Abstract:
A semiconductor device including a signal transfer line, comprising:a driver having an output node connected to one end of said signal transfer line to set said output node to a first potential in response to a first state of an input signal and to a second potential differing from said first potential in response to a second state of an input signal; and a noise limiter comprising: a first diode element having a first electrode receiving a third potential corresponding to said first potential shifted in level towards said second potential side by a threshold voltage corresponding to said first diode, and a second electrode connected to said signal transfer line, rendered conductive in response to the potential of said signal transfer line exceeding said first potential, and a second diode element having a first electrode receiving a fourth potential corresponding to said second potential shifted in level towards said first potential side by a threshold voltage corresponding to said second diode, and a second electrode connected to said signal transfer line, rendered conductive in response to the potential of said signal transfer line exceeding said second potential.
