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.
