TCA9802DGKR TI I2C Buffer | 8-VSSOP | 2-Channel, 1.65-5.5V

Product Overview

The TCA9802DGKR from Texas Instruments is a dual-channel I2C buffer with hot-swap capability, designed to extend the I2C bus length and provide capacitive isolation. It operates over a wide supply voltage range of 1.65V to 5.5V, making it suitable for multi-voltage systems. The device features two bidirectional buffers that allow for bus expansion and level shifting, while maintaining I2C bus compatibility. Packaged in a compact 8-VSSOP, it is ideal for space-constrained applications.
