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 devices 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.  
SN54AC244 . . . FK PACKAGE  
(TOP VIEW)  
To ensure the high-impedance state during power  
up or power down, OE should be tied to V  
CC  
through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.
