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.

magnitude is the range over which the common mode is slewed.
Input enable time is the duration from when V
transitions. If an input data logic transition within a given channel does occur within this time interval, the output of that channel reaches the correct state within the
much shorter duration as determined by the propagation delay specifications within this data sheet. Input disable time is the duration from when V

present. The supply current associated with an individual channel operating at a given data rate can be calculated as described in the Power Consumption section.
See Figure 8 through Figure 10 for information on per-channel supply current as a function of data rate for unloaded and loaded conditions. See Figure 11 through

Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 8 through Figure 10 for information
on per-channel supply current for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating the per-channel supply current
for a given data rate.
