Note 2: Parameters are 100% production tested at T
A
= +25°C, unless otherwise noted. Limits 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 device
ground, unless otherwise noted.
Note 4: ΔV
OD
and ΔV
OC
are the changes in V
OD
and V
OC
, respectively, when the DI input changes state.
Note 5: The short-circuit output current is the peak current just prior to current limiting; the short-circuit foldback output current
applies during current limiting to allow a recovery from bus contention.
