Product Summary
The SN74ABT126NS is a bus buffer gate. It features independent line drivers with 3-state outputs. Each output is disabled when the associated output-enable (OE) input is low. When VCC is between 0 and 2.1 V, the SN74ABT126NS is in the high-impedance state during power up or power down. 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.
Parametrics
