Supply current values are for all channels combined running at identical data rates. Output supply current values are specified with no output load present. The supply
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

Dynamic supply current is the incremental amount of supply current required for a 1 Mbps increase in signal data rate. See Figure 4 through Figure 6 for information
current associated with an individual channel operating at a given data rate can be calculated as described in the Power Consumption section. See Figure 4 through
