摘要

A semiconductor integrated circuit comprising a high voltage output driver(1)using high voltage as operation power,and a switching circuit(2)for switching the output state of the high voltage output driver.The high voltage output driver has a series circuit of a first MOS transistor(M1)and a second MOS transistor(M2)having a series contact point as an output terminal in a high voltage current path.When the switching circuit switches complementary switch states of the first MOS transistor and the second MOS transistor,one transistor in ON state is turned to OFF state first,and then,the other transistor is turned to ON state.When this MOS transistor is turned to ON state,no breakdown occurs in the high voltage output driver because the through current path is already disconnected even if Vds exceeds the breakdown minimum voltage.
