If you want to find out how much current an I/O can sink before you raise the voltage level
above Volmax, you can look at the Iol (output low current) curve in
and trace to the corresponding current value.
In the example in
Another common use of the I/V curve is to determine the voltage at the IOB depending on
the load.
For example, if you are driving a 24 mA load from CPLD, will you violate the input
thresholds?
Figure
2, if the Volmax is 0.5V, you can sink 21 mA.
