- Choosing the Correct I2C Device for New DesignsPDF, 87 Kb, Datei veröffentlicht: Sep 7, 2016
The I2C bus is a very popular and powerful bus used for communication between a single (or multiple)master and a single (or multiple) slave device. In many applications there is a potential need for moreslave devices on the bus, isolation between similar addressed slaves, or a need for more I/Os. Theseneeds can be solved with an I2C buffer, switch, and I/O expander.The application note h - Maximum Clock Frequency of I2C Bus Using RepeatersPDF, 116 Kb, Datei veröffentlicht: May 15, 2015
