  • ✔️ The I2C multiplexer switches 8 different I2C addresses in the range from 0x70 to 0x77. This allows up to 8 different devices with the same I2C address to be connected to the same I2C interface, with the TCA9548A acting as gatekeeper.
  • ✔️ Enables voltage level conversion between 1.8V, 2.5V, 3.3V, and 5V buses
  • ✔️ Operating voltage: 1.8V - 5V
  • ✔️ Clock frequency: 0 - 400 kHz

Product Description

The small I2C multiplexer PCA9548A allows the connection of up to

8 I2C devices. The multiplexer has 8 different I2C addresses, from 0x70 to 0x77. This can also be used to control 8 multiplexers, resulting in 64 different I2C addresses.

Using this PCA9548A expansion card is straightforward, and it can be used on a breadboard with capacitors and pullups and pulldowns.  Some headers are required, and once soldered in, you can plug it into a solderless breadboard. 

The operating voltage of 1.8V to 5V allows you to run the 8-channel multiplexer at any logic level.


  • Size: 20x30mm (0.8x1.2in)
  • 8 different I2C addresses
  • Operating voltage: 1.8V - 5V
  • Enables the voltage level implementation between 1.8V, 2.5V, 3.3V and 5V buses
  • Max. Clock frequency: 400 kHz
