Texas Instruments SN74AHCT244QPWRG4
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 SN74AHCT244Q is organized as two 4-bit buffers/line drivers with separate output-enable (OE)\ inputs. When (OE)\ is low, the device passes 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.
