SI8660BB-B-IS1R

Digital Isolators Overview

The SI8660BB-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 data rates up to 150 Mb/s and features unidirectional signal transmission across all channels. It operates within a supply voltage range of 2.375 V to 5.5 V and maintains functionality in temperatures from -40°C to +125°C. Packaged in a 16-pin SOIC-Narrow footprint, it is AEC-Q100 qualified for automotive reliability.

Digital Isolators Feature Summary

• Six independent unidirectional channels for high-density signal isolation
• Capacitive coupling architecture ensuring robust noise immunity
• Automotive qualification compliant with AEC-Q100 standards

Digital Isolators Applications

• USB Type-C and USB Power Delivery interface circuits
• Automotive electronic control units requiring galvanic isolation
• Industrial communication bus systems

Digital Isolators Procurement Notes

Verify the specific suffix IS1R indicates reel packaging configuration. Confirm the BB variant corresponds to the 2500 Vrms insulation rating and 150 Mbps speed class. Ensure compatibility with the required 16-pin SOIC-Narrow package dimensions for PCB layout integration.

Digital Isolators Selection Notes

Select this component when six isolated bidirectional or unidirectional paths are required in a single package. The 2500 Vrms rating suits general industrial and automotive applications where lower isolation stress exists compared to 3750 Vrms variants. Verify that the 150 Mbps data rate meets system timing requirements.

Digital Isolators Part Context

This part belongs to the Si866x family of high-speed digital isolators. It shares the same pinout and form factor as other members like the SI8662 and SI8663, differing primarily in insulation voltage ratings and channel configurations. The family is designed to replace traditional optocouplers in space-constrained designs.

Digital Isolators Replacement Considerations

SI8662BB-B-IS1R offers identical pinout but higher 3750 Vrms insulation. SI8663BB-B-IS1R provides mixed forward/reverse channel counts. Verify insulation requirements before substituting.
