Description: This octal buffer and line driver is designed specifically to improve both the performance and density...
This octal buffer and line driver is 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 SN64BCT240 and SN64BCT241, 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.
The SN64BCT244 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 outputs are in a high-impedance state during power up and power down while the supply voltage is less than approximately 3 V.
The SN64BCT244 is characterized for operation from 40°C to 85°C.
