Texas Instruments TCA9847 1MHz 8-Channel I2C Multiplexer includes an SCL/SDA upstream pair that fans out to eight downstream pairs or channels. Any individual SCn/SDn channel can be selected, determined by the contents of the programmable control register. These downstream channels can be used to resolve I2C target address conflicts. One sensor can be connected to each channel (0-7) if eight identical digital temperature sensors are needed in the application.
