Electrical characteristics

6.2

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 15: Voltage characteristics,

Table 16: Current characteristics and Table 17: 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.
