Overview
The SN74ABT125DR is a quadruple bus buffer gate produced by Texas Instruments. This device features four independent line drivers with 3-state outputs, making it suitable for a variety of digital logic applications. Each output can be disabled when the associated output-enable (OE) input is high, allowing for flexible control over the output states. The SN74ABT125DR is fully specified for hot-insertion applications and includes Ioff and power-up 3-state support to prevent damaging current backflow and driver conflict during power transitions.
