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 drives the bus line to a high or low logic level. Each output has its own output-enable () input. The output is disabled when is high.

The SN54ALS253 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS253 and SN74AS253A are characterized for operation from 0°C to 70°C.

 

 

Select inputs A and B are common to both sections.
