Description  
Silicon Lab's family of ultra low power digital isolators are CMOS devices  
that employ an RF coupler to transmit digital information across an isolation  
barrier. Very high speed operation at low power levels is achieved. These  
parts are available in 16-pin wide body and narrow body SOIC packages.  
Two speed grade options (1 and 150 Mbps) are available and achieve typical  
propagation delay of less than 10 ns.
