operation.  
CC  
The SN74AUCH240 is designed specifically to improve the performance and density of 3-state memory  
address drivers, clock drivers, and bus-oriented receivers and transmitters.  
This device is organized as two 4-bit buffers/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  
CC  
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.  
Activebus-holdcircuitryholdsunusedorundriveninputsatavalidlogicstate. Useofpulluporpulldownresistors  
with the bus-hold circuitry is not recommended.  
This device is fully specified for partial-power-down applications using I . The I circuitry disables the outputs,
