Buffer/Line Driver 8-CH Inverting 3-ST Bipolar 20-Pin SOIC T/R

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 ´F241 and ´F244, 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 ´F240 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 SN74F240 is available in TI"s shrink small-outline package (DB), which provides the same I/O pin count and functionality of standard small-outline packages in less than half the printed-circuit-board area.The SN54F240 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74F240 is characterized for operation from 0°C to 70°C.
