Quadruple 2-Line To 1-Line Data Selectors/Multiplexers With 3-State Outputs

 

Description

The 74ACT11257 is designed to multiplex signals from 4-bit data sources to four output data lines in bus-organized systems. The 3-state outputs do not load the data lines when the output-enable input is at a high logic level.

The 74ACT11257 is characterized for operation from -40°C to 85°C.
