Maximum Ratings
(Above which the useful life may be impaired. For user guide-
lines, not tested.)
Note:
Stresses greater than those listed under MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of this
specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
