OCTAL BUFFERS/DRIVERS WITH 3-STATE OUTPUTS

These octal Buffers and Line Drivers SN54F240 SN74F240 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 TIs 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 55C to 125C. The SN74F240 is characterized for operation from 0C to 70C. By Texas Instruments
