_______________________________________________________________________________________
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:
VOD and VOC are the changes in VOD and VOC, respectively, when the transmitter input changes state.
Note 3: This input current level is for the hot-swap enable (EN_, EN, EN) inputs and is present until the first transition only. After the
first transition the input reverts to a standard high-impedance CMOS input with input current IIN. For the first 20s the input
current may be as high as 1mA. During this period the input is disabled.
Note 4: Maximum current level applies to peak current just prior to foldback-current limiting. Minimum current level applies during
current limiting.
