Note 4: The Absolute Maximum Ratings are those values beyond which

the safety of the device cannot be guaranteed. The device should not be

operated at these limits. The parametric values defined in the Electrical

Characteristic tables are not guaranteed at the absolute maximum rating.

The “Recommended Operating Conditions” table will define the conditions

for actual device operation.

Note 5: IO Absolute Maximum Rating must be observed.

DC Electrical Characteristics (Supply Pins)

Over recommended range of supply voltage and operating free air temperature (unless otherwise noted).

VCC (5V) = 4.0V to 5.5V or VREG (3.3V) = 3.0V to 3.6V, VCCIO = 1.65V to 3.6V
