description/ordering information
These octal buffers/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 ’ACT244 devices are organized as two 4-bit buffers/drivers with separate output-enable (OE) inputs. When
OE is low, the device passes noninverted 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.
