    摘要： A semiconductor integrated circuit includes low voltage peration circuitries (I) such as I 2 L and high voltage opera- ion circuitries (Q) operating at a higher voltage than the low oltage operation circuitries. Both of the low and high oltage operation circuitries (I, Q) are implemented in a single semiconductor chip in coexistence with each other. The low voltage operation circuitries are disposed in con- ;tant current paths in the high voltage operation circuitries so that the currents once used by the high voltage operation circuits are utilized again by the low voltage operation circuitries. Power dissipation of the whole integrated circuit s thus reduced significantly.
