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. Together with the

’ACT11240, this device provides the choice of various combinations of inverting and noninverting outputs.

The 74ACT11244 is characterized for operation from −40

°C to 85°C.
