SWITCHING CHARACTERISTICS (MAX13443E)
(VCC = +4.75V to +5.25V, TA = TMIN to TMAX, unless otherwise noted. Typical values are at VCC = +5V and TA = +25°C.)
Note 3:
ΔVOD and ΔVOC are the changes in VOD and VOC, respectively, when the DI input changes state.
Note 4: The short-circuit output current applies to peak current just before foldback current limiting. The short-circuit foldback out-
put current applies during current limiting to allow a recovery from bus contention.
