Note 2: All devices 100% production tested at TA = +25°C. Specifications over temperature are guaranteed by design.
Note 3: All currents into the device are positive; all currents out of the device are negative. All voltages are referenced to ground,
unless otherwise noted.
Note 4: ÎVOD and ÎVOC are the changes in VOD and VOC, respectively, when the DI input changes state.
Note 5: Capacitive load includes test probe and fixture capacitance.
Note 6: Guaranteed by design; not production tested.
Note 7: The timing parameter refers to the driver or receiver enable delay, when the device has exited the initial hot-swap protect
state and is in normal operating mode.
