Note 1: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device

ground, unless otherwise noted.

Note 2:

Note 3: The short-circuit output current applies to peak current just prior to foldback-current limiting; the short-circuit foldback output

current applies during current limiting to allow a recovery from bus contention.

Note 4: Capacitive load includes test probe and fixture capacitance.

Note 5: Shutdown is enabled by bringing RE high and DE low or by bringing SHDN high. If the enable inputs are in this state for less

than 50ns, the device is guaranteed not to enter shutdown. If the enable inputs are in this state for at least 800ns, the device

is guaranteed to have entered shutdown.
