How can I get 5.0V FPGA digital signal output?

Hello, everyone. My name is Ray. My device is Max 7000 series, EPM7128SLC84-7. I need 5.0V timing clock, and I set all vccio and vccint at a level at 5.0V power supply. However, ...

Thank you, Actris.

I used some logic IC to pull-up the output of FPGA before, but there is rise/fall time limitation(10nS) in my application.

As a result, I change to use a 5V FPGA to get better transition performance.

Thanks for your kind reply.
