Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 10: Voltage characteristics,

Table 11: Current characteristics, and Table 12: Thermal characteristics 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.
