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 ′F240 and ′F244, these devices provide the choice of selected combinations of inverting and noninverting outputs, symmetrical OE (acti.
