These data selectors/multiplexers SN54HC251 SN74HC251 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 (in 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 55C to 125C. The SN74HC251 is characterized for operation from 40C to 85 C. By Texas Instruments
