Mikroe I2C MUX 4 Click contains a dual bidirectional translating switch dedicated for applications with I2C slave address conflicts. The board features the Texas Instruments TCA9543APWR Low Voltage 2-channel I2C Bus Switch with interrupt logic. The master SCL/SDA signals are directed to two downstream pairs, or channels, where either individual SCL/SDA channel. Both channels can be selected by setting the programmable control register. It has two interrupts and a Reset input which allows the TCA9543A to recover from a situation where one of the downstream I2C buses is stuck in a low state.
