    Hello,

    This looks like a homework help question.
    What did you do to look at the questions?

    Its 2 input and producing 4 outputs If you checkout sn74139 ic it will have a truth table to help you out. The 4 to 10 decoder is a sn7442 ic check out this will help . for example if the count is 0 0 1 0 will equal count 2
