Note 2: Applies to peak current. See Typical Operating Characteristics.
Note 3: The MAX1482/MAX1483 are put into shutdown by bringing R–—E– high and DE low. If the inputs are in this state for less
than 50ns, the parts are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are
guaranteed to have entered shutdown. See Low-Power Shutdown Mode section.
