FK PACKAGE (TOP VIEW) t 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 of – 55°C to 125°C. The 74ACT11253 is characterized for operation from – 40°C to 85°C. 1 1C2 1C3 NC V CC 2C0 • • • 1C2 1 2 6 16 0 1 13 0 3 MUX EN 0 15 14 G 1 3 1Y 2 3 7 11 10 5 9 2Y 8 † This symbol is in accordance with ANSI/IEEE Std 91-1984 and IEC Publication 617-12.
