description

The SN74AHCT126 device 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 low. When OE is high, 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 GND through a

pulldown resistor; the minimum value of the resistor is determined by the current-sourcing capability of the

driver.
