Logic Output Optoisolators Procurement Notes

Verify the specific suffix '360E' against official Broadcom documentation to confirm compliance with RoHS standards and specific packaging requirements. Ensure that the 3750 Vrms isolation rating aligns with your system's safety certification needs, as ratings vary across the HCPL-2611 family. Cross-reference the pinout configuration with your PCB design to prevent installation errors during assembly.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation exceeding standard optocoupler capabilities is required. The 10 MBd speed makes it suitable for applications where traditional pulse transformers are impractical. Consider the open-collector output topology for compatibility with LSTTL and TTL logic levels. Evaluate the 3750 Vrms isolation barrier against the voltage stress present in your specific application environment.

Logic Output Optoisolators Part Context

The HCPL-2611 series belongs to Broadcom's high-speed logic gate optocoupler family, designed for robust performance in noisy industrial environments.
