The TCA9548A device features eight bidirectional transfer switches that can be controlled through the I2C bus. The serial clock/serial data (SCL/SDA) upstream pair can be expanded to 8 downstream pairs or lanes. Depending on the contents of the programmable control registers, any single SCn/SDn channel or combination of channels can be selected. These downstream channels can be used to resolve I2C slave address conflicts. For example, if an application requires eight identical digital temperature sensors, one sensor can be connected to each channel (0-7).
In the event of a timeout or other improper operation, the system master can reset the TCA9548A by driving the RESET input low. Likewise, a power-on reset deselects all channels and initializes the I2C/SMBus state machine. Asserting RESET also enables reset and initialization without powering down the part. This allows recovery if one of the downstream I2C buses is stuck low.
The switch has a pass gate so that the VCC pin can be used to limit the maximum high voltage through the TCA9548A. Once the maximum high voltage is limited, different bus voltages can be used on each pair, allowing 1.8V, 2.5V or 3.3V parts to communicate with 5V parts without any additional protection. For each channel, external pull-up resistors pull up the bus voltage to the desired voltage level. All I/O pins are 5V tolerant.
