Description
General part information
SN74BCT244 Series
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(active-low output-enable) inputs, and complementary OE andinputs.
The ´BCT244 is organized as two 4-bit buffers/line drivers with separate output-enable () inputs. Whenis low, the device passes data from the A inputs to the Y outputs. Whenis 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.
