HCPL2611

Logic Output Optoisolators Overview

The HCPL2611 is a single-channel high-speed logic gate output optocoupler featuring an internal shield for superior common mode rejection. It integrates an AlGaAs LED with a high-gain integrated photodetector to provide electrical isolation. The device supports data rates up to 10 Mbps and operates within a temperature range of -40°C to +85°C. Key electrical parameters include a minimum common mode transient immunity (CMTI) of 10 kV/µs, a propagation delay of approximately 100 ns, and a maximum forward current of 20 mA. It utilizes an open-collector output capable of sinking at least 13 mA, ensuring TTL compatibility.

Logic Output Optoisolators Procurement Notes

Verify component status as this part may be obsolete or superseded by newer equivalents such as the HCPL26xxM series. Confirm manufacturer documentation for final design-in approval. Ensure sourcing channels provide valid traceability. Check for RoHS compliance markers on available stock. Validate that substitute parts meet all original electrical specifications before integration.

Logic Output Optoisolators Selection Notes

Select this component for applications requiring high-speed digital isolation with strong noise immunity. The open-collector output allows for wired-OR configurations. Ensure input current does not exceed maximum ratings to maintain longevity. Verify that the required data rate aligns with the 10 Mbps specification. Consider thermal management within the specified operating temperature limits.

Logic Output Optoisolators Part Context

This device belongs to the HCPL family of high-speed optocouplers designed for robust signal transmission across isolated boundaries. It shares architectural similarities with other members like the HCPL2601 but offers specific performance characteristics tailored for high-noise environments. The technology leverages advanced LED and photodetector integration to achieve fast switching speeds while maintaining strict isolation standards.

Logic Output Optoisolators Replacement Considerations

The HCPL2611 is obsolete. Recommended substitutes include the HCPL2611M from onsemi. Verify pinout compatibility and electrical parameter equivalence when transitioning to the replacement part number.
