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.
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.

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
Figure 15 for total V
