I2C MUX 2 Click Board

The I2C MUX 2 Click Board™ is a quad bidirectional translating I2C and SMBus switch with reset and interrupt functions, intended for applications with I2C slave address conflicts. It features a quad bidirectional translating switch controlled via the I2C bus, labelled as TCA9545A from Texas Instruments. Four interrupt inputs (INT3�INT0), one for each of the downstream pairs, are provided on the click board. One interrupt (INT) output acts as an AND of the four interrupt inputs. Click has two address jumpers, allowing up to four TCA9545A devices on the same bus. The I2C MUX 2 Click Board™ allows voltage translation between 1.8V, 2.5V, 3.3V, and 5V buses, and also supports hot insertion. The TCA9546A can work on a 0 - 400 kHz clock frequency range and is ideal for communication with numerous devices that share the identical slave address on the same bus. The I2C MUX 2 Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
