<p>PURPOSE:To prevent that logical inversion of a digital signal propagates as noise to an analog circuit, and causes malfunction to the analog circuit, in a semiconductor integrated circuit containing digital circuits and analog circuits. CONSTITUTION:A lead pin 105 is arranged between a lead pin 104 dealing with a digital signal and a lead pin 106 dealing with an analog signal, which lead pin 105 is connected with a fixed potential or terminated with the fixed potential. Hence the lead pin 104 and the lead pin 105 are arranged. Thereby the capacitance between the lead pin 104 and the lead pin 106 is isolated, and it is prevented that the logical inversion of the digital signal propagates as noise to the analog circuit and causes malfunction to the analog circuit.</p> |
