Exceeding the absolute maximum rating may damage the device.
The device is not guaranteed to function outside its operating rating.
The maximum allowable power dissipation of any T
power dissipation will result in excessive die temperature.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
