摘要： A semiconductor device permitting the reduction of cost is disclosed. In a semiconductor package wherein electrode pads of a semiconductor chip and corresponding inner leads are electrically coupled with each other through a plurality of bonding wires, sensing wires (second and fourth bonding wires) are made thinner than other bonding wires (first and third bonding wires) coupled to inner leads same as those with the sensing wires coupled thereto, thereby reducing the cost of gold wires to attain the reduction in cost of the semiconductor package.

摘要： In a differential amplifier, when an output node of an output buffer circuit is short-circuited to a high potential supply node, the difference between the potential at an output node of an amplifying circuit and the potential at the output node of the buffer circuit becomes so great as not to be produced in normal operation. A short-circuit protection circuit detects such a state and interrupts or limits a base current supplied to an output transistor of an output pull signal generating circuit, suppressing the flow of excess current into the output node of the buffer circuit.
