description  
This octal buffer and line driver/MOS driver is  
designed to drive the capacitive inputs of MOS  
devices and to improve the performance and  
density of 3-state memory address drivers, clock  
drivers, and bus-oriented receivers and  
transmitters. This device features high fan-out  
and improved fan-in.  
The SN74ALS2240 is characterized for operation  
from 0°C to 70°C.
