Note 1: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to device
Note 2: ∆V
Note 3: Maximum current level applies to peak current just prior to foldback-current limiting; minimum current level applies during
Note 4: Shutdown is enabled by bringing RE high and DE low. If the enable inputs are in this state for less than 50ns, the MAX1481
