These octal buffers and line drivers 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 SN54ABT2240,  
SN74ABT2240A and ’ABT2244A, these devices  
provide the choice of selected combinations of  
inverting and noninverting outputs, symmetrical  
active-low output-enable (OE) inputs, and  
complementaryOEandOEinputs. Thesedevices  
feature high fan-out and improved fan-in.

The outputs, which are designed to sink up to  
12 mA, include equivalent 25-series resistors to  
reduce overshoot and undershoot.  
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. OE  
should be tied to GND through a pulldown resistor; the minimum value of the resistor is determined by the  
current-sourcing capability of the driver.  
The SN54ABT2241 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT2241 is characterized for operation from –40°C to 85°C.
