These data selectors/multiplexers contain full binary decoding to select one-of-eight data sources and feature controlled complementary 3-state outputs.

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 the high-impedance state), the low impedance of the signal-enabled output drives the bus line to a high or low logic level. Both outputs are controlled by the output-enable (OE\) input. The outputs are disabled when is high.

The SN54ALS251 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74ALS251 is characterized for operation from 0°C to 70°C.

 

 

D0, D1,...D7 = the level of the respective D input
