ABSTRACT:
An input circuit having a plurality of channels, each channel includes a conductor line, first and second transistors inserted in series into the conductor line and a third transistor.
When a channel is not selected, the first and second transistors are turned off and the third transistor is turned on to clamp the conductor line at a predetermined constant voltage. When a channel is selected, the third transistor is turned off and first and second transistors are turned on to transfer the corresponding information input therethrough.
