Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these
or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may affect
device reliability.

difference between devices = +30°C (Note 5)
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.
