These octal buffers/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 ’AHC244 devices are 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.

To ensure the high-impedance state during power  
up or power down, OE should be tied to V

through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking
