These data selectors/multiplexers contain 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 4-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\) inputs. The output is disabled when its strobe is high.
The SN54F253 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74F253 is characterized for operation from 0°C to 70°C.
Select inputs A and B are common to both sections.
