    I need a multiplexer which essentially works as a single pole/double
    throw (SPDT) switch with 5 switches controlled in parallell by a logic
    high/low signal.
    Here's an illustration I've made to explain it better:

    The signals to pass through the switches are video sync signals, a
    logic high/low signal and +12V. The voltage range would be from 0 to

    I've searched for SPDT multiplexers and come up with several hits, but
    it turns out that none of them actually work as SPDT switches. So the
    search continues.

  2. Search for video multiplexer IC, or just go to and pick the one you want. They
    have very basic, to computer controlled versions in a lot of
    input/output configurations.

    Service to my country? Been there, Done that, and I've got my DD214 to
    prove it.
