ESD Rating, All Pins, HBM
Note: 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 2.1 For the 5V tolerant pins that have a pull-up resistor, the pull-up voltage must not exceed
3.6V when the device is unpowered.
Note 2.2 The Package Power Dissipation specification assumes a thermal via design with the
thermal landing be soldered to the PCB ground plane with 0.3mm (12mil) diameter vias in
a 4x4 matrix at 0.9mm (35.4mil) pitch.
Note 2.3 Junction to Ambient (θJA) is dependent on the design of the thermal vias. Without thermal
vias and a thermal landing, the θJA is approximately 60°C/W including localized PCB
temperature increase.
