Note 1
For VSUPPLY < 1.5 V the source current for min 0.8 * VDD is limited to 0.5 mA. It is good practice to
allow a 10 % voltage margin when running at maximum temperatures to allow for worse case process
variation.

Note 1
At low VDD_REF values and high temperatures, the sink current capability will be reduced.
Note 2
For VDD_IO1/2 < 1.5 V the source current for min 0.8 * VDD is limited to 0.8 mA.
Note 3
