Enable/disable threshold is the VCC voltage at which the internal dc-to-dc converter is enabled/disabled.

To maintain data sheet specifications, do not draw current from VISO.

VCM 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.
