circuits can often be made more compact, which can be an important consideration in silicon implementations.

Negative voltages

By using a transmission gate to switch alternating voltages (e.g.: audio signal), the negative power supply potential must be lower than the lowest signal potential. This ensures that the substrate diode will remain non-conducting even at negative voltages. Although the transmission gate can still switch to logic voltage levels, there are special versions with integrated
