description  
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 ’ABT2241, 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.  
9 10 11 12 13  
The outputs, which are designed to sink up to 12 mA, include equivalent 25-Ω series resistors to reduce  
overshoot and undershoot.  
When V  
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 2.1 V, OE should be tied to V  
the minimum value of the resistor is determined by the current-sinking capability of the driver.  
through a pullup resistor;

The SN54ABT2244A is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT2244A is characterized for operation from –40°C to 85°C.
