Note 2.1 Stresses above those listed could cause permanent damage to the device. This is a stress
rating only and functional operation of the device at any other condition above those
indicated in the operation sections of this specification is not implied.
Note 2.2 For the 5V tolerant pins that have a pull-up resistor, the voltage difference between
V5VT_PIN and VDD must never exceed 3.6V.
Note 2.3 The Package Power Dissipation specification assumes a recommended thermal via design
consisting of a 2x2 matrix of 0.3mm (12mil) vias at 1.0mm pitch connected to the ground
plane with a 1.6 x 2.3mm thermal landing.
