SI8663BB-B-IS1

Digital Isolators Overview

The SI8663BB-B-IS1 is a six-channel digital isolator from the Si866x family, utilizing capacitive coupling technology. It features three forward and three reverse unidirectional channels within a 16-pin SOIC-Narrow package. The device supports data rates up to 150 Mb/s with a typical propagation delay of 8 ns and rise/fall times of 4 ns. It operates on supply voltages between 2.375 V and 5.5 V, providing an insulation voltage of 2500 Vrms. Certified under AEC-Q100, it functions reliably across temperatures from -40°C to +125°C.

Digital Isolators Feature Summary

• Capacitive coupling architecture for high-speed signal isolation
• AEC-Q100 qualified for automotive reliability standards
• Integrated shutdown functionality for power management

Digital Isolators Applications

• Automotive electronic control units
• Industrial motor drives
• General-purpose isolated communication interfaces

Digital Isolators Procurement Notes

Verify the specific suffix 'BB' confirms the 2500 Vrms insulation rating and narrow SOIC package configuration. Ensure the 'IS1' designation matches the required tube packaging format rather than tape-and-reel variants. Confirm AEC-Q100 qualification status aligns with target application requirements before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when bidirectional isolation is not required due to its unidirectional channel design. The 150 Mbps speed suits most standard industrial protocols. Consider the 16-SOIC-N package dimensions for PCB layout constraints. Verify that the 2500 Vrms isolation level meets system safety standards compared to higher-rated alternatives.

Digital Isolators Part Context

This part belongs to the Skyworks Si866x series of general-purpose digital isolators. It shares core architectural features with siblings like the SI8663BD-B-IS1 but differs in insulation voltage ratings and package width specifications. The series emphasizes low power consumption and high common-mode transient immunity.

Digital Isolators Replacement Considerations

SI8663BD-B-IS1 offers similar functionality but provides 5000 Vrms insulation instead of 2500 Vrms.
