I have this little problem to create a Binary Encoder Decimal with program WinbreadBoard. The image was related to what I got to do.
The problem is that I do not know how to put it in digital protoboard. This is different ICs or is one? All these keys .. WinBreadboard only has the ABCD (and their negations)
If a single IC, where IC is this? How do I find? I suspect that is a NAND (Not AND).

It was recommended the following ICs: 7400, 7420 and 7430. But for sure I'm doing something wrong, because the LED panels show the values F and C, should be 0 and 0, since the bits are zero. \/

I wonder where I am wrong in this circuit.
Sorry, for my poor english.
Thanks for all.
