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.
