SN74BCT244 Octal Buffers/Drivers

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 (.

Features

1, 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. 2Y1 G.
