description/ordering information

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.

resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
