description/ordering information
These quadruple bus buffer gates feature independent line drivers with 3-state outputs. Each output is disabled
when the associated output-enable (OE
) input is high.
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.
