Abstract

An integrated circuit has first and second logic circuits having common input terminals and the same complementary logic function. The first logic circuit has a p-type FET circuit block and an n-type FET circuit block each with a high threshold value, while the second logic circuit has a p-type FET circuit block and an n-type FET circuit block each with a low threshold value. An output switch circuit intervenes between the p-type FET and n-type FET circuit blocks in each logic circuit and controls the power supply connection to each logic circuit. In operation, the output of the second logic circuit is connected to the output terminal to realize a low power consumption. In the standby state, the output of the first logic circuit is connected to the output terminal to realize a low leakage current.
