Overview
The SN74LVC2G125DCURE4, produced by Texas Instruments, is a dual bus buffer gate with 3-state outputs. This device is designed to operate within 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 (OE) inputs, allowing the outputs to be disabled when the OE input is high. The device is packaged in a VSSOP (8-pin) package and utilizes NanoFree™ package technology, which uses the die as the package, enhancing packaging efficiency.
