Electrical ratings

Stresses above the absolute maximum ratings listed in Table 2. Absolute maximum ratings 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.
