The SN74ALVC125PW is a quadruple Bus Buffer Gate with 3-state outputs and designed for 1.65 to 3.6V VCC operation. The SN74ALVC125 features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE)\ input is high. To ensure the high-impedance state during power up or power down, OE\ should be tied to VCC through a pull-up resistor and the minimum value of the resistor is determined by the current-sinking capability of the driver.
