description/ordering information  
The SN74F126 bus buffer features independent  
line drivers with 3-state outputs. Each output is  
disabled when the associated output-enable (OE)  
input is low.  
8
GND  
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.
