Note 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. µDFN devices are production tested at +25°C. Overtemperature limits are guaranteed by design.
Note 2: ΔV_OD and ΔV_OC are the changes in V_OD and V_OC, respectively, when the DI input changes state.
Note 3: The short-circuit output current applies to peak current just prior to foldback current limiting. The short-circuit foldback output
current applies during current limiting to allow a recovery from bus contention.
