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. Taken together with the ′ABT2240  
and ′ABT2241, 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.

The outputs, which are designed to sink up to  
12 mA, include 25-Ω 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.  
The SN74ABT2244 is available in TI’s shrink small-outline package (DB), which provides the same I/O pin count  
and functionality of standard small-outline packages in less than half the printed-circuit-board area.  
The SN54ABT2244 is characterized for operation over the full military temperature range of –55°C to 125°C.  
The SN74ABT2244 is characterized for operation from –40°C to 85°C.
