ABSTRACT:
An integrated circuit device is provided which can increase a stable area having less digital noise. A data delay adjustment circuit group (110) is fed with data outputted from a flip-flop circuit group (106), adjusts a delay of the data so as to synchronize the operation of a data output terminal group (114) with the operation of a logic circuit (100), and outputs the data to the data output terminal group (114). A clock delay adjustment circuit (109) similarly adjusts a delay of a clock outputted from an inverter (105) and outputs the clock to a clock output terminal (113). Therefore, the operations of data output terminals are synchronized with the operation of the logic circuit (100) while keeping the phase relationship between an external output clock and external output data.
