1 Absolute Maximum Ratings
Stresses beyond these absolute maximum ratings listed below may cause permanent damage to the device.
These are stress ratings only; operation of the device at these or any other conditions beyond those listed in the operational sections of this document is not implied.
Exposure to absolute maximum rated conditions for extended periods may affect device reliability. Al voltages referred to GND. Currents flowing into terminals are positive, those drawn out of a terminal are negative. Table 1-1: AbsMaxRatingsTable
