SI86S641HC-IS1R

Digital Isolators Overview

The SI86S641HC-IS1R is a Skyworks Solutions digital isolator featuring four unidirectional channels with capacitive coupling technology. It provides an insulation voltage of 3750 Vrms and supports data rates up to 10 Mbps. The device includes a common-mode transient immunity rating of 150 kV/µs. It operates within a supply voltage range of 2.5 V to 5.5 V and functions across a temperature range of -40°C to +125°C. Packaged in a 16-pin SOIC (0.154 inch width), it is designed for robust signal isolation in demanding environments.

Digital Isolators Feature Summary

• Four-channel unidirectional digital isolation using capacitive coupling
• High common-mode transient immunity for noise rejection
• Wide operating temperature range suitable for industrial applications

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Power electronics control circuits
• Automotive electronic modules

Digital Isolators Procurement Notes

Verify the specific suffix IS1R indicates reel packaging when ordering. Confirm that the HC variant meets the required insulation standards for your application. Check current availability as automotive-grade components may have restricted distribution channels. Ensure compatibility with your system's voltage levels before procurement.

Digital Isolators Selection Notes

Select this component when high-speed unidirectional isolation is needed alongside robust transient immunity. Compare against standard Si864x series if lower isolation voltage suffices. Consider the SOIC-16 footprint constraints during PCB layout. Verify AEC-Q100 qualification status if used in strict automotive environments.

Digital Isolators Part Context

This part belongs to the Si86S6x family of automotive-grade digital isolators from Skyworks Solutions. It complements other devices like the SI86S640BC by offering specific channel configurations and performance metrics tailored for high-reliability interfaces. The family emphasizes low power consumption and high durability.

Digital Isolators Replacement Considerations

Direct substitutes include other parts within the Si86S6x family such as the SI86S641FC-AS1, provided pinout and electrical specifications match. Verify package dimensions and thermal characteristics before swapping.
