Abstract
A semiconductor integrated circuit comprises a first transistor which has one end connected to a first node where a first voltage is output, and which transfers the first voltage to an output terminal, a second transistor which has one end connected to a second node where the second voltage is output, and which transfers the second voltage to the output terminal, a third booster circuit which supplies a third voltage obtained by further boosting the first voltage to a control terminal of the first transistor, and a fourth booster circuit which supplies a fourth voltage obtained by further boosting the second voltage to a control terminal of the second transistor. The third booster circuit lowers a voltage supplied to the control terminal of the first transistor to turn off the first transistor at a time after discharging of the first node is started. The fourth booster circuit increases, in accordance with a signal from the third booster circuit, a voltage supplied to the control terminal of the second transistor to turn on the second transistor after the first transistor is turned off.
