Abstract
A noise limiter of a semiconductor integrated circuit device includes a diode-connected N channel MOS transistor between a bus line and a line of a potential lower than the power supply potential by a threshold voltage, and a diode-connected P channel MOS transistor between a line of a potential higher than the ground potential by a threshold voltage and the bus line. The potential of the bus line is limited between the level of the power supply potential and the ground potential, so that the noise level of the bus line is reduced.
