1) All voltages values are measured with respect to the ground pin.

2) The magnitude of input signal must never exceed VCC + 0.3V / GND - 0.3V

3) 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, involves abnormal operating condition.
