DC General Purpose I/O Specifications
These tables list guaranteed maximum and minimum specifications for the voltage and temperature ranges: 3.0 V to 5.5 V and 
–40 °C = TA = 85°C, 2.4 V to 3.0 V and –40 °C = TA = 85 °C, or 1.71 V to 2.4 V and –40 °C = TA = 85 °C, respectively. Typical
parameters apply to 5 V and 3.3 V at 25 °C and are for design guidance only.
