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 (OE) input is at
a high logic level.
The 74ACT11257 is characterized for operation from −40°C to 85°C.
