Stresses above 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
outside of those listed in the operational sections of this specification
is not implied. Exposure to any absolute maximum rating for extended
periods may affect device performance and reliability.
Note:
(1) Output shorted for no more than one second. No more than
one output shorted at a time.
D.C. OPERATING CHARACTERISTICS
