SI8662BB-B-IS1R

Digital Isolators Overview

The SI8662BB-B-IS1R is a six-channel digital isolator from the Si866x series, manufactured by Skyworks Solutions. It utilizes capacitive coupling technology to provide electrical isolation with a rated insulation voltage of 2500 Vrms. The device supports unidirectional signal transmission at data rates up to 150 Mb/s. It operates within a supply voltage range of 2.5 V to 5.5 V and features a typical propagation delay of 10 ns. The component is housed in a 16-pin SOIC-Narrow package and is qualified under AEC-Q100 standards for automotive applications.

Digital Isolators Feature Summary

• Six independent unidirectional channels for high-density signal isolation
• Capacitive coupling architecture ensuring robust common-mode transient immunity
• AEC-Q100 qualification for reliability in automotive environments

Digital Isolators Applications

• Automotive electronic control units requiring galvanic isolation
• Industrial communication interfaces such as CAN and LIN buses
• Power conversion systems needing feedback loop isolation

Digital Isolators Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm channel configuration and speed grade. Ensure the ordering part number matches the required isolation voltage and package type. Confirm RoHS compliance status through the manufacturer's current datasheet before finalizing procurement specifications.

Digital Isolators Selection Notes

Select this component when six isolated channels are required for unidirectional data transfer. The 150 Mb/s speed rating suits high-frequency industrial protocols. Consider the 16-pin narrow SOIC footprint for space-constrained PCB layouts. Verify thermal dissipation requirements given the 415 mW power handling capability.

Digital Isolators Part Context

This part belongs to the Si866x family of digital isolators, which offers various channel counts and speed grades. The SI8662 variant specifically provides six channels, distinguishing it from four-channel or eight-channel siblings in the same series. It serves as a general-purpose isolation solution for mixed-signal circuits.

Digital Isolators Replacement Considerations

Check Skyworks datasheets for direct pin-compatible alternatives within the Si866x series that match the 150 Mb/s speed and 2500 Vrms isolation rating.
