SN74HC253 - Dual 4-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs

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 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 (in the 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 (OE)\ input. The outputs are disabled when their respective OE\ is high.
