Abstract
A USB switching circuit includes a first multiplexer, a second multiplexer coupled with the first multiplexer through transmission paths, and a voltage regulation circuit coupled with the first and second multiplexers. The first multiplexer distributes first data signals to the transmission paths according to first control signals. The second multiplexer distributes a second data signal to the transmission paths according to second control signals. The voltage regulation circuit sets a maximum voltage and a minimum voltage of the first data signals to corresponding to a common voltage. The maximum voltage of the first data signals is not higher than a maximum voltage of the second control signals, or the minimum voltage of the first data signals is not lower than a minimum voltage of the second control signals. The first data signals and the second data signal are generated according to different communication protocols.
