I'm trying to implement four functions using a minimum number of 2:1 and 4:1 muxes with NO additional gates.
This is my truth table:
Right now, I'm currently working on function Z.
I grouped the rows into pairs accordingly:
When ABC=000, Z = D
When ABC=001, Z = D
When ABC=010, Z = D
When ABC=011, Z = D
When ABC=100, Z = D'
When ABC=101, Z = D'
When ABC=110, Z = D'
When ABC=111, Z = D'
So therefore I would need a mux with 8 data inputs?
I put two 4:1 muxes together, with the select inputs labeled with A, B, C
And I just labeled the data inputs by D.H (high), or D.L (low) according to the pairs above
This is what I have so far for function Z.
I really don't know how to label the pins or make the connections to connect both muxes together. Could someone please help me on this?
Edit:
I edited the above circuit to this one. But I still don't know how to cascade several muxes. I don't know where to connect the select inputs and other connections. Could someone please help me asap?
