    Abstract: A switching circuit (10) for an ultrasound transmission channel (1) is inserted between a connection terminal (Xdcr) and a low voltage output terminal (LVout) and comprising a receiving switch (30) a high voltage clamp circuit (HV1) inserted between the connection terminal (Xdcr) and a central node (Vc), a low voltage clamping switch (25) inserted between said central node (Vc) and a reference voltage (GND), the receiving switch (30) being low voltage and being inserted between the central node (Vc) and the low voltage output terminal (LVout), the clamping switch (25) and the receiving switch (30) being controlled in a complementary way with respect to each other. A transmission channel ( 1) for ultrasound applications is also described comprising at least such a switching circuit (10) and a process for driving said switching circuit (10).
