FK PACKAGE (TOP VIEW) 1C2 1C3 NC V CC 2C0 description Each of these data selectors/multiplexers contains inverters and drivers to supply full 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 with and drive 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. Each output has its own strobe (G). The outputs are disabled when G is high. The 54ACT11253 is characterized for operation over the full military temperature range o...
