74253 Data Selectors/Mux

Each of these Schottky-clamped data selectors/multiplexers contains inverters and drivers to supply fully complementary,on-chip, binary decoding data selection to the AND-OR gates. Separate output control inputs are provided for each of the two four-line sections.The 3-STATE outputs can interface directly with data lines of bus-organized systems. With all but one of the common outputs disabled (at a high impedance state), the low impedance of the single enabled output will drive the bus line to a HIGH or LOW logic level. CityTech BD
