ABSTRACT:
In a system wherein a plurality of semiconductor integrated circuit devices are coexistent and wherein a plurality of supply potential lines are laid, the main power sources of a TTL interface LSI and an ECL interface LSI are shared so as to reduce the number of supply potential lines. Besides, in a case where an LSI, for example, BiCMOS LSI to interface with both the TTL and ECL interface LSI's has a device withstand voltage of about 3 V, it is permitted to interface with both the LSI's across the supply voltage .vertline.5 V.vertline. of the main power source of the TTL interface LSI and the supply voltage .vertline.2 V.vertline. of the power source of the emitter follower portion of the ECL interface LSI because the supply voltages have a difference of 3 V.
