In summary, TI offers several I²C solutions for different application needs. The available I²C I/O expanders can be used for housekeeping duties and to enhance the feature set of an application while the I²C voltage level translators interface between low processor signals and higher voltage I²C I/O expanders. TI’s I²C multiplexers and switches can be used to support multiple applications at different voltage and/or frequency levels, resolve I²C address conflicts, and isolate a section on the I²C bus. Finally, I²C buffers and repeaters can provide I²C bus expansion, extend the I²C bus capacitance beyond 400pF, and allow I²C buses to operate at different voltages and frequencies.
