Mikroe I2C MUX 2 Click is a quad bidirectional translating I2C and SMBus switch with reset and interrupt functions. The device is intended for applications with I2C slave address conflicts. The I2C MUX 2 features the TI TCA9545A quad bidirectional translating switch controlled via the I2C bus. Four interrupt inputs (INT3–INT0), one for each of the downstream pairs, are provided on click board. One interrupt (INT) output acts as an AND of the four interrupt inputs.
