Abstract
A circuit apparatus includes an output circuit that outputs a signal to a host apparatus via a bus, and an output control circuit that controls the output circuit. The output circuit has a first conductive transistor provided between an output node and a first power source node, and a second conductive transistor provided between the output node and a second power source node. In a first output mode, the output control circuit controls one of the first conductive transistor and the second conductive transistor to go to off and controls the other transistor to go to on/off, whereas in a second output mode, the output control circuit controls the first conductive transistor to go to on and the second conductive transistor to go to off or vice versa.
