All voltages are relative to their respective ground.
The supply current values for all four channels are combined when running at identical data rates. Output supply current values are specified with no output load
The minimum pulse width is the shortest pulse width at which the specified pulse-width distortion is guaranteed.
The maximum data rate is the fastest data rate at which the specified pulse-width distortion is guaranteed.
