Note 2: The “Absolute Maximum Ratings” are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these
limits. The parametric values defined in the “Electrical Characteristics” table are not guaranteed at the absolute maximum ratings. The “Recommended Operating
Conditions” table will define the conditions for actual device operation.
Note 3: OFF state at a–g.
Electrical Characteristics
Over recommended operating free air temperature range (unless otherwise noted)
Note 4: All typicals are at V
Note 5: Not more than one output should be shorted at a time, and the duration should not exceed one second.
