TCA9802DGKT TI I2C Buffer | 8-VSSOP | 2-Channel, 1.65-3.6V

Product Overview

The TCA9802DGKT from Texas Instruments is a dual-channel I2C buffer with hot-swap capability, designed to extend the I2C bus length and enable communication in multi-voltage systems. It operates over a wide supply voltage range of 1.65V to 3.6V, making it suitable for low-power and mixed-voltage applications. The device provides bidirectional voltage-level translation and bus buffering, ensuring robust data transmission in noisy environments. Packaged in a compact 8-VSSOP, it is ideal for space-constrained designs.
