An output driver of a semiconductor integrated circuit having low power consumption and reduced layout area transmits internally generated data of the circuit to pads responsive to clock signals, and is controlled by control signals indicative of changes of process, voltage, and temperature. The output driver includes a data selector, an output driver enabler, a first driver that transmits an output of the output driver enabler to the pads, and a second driver that includes a data delay having a plurality of inverters connected in series to an output of the output driver enabler and being activated responsive to the control signals. The second driver transmits an output of the data delay to the pads. The output driver reduces a load on the clock signal line, so that power consumption and a layout area can be reduced.
