OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

These octal Buffers and Line Drivers SN54BCT240 SN74BCT240 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 BCT241 and BCT244, 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. These devices feature high fan-out and improved fan-in. The BCT240 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 SN54BCT240 is characterized for operation over the full military temperature range of 55C to 125C. The SN74BCT240 is characterized for operation from 0C to 70C. By Texas Instruments
