Permanent device damage may occur if absolute maximum ratings are exceeded. This is a stress rating only and functional operation is not
implied at conditions other than those detailed in the operational sections of this data sheet. Exposure to absolute maximum ratlng conditions
for extended periods may affect device reliability.
The data sheet limits are not guaranteed if the device is operated beyond the operating ratings.
Due to the limited drive capability use for input of the same package only.
Package thermal resistance assumes exposed pad is soldered (or equivalent) to the devices most negative potential (GND) on the PCB.
Max. limit only applicable for short durations, not for continuous operation!
