Abstract
A semiconductor integrated circuit includes an input circuit for receiving an input signal from the outside, an internal circuit connected to the input circuit, an output circuit connected to the internal circuit for outputting an output signal to the outside, a power supply line connected to each of the circuits, a power supply terminal connected to the power supply line, a first ground conductor connected to the input circuit, a second ground conductor separated from the first ground conductor and connected to the internal circuit, a first ground terminal connected to the first ground conductor and a second ground terminal connected to the second ground conductor. Because of the provision of the ground conductor exclusively for the input circuit, malfunction of the input circuit due to power supply fluctuations is prevented and an operation margin is increased.
