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 V
OD
and V
OC
, respectively, when the DI input changes state.
Note 3:
The SRL pin is internally biased to V
CC
/ 2 by a 100kΩ/100kΩ resistor divider. It is guaranteed to be V
CC
/ 2 if left
unconnected.
Note 4:
Maximum current level applies to peak current just prior to foldback-current limiting; minimum current level applies during
current limiting.
