Abstract
A transmission unit including a transmission switch and an injection current control circuit is provided. The transmission switch includes a plurality of n-MOS and p-MOS transistors connected to one another in parallel, and the injection current control circuit includes an injection current detection circuit that is arranged for being activated upon detection of an injection current in an output side or an input side of the transmission unit, the transmission unit further includes a bypass circuit arranged for being activated by the injection current detection circuit and further arranged for bypassing the injection current to a ground upon detection of the injection current. A multiplexer, and demultiplexer including such a transmission unit is also provided herein.
