Si871x Digital Isolators

Silicon Labs' offers Si871x digital isolators providing a drop-in replacement solution for optocoupler isolators

Image of Silicon Laboratories' Si871x Digital IsolatorsSilicon Labs’ Si871x family of digital isolators provides a drop-in replacement solution for optocouplers. The Si871x devices provide superior noise immunity, more robust performance, and greater reliability than optocouplers. They are also the first optocoupler replacements based on mainstream CMOS technology and incorporating an innovative LED emulator front-end.

The Si871x isolators offer ideal configurations, packages, and footprints to replace a wide range of optocoupler products used in solar power inverters, switched mode power supplies (SMPS), uninterruptible power supplies (UPS), industrial drives, programmable logic controllers (PLC) and high-voltage medical equipment.
