description
This octal buffer or line driver is designed specifically to improve both the performance and density of 3-state
memory address drivers, clock drivers, and bus-oriented receivers and transmitters. This device provides
inverting outputs and symmetrical active-low output-enable (OE) inputs. This device features high fan-out and
improved fan-in.
The 74ACT11240 is characterized for operation from −40
°C to 85°C.
