Abstract
An output circuit includes first and second nodes, a regulator, a pre-driver, and an output driver. The regulator outputs a second voltage to the second node based on a first voltage applied to the first node. The output driver receives a signal from the pre-driver and outputs a second signal. The regulator short-circuits the first and second nodes while the pre-driver is in a standby state, and controls the second voltage to be different from the first voltage after the pre-driver transitions from the standby state to a normal operation state.
