DESCRIPTION/ORDERING INFORMATION  
This octal buffer/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.  
The SN74LV244AT is organized as two 4-bit buffers/line drivers with separate output-enable (OE) inputs. When  
OE is low, the device passes data from the A inputs to the Y outputs. When OE is high, the outputs are in the  
high-impedance state.
