TI SN74ACT244PWR

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.
