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 over legacy isolation technologies. The operating

parameters of these products remain stable across wide temperature ranges

and throughout device service life for ease of design and highly uniform

performance. All device versions have Schmitt trigger inputs for high noise

immunity and only require VDD bypass capacitors.

Data rates up to 150 Mbps are supported, and all devices achieve propagation

delays of less than 10 ns. Ordering options include a choice of isolation ratings

(3.75 and 5 kV) and a selectable fail-safe operating mode to control the default

output state during power loss. All products >1 kVRMS are safety certified by

UL, CSA, and VDE, and products in wide-body packages support reinforced

insulation withstanding up to 5 kVRMS.
