ABSTRACT:
A switch means designed as an integrated circuit possesses two series-connected FETs (Q1P, Q2P; Q1N, Q2N) whose common switching point (N5, N6) is clamped via a clamp FET (Q3N, Q3P) to a reference potential. The conductivity type of the clamp FET (Q3N, Q3P) is opposite the conductivity type of the two series-connected FETs (Q1P, Q2P; Q1N, Q2N). In the case of an n-channel clamp FET (Q3N), the latter is connected to negative potential. In the case of a p-channel clamp FET (Q3P), it is connected to positive potential.
