Key benefits Strong control over many I2C devices: Eight multiplexers at each I2C address in the range 0x70 to 0x77 enable control of 64 identical I2C addressing sections, providing scalable routing for multiple devices. Simple data routing: To direct subsequent I2C transfers to a chosen port, you only need to write a single byte that selects the multiplex output number. Wide voltage compatibility: Compatible with both 3V and 5V logic levels, enabling reliable use with a broad range of microcontrollers and systems. Efficient multidevice management: Connect up to eight I2C devices that share the same address to a single microcontroller and manage command routing easily. How it works The device provides eight multiplex channels per address, with addresses available in the 0x70–0x77 range. This structure enables organized routing of I2C data to the desired channel. When preparing to communicate with a specific device, write one byte to select the corresponding multiplex output; subsequent I2C data is directed to that port. Compatibility and performance Voltage: Supports both 3V and 5V logic levels for flexible integration with common MCU platforms. Addressing: Uses the standard 0x70–0x77 address range to support multiple multiplexers on the same bus and to organize 64 separate addressing sections. Reliability: Designed to provide straightforward and repeatable channel selection, simplifying I2C bus management in multidevice configurations. Practical use scenarios Scenario 1: Sensor array with identical addresses Use eight identical sensors (for example, temperature sensors) that all have the same I2C address. Assign each sensor to a separate multiplexer channel and control routing from a single microcontroller. Scenario 2: I2C expander cluster Add up to eight identical I2C I/O expanders or other perdevice peripherals sharing the same address. Route commands to a specific device without changing hardware addresses. Scenario 3: Development and testing with identical devices In a lab or prototype setup, quickly switch between multiple identical devices to verify behavior, collect data, or validate firmware without rewiring hardware.
