Patent number: 10218352Abstract: A semiconductor integrated circuit includes an output circuit driven by a power voltage across a first and a second node. A control circuit is driven by the power voltage to control output a digital signal at a pad terminal, a logic value of the signal being set by a core circuit connected to the output circuit. The digital signal causes a voltage at the first node to be high and a voltage at the second node to low when a predetermined power voltage higher than a withstanding voltage of the output circuit is applied across the first and second nodes. The control circuit controls voltages across terminals of switching elements in the output circuit to be less than their withstanding voltages and to prevent current flowing from the pad terminal to the output circuit when the first power node is in a high impedance state.Type: GrantFiled: August 29, 2016Date of Patent: February 26, 2019Assignee: Kabushiki Kaisha ToshibaInventor: Shohei Fukuda
