Description for the 74ACT11257
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.
