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. Together with the BCT241 and BCT244 devices, 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.
To ensure the high-impedance state during power up or power down, (OE) should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
