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 may involve abnormal working of the device.
