MIKROE-4240

MIKROE-4240 is an I2C MUX 4 Click compact add-on board that contains a dual bidirectional translating switch dedicated for applications with I2C server address conflicts. This board features the TCA9543APWR, a low voltage 2-channel I2C bus switch with interrupt logic from Texas Instruments. The host SCL/SDA signals are directed to two downstream pairs, or channels, where either individual SCL/SDA channel or 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. This Click board™ is suitable to work with I2C interfaces for applications such as fault isolation, address conflict, level translation, or broadcast communication.

• Click board size S is 28.6 x 25.4mm
• Input voltage is 3.3V or 5V
