Abstract
The present invention is aimed at providing an output circuit that is of relatively small scale and may perform adjustment to make the output-signal rise slew rate and the fall slew rate equal to each other. An output circuit includes a signal output unit configured to produce at a signal output node a signal that makes transition between a first potential and a second potential, a load circuit having a variable load, and a first switch circuit configured to select one of electrical conduction and non-conduction between the signal output node and the load circuit.
