Abstract
An output circuit outputs communication signals and communicates with an external device ED, and includes: a PNP first transistor, which is capable of outputting a collector current as the communication signals; and a first current source, which is capable of changing a base current of the first transistor, and which reduces the base current to a predetermined current value after the first transistor is turned on and before the first transistor is turned off.
