SN74AUC244的产品详情：

This octal buffer/driver is operational at 0.8-V to 2.7-V V_CC, but is designed specifically for 1.65-V to 1.95-V V_CC operation.

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.

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.

This device is fully specified for partial-power-down applications using I_off. The I_off circuitry disables the outputs, preventing damaging current backflow through the device when it is powered down.
