TI SN74AHCT244IPWRQ1

This octal buffer/driver is designed specifically to improve both the performance and density of 3 - state memory - address drivers, clock drivers, and bus - oriented receivers and transmitters. The SN74AHCT244 is organized as two 4 - bit buffers/line drivers with separate output - enable (OE(overline)) inputs. When OE(overline) is low, the device passes data from the A inputs to the Y outputs. When OE(overline) is high, the outputs are in the high - impedance state. To ensure the high - impedance state during power up or power down, OE shall be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current - sinking capability of the driver.
