Overview
The SN74LVC2G125DCUR is a dual bus buffer gate with 3-state outputs, produced by Texas Instruments. This device is designed for operation over a wide voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features dual line drivers with output enable control, allowing the outputs to be disabled when the associated output-enable (OE) input is high. The device is packaged in a VSSOP (8-pin) package and utilizes Texas Instruments' NanoFree™ package technology, which enhances packaging efficiency by using the die as the package itself.
