Output current is determined by the pull-up resistance (Rpullup) and Vlogic voltage, refer to Figure 8-1. The output current will produce a output low voltage (VOL) from the comparator. In which VOL is proportional to the output current. Use Figure 6-3 to determine VOL based on the output current.
The output current can also effect the transient response. More will be explained in the next section.
