These octal buffers and line drivers are designed  
specifically to improve the performance and  
density of 3-state memory address drivers, clock  
drivers, and bus-oriented receivers and  
transmitters.

The ’AC244 are 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.
