description  
This octal buffer and 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.  
13 2A2  
12 1Y4  
11 2A1  
GND 10  
The 25-resistors in the lower output circuit  
reduce ringing and eliminate the need for external  
resistors.  
The SN74F2244 is characterized for operation  
from 0°C to 70°C.
