Abstract
An output circuit includes a plurality of output drive circuits connected to an output node, and each output drive circuit includes a plurality of output buffers. Each output buffer includes: a first transistor of a first conductivity type and a first resistor provided in series with each other between a first power supply node and the output node; and a second transistor of a second conductivity type provided in series with the first resistor between a second power supply node and the output node. One of the first transistor and the second transistor is activated and the other is deactivated based on a first control signal.
