description/ordering information
NC – No internal connection
These 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.
