Overview
The SN74ABT125DE4 is a quadruple bus buffer gate produced by Texas Instruments. This device features independent line drivers with 3-state outputs, making it suitable for various digital logic applications. Each output is disabled when the associated output-enable (OE) input is high, and the device is fully specified for hot-insertion applications using Ioff and power-up 3-state circuitry. This ensures that the outputs are in a high-impedance state during power up and power down, preventing driver conflict.
