Differential Signal Isolation
IL600-Series Isolators are ideal for isolating differential signals
because you have access to the input coils and do not need
input power to drive the signal across the barrier:

In this illustrative circuit, when the voltage at node Y is greater than the voltage at node Z there is a logic high at the OUT+ node and a low
on the OUT- node.
Outputs are reversed when the voltage at node Z is higher than the voltage
at node Y. Current-limiting resistors can be selected to ensure input coil
currents are at least ±5 mA and no more than ±10 mA.
