TCA9548A I2C Multiplexer 1-to-8 IC TSSOP24 - 10 Pack

If you need to control more than one device that uses the same I2C bus, then you need the TCA9548A I2C Multiplexer 1-to-8 IC from PMD Way (with free delivery, worldwide).

With a little simple coding the TCA9548A can direct your host microcontroller to one of eight separate I2C buses. 

Furthermore, the TCA9548A can also act as a level converter, so you can have varying device bus and operating voltages between 1.8 and 5V DC. 

Finally, the TCA9548A supports I2C hot-swap of bus devices, and supports the usual 400 kHz operating mode used by the majority of I2C bus devices. 

Please note - this is for ten of the ICs. We also offer the convenient breakout board.
