Note 1: All currents into the device are positive; all currents out of the device are negative. All
voltages are referred to device ground unless otherwise noted.
Note 2: ΔV_OD and ΔV_OC are the changes in V_OD and V_OC, respectively, when the DI input changes
state.
Note 3: Maximum current level applies to peak current just prior to fold back current limiting;
minimum current level applies during current limiting.
