Description
The Silicon Laboratories 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 an 8-pin narrow-body SOIC package. Three speed
grade options (1, 10, and 150 Mbps) are available and achieve typical
propagation delays of less than 10 ns.
