CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation
of the device at these or any other conditions above those indicated in the operational sections of this specification is not implied.
Operating Conditions at TA = FuIl Package-Temperature Range, Unless Otherwise specified. For maximum reliability, operating con-
ditions should be selected so that operation Is always within the following ranges:
