SPECIFICATIONS
All voltages are relative to their respective ground; 2.7 ≤ VDD1 ≤ 5.5 V, 4.5 V ≤ VDD2 ≤ 5.5 V. All minimum/maximum specifications apply
over the entire recommended operation range, unless otherwise noted. All typical specifications are at TA = 25°C, VDD1 = VDD2 = 5.0 V,
unless otherwise noted.

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.
