Note 1: µDFN devices production tested at +25°C. Overtemperature limits are generated by design.
Note 2: All currents into the device are positive. All currents out of the device are negative. All voltages referred to device ground,
unless otherwise noted.
Note 3: ∆V_OD and ∆V_OC are the changes in V_OD and V_OC when the DI input changes states.
Note 4: The short-circuit output current applied 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.
(V_CC = +5V, T_A = +25°C, unless otherwise noted.)
