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.
