SI86S640FC-IS1R

Digital Isolators Overview

The SI86S640FC-IS1R is a Skyworks Solutions digital isolator featuring four unidirectional channels with capacitive coupling. It provides an isolation voltage of 3750 Vrms and supports data rates up to 10 Mb/s. The device exhibits a common-mode transient immunity of 150 kV/µs and operates within a supply voltage range of 2.25 V to 5.5 V. Packaged in a 16-pin SOIC-NB, it functions across temperatures from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides galvanic isolation via high-reliability capacitive coupling technology
• Supports high-speed data transmission with low propagation delay characteristics
• Ensures signal integrity through high common-mode transient immunity ratings

Digital Isolators Applications

• Industrial automation control systems
• Power monitoring and metering equipment
• Medical instrumentation interfaces

Digital Isolators Procurement Notes

Verify the specific suffix IS1R indicates reel packaging configuration distinct from tube variants. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Ensure the supplier source matches Skyworks official distribution channels to guarantee component authenticity and traceability for critical applications.

Digital Isolators Selection Notes

Select this model when four isolated bidirectional or unidirectional paths are required in a compact footprint. Compare against SI86S64x family members for package variations like SOIC-WB or QSOP. Validate that the 3750 Vrms rating meets system insulation requirements and that 10 Mb/s speed suffices for the application protocol.

Digital Isolators Part Context

This component belongs to the Si86S6x automotive-grade digital isolator series by Skyworks Solutions. It utilizes proprietary capacitive isolation technology to replace traditional optocouplers. The series offers improved performance metrics including higher CMTI and lower power consumption compared to legacy isolation solutions.

Digital Isolators Replacement Considerations

Direct substitutes include other SI86S64x variants such as SI86S640EE-AS2 or SI86S641FC-AS1, provided pinout compatibility and isolation voltage ratings align with the design requirements.
