Hi all, quick question about a PLA circuit I'm doing for coursework. I'll upload a pic of the circuit to help explain. I've got the main stuff worked out but a little line in the coursework is making me think if I need to add a couple of extra connections on it. The circuit has 7 incrementing values and 2 outputs. Basically, my first output is going to be 0,0 and so I originally thought that I wouldn't need any connections to the AND gate or to the OR gates, however I noticed my notes saying that the AND gate would float high and give a false 1 o/p from it. Now if it was connected straight to a single OR gate this would give a false o/p but I have to connect the AND and OR gate lines myself (as there are 2 o/p's) . My question is this - if I leave the lines unconnected would the OR gate input float high too? My notes say that the 'product line' (AND gate I/p line) would go high but says nothing about the 'product term' (OR gate I/p line). My notes say that to get round this we just connect both outputs of the buffer that go to the AND gate. Any ideas if I should just leave it in this situation or connect? Edit - Sorry this isn't in the homework help format,,it's been moved by admin.
