Overview
The SN74LVC2G241DCUR is a dual buffer and line driver designed by Texas Instruments to enhance the performance and density of 3-state memory-address drivers, clock drivers, and bus-oriented receivers and transmitters. This device operates within a voltage range of 1.65 V to 5.5 V, making it versatile for various applications. It features the innovative NanoFree™ package technology, which uses the die as the package, reducing size and improving thermal performance.
The device is organized as two 1-bit line drivers with separate output-enable inputs (1OE, 2OE), allowing for precise control over the output states. It supports partial-power-down applications and includes Ioff circuitry to prevent damaging current backflow when powered down.
