So i was using the 3 basic gates IC (7432, 7408 and 7404) and when i use the 7432 the output was always high but the inputs are low or simply, 0 + 0=1.why is this happening and how to solve it. I tried using different 7421 IC's yet with no changes. I would like know other tips as well inbreadbarding.
