Overview
The SN74LVC2G17QDCKRQ1, produced by Texas Instruments, is a dual Schmitt-trigger buffer designed for automotive and other high-reliability applications. This device operates over a wide voltage range from 1.65 V to 5.5 V, making it versatile for various electronic systems. It features two independent buffers with Schmitt-trigger inputs, which provide hysteresis to improve noise immunity. The device is packaged in a 6-pin SC70 (DCK) package and is fully specified for partial-power-down applications, ensuring low power consumption and preventing damaging current backflow when powered down.
