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:
V
OD
and
V
OC
are the changes in magnitude of V
OD
and V
OC
, respectively, when the DI input changes state.
Note 3:
Maximum and minimum current levels apply to peak current just prior to foldback-current limiting.
