SI86S640EE-IS2

Digital Isolators Overview

The SI86S640EE-IS2 is a six-channel digital isolator from the Si86S6x series, manufactured by Skyworks Solutions Inc. It features capacitive coupling isolation with a rated insulation voltage of 6.0 kVrms. The device supports unidirectional signal transmission across all channels and operates within a supply voltage range of 2.25 V to 5.5 V. It is qualified under AEC-Q100 standards for automotive applications and functions reliably in temperatures ranging from -40°C to +125°C.

Digital Isolators Feature Summary

• Six independent unidirectional signal channels
• High-voltage capacitive coupling isolation
• Automotive-grade reliability qualification
• Wide operating temperature range

Digital Isolators Applications

• Automotive powertrain control systems
• Industrial motor drives
• Grid-tied solar inverters
• Medical equipment interfaces

Digital Isolators Procurement Notes

Verify the specific suffix IS2 against official Skyworks documentation to confirm package type and tape-and-reel specifications. Ensure the component meets AEC-Q100 requirements if used in automotive contexts. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Confirm humidity sensitivity levels prior to surface-mount assembly processes.

Digital Isolators Selection Notes

Select this component when high channel density and robust galvanic isolation are required in space-constrained designs. The six-channel configuration reduces board space compared to using multiple dual-channel isolators. Verify that the unidirectional nature aligns with the system's data flow requirements. Ensure the 6.0 kVrms insulation rating exceeds the working voltage of the isolated circuit boundaries.

Digital Isolators Part Context

This device belongs to the Si86S6x family of multi-channel digital isolators. It shares the core capacitive isolation technology found in other Skyworks isolators but offers increased channel count. The SOIC-WB-16 package provides wide-body spacing for enhanced creepage and clearance distances, supporting high-voltage isolation standards.

Digital Isolators Replacement Considerations

Check for direct substitutes within the Si86S6x series such as the SI86S642EE-IS2, noting differences in channel count. Verify pinout compatibility before replacing existing designs. Ensure any alternative maintains the same AEC-Q100 qualification status for automotive applications.
