(1) Stresses beyond 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 beyond those indicated under the Electric Characteristics is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) Due to the low dissipated power in this device, it is assumed that TJ = TA.
