description

This data selector/multiplexer contains full binary decoding to select one-of-eight data sources and features 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 a high-impedance state), the low-impedance of the enable output will drive the bus line to a high or low logic level. Both outputs are controlled by the strobe (G\). The outputs are disabled when G\ is high.

The 74AC11251 is characterized for operation from - 40°C to 85°C.
