SI8650AB-B-IS1

Digital Isolators Overview

The SI8650AB-B-IS1 is a general-purpose digital isolator from Skyworks Solutions Inc., featuring five unidirectional channels in a 16-SOIC package. It provides 2500Vrms isolation voltage and supports data rates up to 1 Mbps with a common-mode transient immunity of 35kV/µs. The device operates on a supply voltage range of 2.5V to 5.5V, ensuring reliable signal transmission across isolated boundaries without requiring start-up initialization.

Digital Isolators Feature Summary

• Capacitive coupling technology enables high-speed digital signal isolation
• Unidirectional channel configuration simplifies interface design
• Wide operating supply voltage range accommodates various logic levels

Digital Isolators Applications

• Industrial automation control systems
• Medical equipment signal isolation
• Power supply feedback loops

Digital Isolators Procurement Notes

Verify the specific suffix 'AB' against official Skyworks documentation to confirm the 2500Vrms isolation rating and 1Mbps speed class. Ensure the IS1 package variant matches the required 16-SOIC footprint. Cross-reference the manufacturer part number directly with authorized distributors to avoid counterfeit components.

Digital Isolators Selection Notes

Select this component when moderate speed requirements up to 1Mbps are sufficient for cost-sensitive applications. The 2500Vrms rating suits basic isolation needs compared to higher-rated variants like the BC or BD series. Consider the unidirectional nature for simple input-to-output signal transfer scenarios.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators, utilizing Skyworks' proprietary capacitive coupling technology. It offers a robust alternative to traditional optocouplers by providing faster switching speeds and lower power consumption while maintaining electrical safety standards.

Digital Isolators Replacement Considerations

For direct pin-compatible replacements within the same family, consider the SI8650BC-B-IS1 for higher 3750Vrms isolation or the SI8650ED-B-ISR for automotive-grade AEC-Q100 qualification. Verify that the replacement maintains the 1Mbps data rate requirement.
