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