Codirectional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of the isolation
barrier.

Opposing directional channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on opposite sides of the
isolation barrier.

|CM| is the maximum common-mode voltage slew rate that can be sustained while maintaining V O > 0.7 × V DD1 or 0.7 × V ISO for a high input or V O < 0.3 × V DD1 or 0.3 × V ISO for a low
input. The common-mode voltage slew rates apply to both rising and falling common-mode voltage edges.
