DESCRIPTION/ORDERING INFORMATION
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.
