged variants. It serves as a specialized solution for applications demanding robust physical protection alongside electrical isolation.

Logic Output Optoisolators Replacement Considerations

HCPL-2631#300 offers higher speed (10 Mb/s) and higher isolation (3750 Vrms) but lacks hermetic sealing. HCPL-4731#300 provides photodarlington output for higher gain but operates at lower speeds (100 kb/s). Verify pinout compatibility and thermal characteristics when substituting.
