description/ordering information  
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.  
The SN74HC244 is organized as two 4-bit  
buffers/drivers with separate output-enable (OE)  
inputs. When OE is low, the device passes  
noninverted data from the A inputs to the Y outputs.  
When OE is high, the outputs are in the  
high-impedance state.
