Datasheet

Note 1: Devices production tested at +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: 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 3: ∆V
OD
and ∆V
OC
are the changes in V
OD
and V
OC
, respectively, when the DI input changes state.
Note 4: The maximum current applies to peak current just prior to foldback current limiting.
Note 5: Guaranteed by design; not production tested.
