Abstract
Provided is a transmitting device for enlarging the size of a data eye of a transmission signal. The transmitting device includes an output driver including a plurality of driver circuits that drive a plurality of multi-level signals onto an output node, and a logic circuit configured to detect a direction of a pull-up or pull-down operation of each of the plurality of driver circuits by transitions of the plurality of driver control signals and generate pulse signals. The plurality of multi-level signals are driven based on a plurality of driver control signals and pulse signals, respectively, and the logic circuit provides a pulse signal to at least one static driver circuit connected to a driver control signal that does not transition, from among the plurality of driver circuits.
