LOW POWER SIX-CHANNEL DIGITAL ISOLATOR
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
