An integrated circuit includes an input terminal configured to receive an input signal, a reference voltage node configured to provide a control voltage, and a pass transistor comprising a first terminal coupled to a first node, a control terminal coupled to the reference voltage node, and a second terminal coupled to the input terminal. The control voltage has a control voltage level sufficient to allow a signal to pass from the second terminal to the first terminal. The pass transistor is configured to linearly transfer the input signal to the first node in response to a voltage level of the input signal being below a first voltage level and configured to transfer a voltage-limited version of the input signal to the first node in response to the voltage level being above the first voltage level. At most, a negligible DC current flows through the input terminal into the second terminal.
