All voltages are relative to their respective ground.
Supply current values are for all four channels combined running at identical data rates. Output supply current values are specified with no output load present. The
supply current associated with an individual channel operating at a given data rate may be calculated as described in the Power Consumption section on page 20.
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 14 for total I
The minimum pulsewidth is the shortest pulsewidth at which the specified pulsewidth distortion is guaranteed.
The maximum data rate is the fastest data rate at which the specified pulsewidth distortion is guaranteed.
t

load within the recommended operating conditions.
Co-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels with inputs on the same side of
the isolation barrier. Opposing-directional channel-to-channel matching is the absolute value of the difference in propagation delays between any two channels
with inputs on opposing sides of the isolation barrier.
CM

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. See Power Consumption section on page 19 for guidance on calculating per-
channel supply current for a given data rate.
