SN74ACT244IDWREP

The SN74ACT244-EP octal buffer/driver is designed specifically to improve the performance and density of 3-state memory address drivers, clock drivers, and bus-oriented receivers and transmitters. The device is organized as two 4-bit buffers/drivers with separate output-enable (overline{OE}) inputs. When (overline{OE}) is low, the device passes noninverted data from the A inputs to the Y outputs. When (overline{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 (V_{CC}) through a pullup resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
