Im trying to figure out how to make a 1 bit adder from a 4:1 mux 54ls153. I understand from what people say that if you can make the truth table you can figure it out but that's where im stuck at. I have the truth table but just can't figure out how to impliment it. Appreciante any help you can offer truth table x y cin sum carry 0 0 0 0 0 0 0 1 1 0 0 1 0 1 1 0 1 1 0 1 1 0 0 1 0 1 0 1 0 1 1 1 0 0 1 1 1 1 1 1
taken from a previous post with the same question its been a while since ive done digital systems sorry i couldnt answer it , but at least i found the answer on the forums for you =]
Yeah i found that one and i don't know if im just being dumb or something but im having trouble grasping that
Arrange the inputs so the selection by the X & Y bits matches the desired condition from the truth table.
cool i figured out problem. I was basically thinking too hard into it. I was looking at the inside of mux trying to figure out how to get it to do what i want. So it's not so much that it is an adder but that you bacially give it cases and what to push to output for each case.
