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 A (ambient temperature) is P D(MAX) = (T J(MAX) ? T A ) / ? JA . Exceeding the maximum allowable power
dissipation will result in excessive die temperature and the register will go into thermal shutdown.
Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k ? in series with 100pF.
