Abstract
A transmission circuit includes a first terminal configured so that a first voltage is applied thereto, a second terminal, a third terminal, and a fourth terminal configured so that a second voltage lower than the first voltage is applied thereto. The transmission circuit further includes a first variable resistor portion provided between the first terminal and the second terminal, a first current restriction portion configured to restrict a current flowing from the first terminal to the second terminal, a second variable resistor portion provided between the third terminal and the fourth terminal, a second current restriction portion configured to restrict a current flowing from the third terminal to the fourth terminal, and a control portion configured to control, based on transmission data, the respective resistance values of the first variable resistor portion and the second variable resistor portion.
