description/ordering information  
This SN74BCT2241 is designed specifically to  
improve both the performance and density of  
3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. Together with the  
’BCT2240 and ’BCT2244 devices, this device provides the choice of selected combinations of inverting and  
noninverting outputs, symmetrical active-low output-enable (OE) inputs, and complementary OE and OE  
inputs. This device features high fan-out and improved fan-in.  
To ensure the high-impedance state during power up or power down, OE should be tied to V through a pullup  
CC  
resistor and OE should be tied to GND through a pulldown resistor; the minimum value of the resistor is  
determined by the current-sinking/current-sourcing capability of the driver.
