description  
The SN64BCT2244 is a noninverting octal buffer and line/MOS driver 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 SN64BCT2240 and SN64BCT2241, these devices provide the choice of  
selected combinations of inverting and noninverting outputs, symmetrical OE (active-low output-enable) inputs,  
and complementary OE and OE inputs. These devices feature high fan-out and improved fan-in.  
When the output-enable (1OE and 2OE) inputs are low, the device transmits data from the A inputs to the  
Y outputs. When 1OE and 2OE are high, the outputs are in the high-impedance state. Output-enable 1OE  
affects only the 1Y outputs; output-enable 2OE affects only the 2Y outputs.  
Theoutputs, whicharedesignedtosourceorsinkupto12mA, include33-seriesresistorstoreduceovershoot  
and undershoot.  
The SN64BCT2244 is characterized for operation from 40°C to 85°C and 0°C to 70°C.
