1.4 Device Information

The TCA9847 and TCA9848 are in-band I2C controlled multiplexer and switch. The channel switching and toggling is controlled by the I2C bus that is also passed through the I/Os. Both TCA9847 and TCA9848 have 8-channels, but with mux and switch configurations. They work with a single supply of 1.65V to 3.6V and have voltage translating capabilities from 0.65V to 3.3V.

The TCA9847 and TCA9848 are also capable of operating at I2C Fast Mode Plus, which have a rated operating bandwidth of 1MHz to support higher speed signaling in I2C applications.
