Absolute maximum ratings

This product contains devices for protecting the inputs against damage due to high static

voltages, however it is advisable to take normal precautions to avoid applying any voltage

higher than the specified maximum rated voltages. For proper operation it is recommended

Power considerations

where:

RthJA = Package thermal resistance (junction-to ambient)

Stresses above those listed as “absolute maximum ratings” may cause permanent damage

to the device. This is a stress rating only and functional operation of the device at these

conditions is not implied. Exposure to maximum rating for extended periods may affect

device reliability.

Warning:

the device in case of program counter corruption (due to

unwanted change of the I/O configuration). To guarantee safe

conditions, this connection has to be done through a typical

10k

Ω pull-up or pull-down resistor.
