SN54BCT244 . . . FK PACKAGE  
(TOP VIEW)  
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 ′BCT240  
and ′BCT241, 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.

The ′BCT244 is organized as two 4-bit buffers/line  
drivers with separate output-enable (OE) inputs.  
When OE is low, the device passes data from the  
A inputs to the Y outputs. When OE is high, the  
outputs are in the high-impedance state.  
The SN54BCT244 is characterized for operation  
over the full military temperature range of –55°C  
to 125°C. The SN74BCT244 is characterized for  
operation from 0°C to 70°C.
