description/ordering information
The ’AHC125 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 V through a pullup
CC
resistor; the minimum value of the resistor is determined by the current-sinking capability of the driver.
