    I am trying to find a way avoid using relays to switch two inputs. I currently using a 4dpt relay to swich them. Here is my setup
    input one has 4 signals
    input two has 4 signals
    output to 4 signals

    voltage shoud be 5v or 12v

    I am thinking of using analog switch ICs but dosn't know which one to use and how to make up a simple circuit. any helps will be appreicated.

    Hello,

    Did you already look at the 4066.
    There are 4 switches inside.
    Using 2 of them you can make your circuit.

    I am trying to use it to switch two different circuits, both has 4 signals.
    - circuit one is an RGBS type video signal
    - circuit two is an 4-wire touch screen signal

    See attached pic. I have two of these relay circuit to switch them now but I believe an analog swtich will do a better job and bring down the "size" too. I do not know much about ICs. but if I can have a diagram drawing, I know how to assemble them together. Would the CD4067 able to do the job for two separate circuits? or I have to use 2 CD4067 since they are 2 separate circuits?

    Looks like a good choice..could you check out my old relay circuit diagram on the next post to see if it's feasible to use 4066? Thanks for your help.
