Adafruit LTC4316 I2C Address Translator

Effortlessly integrate multiple I2C devices with the Adafruit LTC4316 I2C Address Translator, a powerful solution for real-time address translation. Ideal for projects with limited unique I2C addresses, this chip ensures seamless compatibility and functionality without the need for an I2C multiplexer.

• Real-time I2C address translation with on-the-fly adjustments.
• Supports 4 address translation options via DIP switches.
• Customizable configurations with solderable XOR_LOW resistors.
• Compatible with STEMMA QT and SparkFun Qwiic connectors for quick, solderless connections.

Consider an AHT20 sensor with a fixed address of 0x38. Utilizing the translator, this device can appear at different addresses (e.g., 0x78, 0x58, or 0x48) to the I2C controller, allowing for flexible system designs. This approach streamlines the integration of multiple sensors without address conflicts.

Note the limitations such as lack of clock-stretching support, and ensure your firmware can accommodate address changes. Resetting the device is required after changing configurations. The design is particularly suitable for streamlined projects without complex clock-dependent chips.
