description
The SN74AHC125Q is a quadruple bus buffer gate 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 V_CC through a pullup
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
