description/ordering information
'ABT126 buffer gates feature independent line drivers with 3-state outputs. Each output disabled when associated output-enable (OE) input low. When between device high-impedance state during power power down. However, ensure high-impedance state above should tied through pulldown resistor; minimum value resistor determined current-sourcing capability driver. ORDERING INFORMATION
