LVC125A Quadruple Bus Buffer Gate

This quadruple bus buffer gate is designed for 1.65-V to 3.6-V VCC operation. The SN74LVC125A device 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 pullup resistor; the min.
