Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 14, Table 15, and Table 16

may cause permanent damage to the device. These are stress ratings only and functional

operation of the device at these conditions is not implied. Exposure to maximum rating

conditions for extended periods may affect device reliability.
