This octal buffer/driver is operational at 0.8-V to 2.7-V VCC, but is designed specifically for 1.65-V to 1.95-V VCC operation.\n\n The SN74AUC244 is organized as two 4-bit 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.\n\n 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.\n\n This device is fully specified for partial-power-down applications using Ioff. The Ioff circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
