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: ∆V
OD
and ∆V
OC
are the changes in V
OD
and V
OC
, 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 I
