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
devices are available in QSOP packages. Two speed grade options (1 and
150 Mbps) are available and achieve worst-case propagation delays of less
than 10 ns.
