Dual 4-to-1-line Data Selectors/Multiplexers (with 3-state outputs)
Description
Each of these data selectors/multiplexers contains inverters and drivers to supply full binary decoding data selection to the AND-OR-invert gates. Separate strobe inputs (G) are provided for each of the two fourline sections. The three-state outputs can interface with and drive data lines of bus-organized systems. With all but one of the common output disabled (at a high-impedance state) the low-impedance of the single enable output will drive the bus line to a high or low logic level. Each output has its own strobe (G). The output is disabled when its strobe is high.
