Description
Silicon Lab's family of ultra-low-power digital isolators are CMOS devices
offering substantial data rate, propagation delay, power, size, reliability,
and external BOM advantages when compared to legacy isolation
technologies. The operating parameters of these products remain stable
across wide temperature ranges throughout their service life. For ease of
design, only VDD bypass capacitors are required.
Data rates up to 150 Mbps are supported, and all devices achieve worst-
case propagation delays of less than 10 ns. All products are safety
certified by UL, CSA, and VDE and support withstand voltages of up to
2.5 kVrms. These devices are available in an 8-pin narrow-body SOIC
package.

    Si8410/20/21 2. Functional Description 2.1. Theory of Operation The operation of an Si84xx channel is analogous to that of an opto coupler, except an RF carrier is modulated instead of light. This simple architecture provides a robust isolated data path and requires no special considerations or initialization at start-up.
