Stresses beyond those listed under "absolute maximum ratings" may cause permanent damage to the device.These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions" is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
NOTES:1. The input and output negative-voltage ratings may be exceeded if the input and output clamp-current ratings are observed.
           2.The package thermal impedance is calculated in accordance with JESD 51-7.
           3.The package thermal impedance is calculated in accordance with JESD 51-5.


Description

The SN54ABT126 bus buffer gates feature independent line drivers with 3-state outputs. Each output of SN54ABT126is disabled when the associated output-enable (OE) input is low.When V_CC is between 0 and 2.1 V, the device 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.
