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 DI changes state.

Note 3: Only one output shorted at a time.

Note 4: This input current 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 ILEAK.
