PROBLEM TO BE SOLVED: To provide a semiconductor integrated circuit device in which at least either of signal input/output timing margin of an external pin or voltage margin of an external pin is hard to deteriorate. SOLUTION: An input circuit 5 receiving an external input signal DIN, an input control clock line supplying an input control clock 1 to the input circuit 5, a reference potential line supplying a reference potential Vref to the input circuit 5, an output driver control circuit 10 controlling an output driver 9, and an output control clock line supplying an output control clock 2 to the output driver control circuit 10 are arranged at one side of a pad 4, and an output driver circuit 9 and an output power source line VSSQ supplying a power source to the output driver 9 are arranged at the other side of the pad 4. |
