The Supertex The analog switch terminals are Tx and Rx. Rx has integrated clamping diodes to RGND to protect the receiver against high voltages. Voltages greater than ±0.6V will start forward biasing the clamp diodes to RGND. The MD0101 can be considered as a normally closed switch with a typical switch resistance of 15Ω, allowing small signals to pass. Once the voltage drop across the switch exceeds a nominal value of ±1.0V, the device will start to turn off. In the off state, the MD0101 can withstand up to ±100V across its terminals. A small amount of current, 200µA, is allowed to flow through. The MD0101 is not limited to just ultrasound applications.
