TCA9517DGKR TI I2C Buffer | 8-VSSOP | Level-Shifting, Hot-Swap

Product Overview

The TCA9517DGKR from Texas Instruments is a hot-swappable I2C bus buffer with level-shifting capability, designed to extend the I2C bus capacitance and enable bidirectional voltage translation between 1.2V, 1.8V, 2.5V, 3.3V, and 5V buses. Housed in a compact 8-VSSOP package, it provides robust signal integrity and supports hot insertion without corrupting the bus. Ideal for multi-voltage systems, it ensures reliable communication in noisy environments.

Detailed Technical Specifications

Key Features

• Bidirectional voltage level translation between 1.2V, 1.8V, 2.5V, 3.3V, and 5V buses
