† Stresses beyond those listed under “absolute maximum ratings” may cause permanent damage to the device. These are stress ratings only, and

functional operation of the device at these or any other conditions for extended periods may affect device reliability.

NOTES:

1. All voltage values are with respect to network GND.

2. For operation above 25

°C free-air temperature, derate linearly at the rate of 9.3 mW/°C.
