description/ordering information  
The ’ABT126 bus buffer gates feature independent line drivers with 3-state outputs. Each output is disabled  
when the associated output-enable (OE) input is low.  
When V  
is between 0 and 2.1 V, the device is in the high-impedance state during power up or power down.  
CC  
However, to ensure the high-impedance state above 2.1 V, 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.
