EPF6016QC240 VCCIO level query

As the FPGA(EPF6016QC240-3) powered up with 5V, am curious about the output voltage levels from the FPGA, are they going to be 5V outputs too ? Atleast from datasheet it shows they will be at 5V lev...

Hi,
there's more information about Voh in the datasheet, see Figure 18:

According to the diagram, Voh doesn't comply with 5V CMOS Vih requirements. Notices that there's only 5V TTL but no 5V CMOS Voh spec in operation conditions. It's most likely possible to raise Voh with an external pull-up resistor.
