Logic Function Selector?

  1. Feb 15, 2009 #1
    Hi,

    I'm trying to build a digital circuit that will perform one of three logic functions on a set of three inputs A B C based on the input value of a counter that counts mod-3 (00, 01, 10).

    I can use basic chips such as mux, demux, 555 timer, logical chips

    Thanks

    Look for the 74153. It is a data selector (TTL).

    Welcome to the PF, gastro. We do not do your homework/coursework for you here at the PF. You must post your own work on the problem, before we can offer any hints or tutorial thoughts.

    So please post your initial circuit attempts, and tell us what you know about the problem.

    what is the difference between digital circuit and integrated circuit(IC)?

    An integrated circuit can be either digital, analog, or mixed signal in nature.
