These octal buffers and line drivers are designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters.
The ?ACT240 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE)\ inputs. When (OE)\ is low, the device passes inverted data from the A inputs to the Y outputs. When (OE)\ is high, the outputs are in the high-impedance state.
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.
