SI86S642EE-IS2

Digital Isolators Overview

The SI86S642EE-IS2 is a Skyworks Solutions Inc. digital isolator featuring four unidirectional channels with a maximum data rate of 150 Mbps. It provides high isolation voltage of 6.0 kVrms and operates within a supply voltage range of 2.25 V to 5.5 V. The device utilizes capacitive coupling technology for signal transmission across isolation barriers. It is housed in a 16-pin SOIC package and supports an operating temperature range from -40°C to +125°C. Key electrical specifications include a common-mode transient immunity of 100 kV/µs and propagation delays typical of 8 ns.

Digital Isolators Feature Summary

• High electromagnetic immunity due to capacitive coupling technology
• No startup issues ensuring reliable power-up sequencing
• Robust isolation barrier rated at 6.0 kVrms

Digital Isolators Applications

• Industrial automation systems requiring galvanic isolation
• Medical equipment needing high-voltage safety compliance
• Power electronics monitoring and control interfaces

Digital Isolators Procurement Notes

Verify the specific suffix EE-IS2 against official Skyworks documentation to confirm pinout and isolation ratings. Ensure compatibility with system voltage levels between 2.25 V and 5.5 V. Confirm that the 16-SOIC package dimensions meet PCB layout requirements. Check for AEC-Q100 qualification if automotive application is intended, as indicated by similar series parts.

Digital Isolators Selection Notes

Select this component when high isolation voltage (6 kVrms) and fast data rates (150 Mbps) are required. It is suitable for applications demanding high common-mode transient immunity. Consider the 16-pin SOIC form factor for space-constrained designs. Compare with lower isolation variants like the SI864x series if 6 kVrms is not necessary.

Digital Isolators Part Context

This part belongs to the Si86S6x family of digital isolators from Skyworks Solutions. The family focuses on high-reliability isolation solutions using proprietary capacitive coupling technology. These devices are designed to replace traditional optocouplers in modern electronic systems, offering improved performance and longevity.

Digital Isolators Replacement Considerations

SI86S642BC-AS1 is a documented substitute with 3.75 kVrms isolation. Verify isolation voltage requirements before substitution. Other family members may offer different channel counts or data rates.
