† _{Stresses beyond those listed under absolute 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 beyond those indicated in the recommended operating conditions section of this
specification is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTE 1: For operation above 25°C, derate linearly at the rate of 9.2 mW/°C.
