Abstract: Switch circuits are disclosed, for providing a single-ended and a differentially switched high-voltage output signals by switching a high supply voltage in response to at least one logic-level control signal. The switch that provides the single-ended switched high-voltage output signal includes a chain of at least three serially coupled field effect transistors (FETs). The chain receives the high supply voltage and switches it to output the high-voltage output signal. The switch that provides the differentially switched high-voltage output signal includes two differentially coupled chains, each having at least three serially coupled FETs. The chains receive the high supply voltage and switch it to output the differential high-voltage output signal. A control/bias circuit provides a control voltage to at least one of the FETs in the chains, responsive to the control signal.
