description

These data selectors/multiplexers contain inverters and drivers tosupply full binary decoding data selection to the AND-OR gates.Separate output-control inputs are provided for each of the two4-line sections.

The 3-state outputs can interface with and drive data lines ofbus-organized systems. With all but one of the common outputsdisabled (at a high-impedance state), the low impedance of the singleenabled output will drive the bus line to a high or low logic level.Each output has its own strobe (G\) inputs. The output is disabledwhen its strobe is high.

The SN54F253 is characterized for operation over the full militarytemperature range of -55°C to 125°C. The SN74F253 ischaracterized for operation from 0°C to 70°C.

Select inputs A and B are common to both sections.
