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
(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 kVRMS are safety
certified by UL, CSA, VDE, and CQC, and products in wide-body packages
support reinforced insulation withstanding up to 5 kVRMS.

Notes:
1. The nominal output impedance of an isolator driver channel is approximately 50 , ±40%, which is a combination of
the value of the on-chip series termination resistor and channel resistance of the output driver FET. When driving loads
where transmission line effects will be a factor, output pins should be appropriately terminated with controlled
impedance PCB traces.
2. tPSK(P-P) is the magnitude of the difference in propagation delay times measured between different units operating at
the same supply voltages, load, and ambient temperature.
3. Start-up time is the time period from the application of power to valid data at the output.
