Abstract
According to one embodiment, a main driver is configured to shift the level of a differential signal. A bypass circuit is configured to bypass current flowing through the main driver in such a manner as to contain the change amount of current running through the main driver flowing from a high power supply potential to a low power supply potential within a fixed range upon transition between an operating state and a standby state of the main driver.
