All voltages are relative to their respective ground.
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.

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
until the output states are guaranteed to reach their programmed output levels, as determined by the CTRL logic state (see Truth Table – Table 9).
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
Figure 6 for information on the per-channel supply current as a function of the data rate for unloaded and loaded conditions. See Figure 7 through Figure 8 for total

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
on the per-channel supply current as a function of the data rate for unloaded and loaded conditions. See the Power Consumption section for guidance on calculating
the per-channel supply current for a given data rate.
