Silicon Lab's family of 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 a 16-pin wide body SOIC package. Three speed grade options (1, 10, 100 Mbps) are available and achieve typical propagation delay of less than 10 ns....
