V CM = 1 kV, transient magnitude = 800 V

CM is the maximum common-mode voltage slew rate that can be sustained while maintaining specification-compliant operation. V CM is the common-mode potential
difference between the logic and bus sides. The transient magnitude is the range over which the common-mode is slewed. The common-mode voltage slew rates
apply to both rising and falling common-mode voltage edges.
