SN74ALVC244,pdf(OCTAL BUFFERS/DRIVERS)

This octal buffer/line driver is designed for 1.65-V to 3.6-V V_CC operaTIon.

The SN74ALVC244 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.
