M MrUmunhum New Member Mar 13, 2009 #1 Hi group, I need an IC or circuit that will take two pins input and make a 4 state output. Something like this: Code: +-----------------+ | Input | Output | +-------+---------+ | A B | 1 2 3 4 | +-------+---------+ | 0 0 | 1 0 0 0 | | 1 0 | 0 1 0 0 | | 0 1 | 0 0 1 0 | | 1 1 | 0 0 0 1 | +-------+---------+ Any ideas?? Thanks for your time.
