SI8663BB-B-IS1R

Digital Isolators Overview

The SI8663BB-B-IS1R is a unidirectional digital isolator from the Si866x series, manufactured by Skyworks Solutions Inc. It features six channels (three forward and three reverse) with capacitive coupling technology. The device supports data rates up to 150 Mb/s and offers an insulation voltage of 2500 Vrms. Operating on a supply voltage range of 2.375 V to 5.5 V, it exhibits a propagation delay of 8 ns and rise/fall times of 4 ns. Certified under AEC-Q100 for automotive applications, it functions within a temperature range of -40°C to +125°C and is housed in a 16-lead SOIC-Narrow package.

Digital Isolators Feature Summary

• Capacitive coupling isolation technology ensures high reliability and immunity to magnetic fields.
• AEC-Q100 qualification confirms suitability for demanding automotive electronic environments.
• Unidirectional signal transmission provides precise channel separation between input and output sides.

Digital Isolators Applications

• Automotive powertrain control systems requiring isolated signal interfaces
• Industrial motor drive gate driver circuits
• General-purpose isolated communication links

Digital Isolators Procurement Notes

Verify that the specific part number matches the required SOIC-Narrow-16 package configuration. Confirm that the AEC-Q100 automotive qualification aligns with project specifications. Ensure the unidirectional channel arrangement meets system design requirements before procurement.

Digital Isolators Selection Notes

Select this component when high-speed data transfer at 150 Mb/s is necessary alongside robust galvanic isolation. The wide operating supply voltage range allows compatibility with various logic levels. Consider the thermal performance and package constraints for integration into compact assemblies.

Digital Isolators Part Context

This device belongs to the Si86xx family of digital isolators, designed to replace traditional optocouplers. It utilizes Skyworks' proprietary CMOS process to deliver superior performance metrics including lower power consumption and faster response times compared to legacy isolation technologies.

Digital Isolators Replacement Considerations

SI8663BB-B-IS1 is the tube-packaged equivalent of this reel-based component. SI8663AB-B-IS1R is available but operates at a significantly lower data rate of 1 Mb/s.
