描述 Description

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.
