Note 1: All currents into the device are positive. All currents out of the device are negative. All voltages referred to device ground,
unless otherwise noted.
Note 2: This is a differential voltage from A to ꢂ that the driving device must see on the bus to disable its driver.
Note 3: The short-circuit output current applied to peaꢀ current just prior to foldbacꢀ current limiting. The short-circuit foldbacꢀ out-
put current applies during current limiting to allow a recovery from bus contention.
