description

The 74ACT11258 is designed to multiplex signals from 4-bit data sources to 4-output data lines in bus-organized

systems. The 3-state outputs will not load the data lines when the output control pin (G) is at a high logic level.

The 74ACT11258 is characterized for operation from − 40

°C to 85°C.
