All voltage values are measured with respect to the ground pin.2. The magnitude of the input signal must never exceed V + 0.3 V / GND - 0.3 V.CC3. The device is protected in case of over temperature by a thermal shutdown active @ 150 °C.4. Exceeding the power derating curves during a long period will cause abnormal operation. Table 2.
