TCA9517DR TI I2C Buffer | 8-SOIC | 2.3-5.5V, 2-Wire Bus

Product Overview

The TCA9517DR from Texas Instruments is a hot-swappable I2C bus buffer designed for bidirectional voltage-level translation and bus buffering. It supports both standard (100 kHz) and fast (400 kHz) I2C modes, enabling reliable communication in mixed-voltage systems. The device features a 2.3V to 5.5V supply range, making it suitable for a wide variety of applications. Its 8-SOIC package ensures compact integration.
