Channel-to-channel digital signal isolation is often required in PLCs and similar
applications where the reference ground of each channel may be different. Traditional
optocouplers, however, degrade performance by increasing timing parameters such
as PWD, propagation delay, and skew. IL600/IL600A Isolators provide excellent
channel-to-channel isolation with little timing degradation.
In addition to 2,500 Vrms input-to-output withstand voltage, IL600-Series
Isolators provide outstanding isolation of 400 Vrms between adjacent channels.
With two channels available in the tiny MSOP footprint, more functionality can
be crammed into a smaller space without sacrificing channel-to-channel or ground-to-ground
isolation.
As this diagram shows, the data line is powered by the signal, so no input power
supply is required:
