Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 23: Voltage characteristics,

Table 24: Current characteristics, and Table 25: 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.
