Abstract
In a slew rate adjusting circuit for producing a timing signal determining an output slew rate, a delay circuit for producing an output timing signal is formed of delay circuits with a variable number of delay stages, and the delay time of the output timing signal is adjusted in a step of a delay time of the delay stage in accordance with slew rate adjusting data. A large adjustment margin can be ensured for the output slew rate determining the changing rate of the output data.
