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?
