SN74AHCT125DR

The 'AHCT125 devices are quadruple bus buffer gates featuring independent line drivers with 3- state outputs. Each output is disabled when the associated output- enable (OE) input is high. When OE is low, the respective gate passes the data from the A input to its Y output. To ensure the high- impedance state during power up or power down, OE should be tied to VCC through a pullup resistor; the minimum value of the resistor is determined by the current- sinking capability of the driver.
