    Hey there,

    I have to build a circuit that finds the maximum of three binary numbers given. The circuit should go through all three inputs at once. I was wondering how to find the maximum of two binary numbers for example 1001, 0101. I don't need a solution i just need some tips/hints or any help to get me started is fine. thanks a lot

    You may want to take a look at the 8-bit magnitude comparator 74HC688.

    The IC for comparing the magnitudes of 2 four bit words is the 74LS85. That might give you a hint if you look at a data sheet.
