Abstract
In a bus driver for driving a bus having first and second power supply terminals, an input terminal for receiving an input signal and an output terminal connected to the bus, a switching element is provided between the output terminal and the second power supply terminal, and the switching element is controlled by a voltage at the input terminal. A pull-up resistor is connected between the first power supply terminal and the output terminal.
