Notes: 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.

2. ∆VOD and ∆VOC are the changes in VOD and VOC, respectively, when the DI input changes state.

3. Maximum current level applies to peak current just prior to foldback-current limiting; minimum current level

applies during current limiting.

Note: The device is put into shutdown by bringing RE high and DE low. 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

600ns, the device is guaranteed to have entered shutdown.
