SN74F240 八路缓冲器和线路驱动器

SN74F240 描述

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 (active-low output-enable) inputs, and complementary OE and inputs.

The ´F240 is organized as two 4-bit buffers/line drivers with separate output enable () inputs. When is low, the device passes data from the A inputs to the Y outputs. When 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
