description

These data selectors/multiplexers contain full binary decoding to select 1-of-8 data sources and feature strobe-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 single 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 OE\ is high.

The SN54HC251 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC251 is characterized for operation from -40°C to 85 °C
