Claim Text:
1. A discharge path circuit providing a discharge path for an input terminal of an IC (Integrated Circuit) having a power input port connected to a first input and an operation mode selection port connected to a second input, the circuit characterized by: an LC filter unit interconnected between the power input port and the first input to filter a noise in power; a first resistor interconnected between the first input and the second input; and a second resistor interconnected between the second input and a ground to provide the discharge path, wherein a first end of the second resistor is connected to the first resistor and a second end of the second resistor is connected to the ground, wherein a DC power charged in the power input port is discharged through the second resistor when the first input is turned off, and wherein a first end of the LC filter unit is connected to a first node coupled to the first input and a second end of the LC filter unit is connected to a second node coupled to the power input port of the IC, and a first end of the first resistor is connected to the first node and a second end of the first resistor is connected to a third node coupled to the second input.
