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. Enable inputs provide a single point control for
enabling and disabling output drive. Ordering options include a choice of
isolation ratings (2.5, 3.75 and 5 kV) and a selectable fail-safe operating mode
to control the default output state during power loss. All products >1 kV_RMS are
safety certified by UL, CSA, VDE, and CQC, and products in wide-body
packages support reinforced insulation withstanding up to 5 kV_RMS.
