摘要：Problem to be solved: to provide a communication system capable of increasingthe number of slave devices to be inserted into the I2C bus which can be connected tothe I2C bus. The unit 21-2n connected to the CPU 1, which is a slave device, is connectedto the CPUAs a measure of surge voltage at the time of line insertion of the unitA
communication system comprising a zener diode D which functions as an overvoltageprotection circuit between an I2C bus 3 and a GND terminal;A switch SW is provided forcontrolling the interruption between the zener diode D and the GND terminal.The zenerdiode D has an anode connected to the I2C bus 3 and a cathode connected to the GNDterminal via a switch SW.Diagram
