Description

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.
