SI86S642HE-IS2R

Digital Isolators Overview

The SI86S642HE-IS2R is a digital isolator from Skyworks Solutions Inc. featuring four unidirectional channels with 6.0 kVrms isolation voltage. It supports data rates up to 150 Mbps and offers common mode transient immunity of 150 kV/µs. The device operates within a supply voltage range of 2.375 V to 5.5 V, with propagation delays as low as 8 ns. Packaged in a 16-SOIC (0.295 inch width), it functions across temperatures from -40°C to +125°C.

Digital Isolators Feature Summary

• Provides robust 6.0 kVrms insulation for high-voltage separation
• Delivers high-speed signal transmission at 150 Mbps
• Ensures signal integrity with 150 kV/µs common mode transient immunity

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Power electronics interfaces such as motor drives
• Medical equipment needing safety-certified isolation

Digital Isolators Procurement Notes

Verify the specific suffix HE against official Skyworks documentation to confirm automotive qualification status and exact electrical tolerances. Ensure the IS2R designation matches the required reel packaging quantity and moisture sensitivity level for your assembly line processes. Cross-reference pinout configurations with the latest datasheet revision to prevent layout errors during integration.

Digital Isolators Selection Notes

Select this component when high isolation voltage and fast data rates are critical. Compare channel count and directionality requirements against alternative models in the Si86Sxx series. Evaluate thermal management needs given the SOIC package constraints. Confirm that the input/output logic levels align with the system's voltage domains before finalizing the design.

Digital Isolators Part Context

This part belongs to the Si86Sxx family of capacitive coupling digital isolators. It complements other variants like the SI86S642EE-IS2 by offering higher isolation ratings suitable for demanding environments. The series provides scalable solutions for interface isolation in complex electronic architectures.

Digital Isolators Replacement Considerations

Direct substitutes include SI86S642HE-AS2R for automotive-specific applications or SI86S642HE-IS2 for non-reel packaging. Verify compatibility with SI86S642HC-AS1 if lower isolation ratings are acceptable.
