ELECTRICAL
CHARACTERISTICS
*Notice: Stresses beyond those listed under “Absolute Maximum Rat-
ings” may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other
conditions beyond those indicated in the operational sections of the
ABSOLUTE MAXIMUM RATINGS*
specifications is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.
