74ACT11253
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 mon 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.
