Answer 1

IC 74153 is a combination of two 4 to 1 MUX. The function given in the question has 4 bits A, B, C, and D, so at first, we need to convert 4 to 1 MUX to 8 to 1. In 4 bits A will be used as input and B, C and D will be used as a select line.

From the function given: F(A,B,C,D) = $\sum$(0,1,2,3,4,5,7,8,12) and Dont Care(d) = d(10,11)

So the implicit chart of the function is given below:

5

where D0 to D7 are the input of the MUX.

Circuit Diagram is given below:

Pin Diagram of select line A and B are 14 and 2 respectively.

Input A, B, C, and D will be connected to the inputs. Other than this we need to use NOT Gate and OR Gate.
