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:

and
V

are the changes in V

and V

, respectively, when the DI input changes state.
Note 3:
The short-circuit output current applies to peak current just prior to foldback current limiting. The short-circuit foldback out-
put current applies during current limiting to allow a recovery from bus contention.
