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
present. 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

is the maximum common-mode voltage slew rate that can be sustained while maintaining the output voltage (V

. CM
L
is the maximum common-
mode voltage slew rate that can be sustained while maintaining V
OUT
< 0.8 V. The common-mode voltage slew rates apply to both rising and falling common-mode
voltage edges. The transient 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.
