Does GPIO output of DE0 nano depend on the load impedance

I am interfacing a NOT gate 7404 IC to GPIO of DE0 nano . Output of GPIO is driving the input of NOT gate. Will the input impedance of NOT gate have any effect on the transmitting value at the GPIO ...

I have done the assignment in pin planner and i have set the standard as 3.3 V and the 7404 IC supports this rating. Still the problem exists

Also I want to Interface the output from GPIO to a input of LPF made with resistor and capacitor. Which standard of I/O logic should be chosen while interfacing?
