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 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 worst-case
propagation delays of less than 10 ns. Ordering options include a choice of
isolation ratings (up to 5 kV) and a selectable fail-safe operating mode to control
the default output state during power loss. All products are safety certified by UL,
CSA, and VDE, and products in wide-body packages support reinforced insulation
withstanding up to 5 kVRMS.
