SN54BCT240 - Octal Buffers/Drivers With 3-State Outputs

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 V_CC through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
