description/ordering information
The ’AHC126 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 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.
