ABSTRACT:
A semiconductor integrated circuit device has a high-speed bus driver and a bus receiver both connected to a bus line, and the high-speed bus driver enters an active mode powered from a positive power voltage line and a virtual ground line and a sleep mode isolating the virtual ground line from a ground line for reducing power consumption, wherein a switching circuit is connected between the high-speed bus driver and the bus line so as to isolate the bus line from the high-speed bus driver in transition periods and the sleep mode, thereby cutting a conductive path for through-current due to leakage current inherent in the high-speed component field effect transistors of the bus driver.
