TCA9803DGKT TI I2C Buffer | 8-VSSOP | 1.65-3.6V, 4pF

Product Overview

The TCA9803DGKT is a high-performance I2C bus buffer from Texas Instruments, designed to extend the I2C bus capacitance and enable communication over longer distances or with more devices. It features two bidirectional buffers for SDA and SCL lines, operating from 1.65V to 3.6V. The device is housed in a compact 8-VSSOP package, making it ideal for space-constrained applications. With a low quiescent current and high noise margin, the TCA9803DGKT ensures reliable data transfer in noisy environments.
