description/ordering information

The ’AHC126 devices are quadruple bus buer

gates 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.
