Abstract
An integrated circuit embedded in a plug of a universal serial bus (USB) 3.1 type-C cable assembly is disclosed. The integrated circuit includes a first pin connected to an operation transmission line through which an operation voltage is transmitted, a second pin connected to a configuration channel (CC) line, a first resistor connected to the first pin, a ground line, and a switching circuit configured to connect the first resistor and the ground line using a channel voltage supplied to the second pin when the operation voltage is not applied, and disconnect the first resistor from the ground line based on the operation voltage.
