Design a Custom BoardAbout This Component
8-channel I2C bus multiplexer/switch that allows a single I2C master to communicate with multiple slave devices on separate bus segments. Reduces address conflicts by isolating up to eight different I2C buses. Commonly used in systems with multiple identical I2C peripherals or when I2C address conflicts prevent parallel device connection.
Package: TSSOP-24 (4.4×7.8mm) · 24 pins
Why does this need a breakout?
Hand-soldering 0.65mm pitch traces is difficult without proper equipment; a breakout board with standard 0.1in header spacing lets you breadboard-prototype and test these compact devices easily. Commonly used for I2C/SMBus I/O expanders and mixed-signal microcontrollers, this breakout eliminates fine-pitch soldering and allows rapid iteration during development.
