Abstract: PURPOSE:To decrease malfunction to be caused by noise generation, and electro-magnetic congestion noise in a semiconductor device system including a wiring substrate by coupling an interval between a drain, which is the output terminal of an MOS transistor to drive an external load, and a control gate by a capacitor. CONSTITUTION:The terminal voltage of a control gate 6 in an N-channel MOS transistor 3 is changed from a low level to a high level and the terminal voltage of an output drain 6 is changed from the high level to the low level in a reverse direction to the control gate voltage. At such a time, feedback in a negative direction is loaded to the control gate voltage in correspondence to the quantity of the change in the terminal voltage of the output drain 6 and the change in the voltage of the control gate 6 is interrupted. Then, the alternative current driving ability of the N-channel MOS transistor 3 is lowered. The larger the output impedance of a control driving block 15 is and the larger a capacitor value is, the more hardly the control gate voltage is changed from the low level to the high level. Thus, the peak value of an output current and a current change rate are decreased and in the semiconductor device system including the wiring substrate, the malfunction caused by the noise generation and the electromagnetic congestion noise can be decreased.
