Note 1: Stresses listed as the above “Absolute Maximum Ratings” may cause permanent damage to the device. These are for stress
ratings. Functional operation of the device at these or any other conditions beyond those indicated in the operational sections of the
specifications is not implied. Exposure to absolute maximum rating conditions for extended periods may remain possibility to affect
device reliability.
Note 2: Thermal Resistance is specified with the component mounted on a low effective thermal conductivity test board in free air at
T_A=25°C.
Note 3: Devices are ESD sensitive. Handing precaution recommended.
Note 4: The device is not guaranteed to function outside its operating conditions.
