COMMON-MODE TRANSIENT

IMMUNITY1

kV/μs

VCM = 1 kV, transient magnitude = 800 V

1 CM is the maximum common-mode voltage slew rate that can be sustained while maintaining specification-compliant operation. VCM 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.
