Propagation delay skew represents the uncertainty of
where an edge might be after being sent through a digital
isolator. Figure 5 shows that there will be uncertainty in
both the data and clock lines. It is important that these
two areas of uncertainty not overlap, otherwise the clock
signal might arrive before all of the data outputs have
settled, or some of the data outputs may start to change
before the clock signal has arrived. From these consider-
ations, the absolute minimum pulse width that can be
