Silicon Labs Digital Isolators

Silicon Labs CMOS digital isolators are mixed-signal IC solutions that leverage Silicon Labs' superior isolation and high voltage expertise to enhance power system performance, flexibility, and reliability while reducing system size and cost. The entire isolation portfolio supports isolation voltages up to 5kV. Silicon Labs Si84xx digital isolators are the industry's highest-performance, easiest-to-use, and lowest-cost line of 2.5 to 5kVrms rated digital isolators. These digital isolators are 10 times more reliable than optocouplers. The Si86xx family is the industry's highest performing, widest channel count series of unidirectional and bidirectional isolators supporting up to reinforced 5kVrms isolation ratings. Based on Silicon Labs' patented CMOS isolation technology, Si86xx isolators enable robust operation in harsh industrial applications.
