description
Each these data selectors/multiplexers contain inverters drivers supply full binary decoding data selection AND-OR gates. Separate output-control inputs provided each 4-line sections. 3-state outputs interface with drive data lines bus-organized systems. With common outputs disabled high-impedance state), impedance single enabled output drives line high logic level. Each output output-enable (OE) input. outputs disabled when their respective high.
