description/ordering information  
The ’BCT2244 devices are 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 devices and  
SN74BCT2241, these devices provide the choice  
of selected combinations of inverting and  
noninverting outputs, symmetrical active-low  
output-enable (OE) inputs, and complementary  
OE and OE inputs. These devices feature high  
fan-out and improved fan-in.

through a pullup resistor; the minimum value of  
the resistor is determined by the current-sinking  
capability of the driver.  
The outputs, which are designed to source or sink  
up to 12 mA, include 33-Ω series resistors to  
reduce overshoot and undershoot.
