Abstract: PURPOSE:To obtain a bus driving circuit operated at a fast speed without the flowing of an excess through-current by lowering the high level more than the level of a conventional power supply by a bus potential so as to decrease the charge/discharge time of the bus. CONSTITUTION:In order to bring the level of the bus to a high level '1' for an active period, an NMOSFETM1 is turned off and an NMOSFETM2 is turned on while the level of a clock phi is '0'. The level of the bus goes to a high level but does not reach a power supply level. Then the TR M1 is turned on by the bus output circuit to bring the level of the bus to '0' when the clock phiis '1' and a write signal, inverse of W is at '0'. A readout circuit gives a data of the bus to the latch when a readout signal, inverse of R is at '0'. Since the high level of the bus at the active state is set lower than the level of the power supply to quicken the discharge speed in such a way, the data is transferred at high speed.
