Abstract
An integrated circuit is provided with a terminal that functions to pass a data signal during a high-speed data mode of operation and to pass an audio signal during an audio mode of operation. The integrated circuit includes an audio source that couples to the terminal through an audio pass transistor during the audio mode of operation. To maintain the audio pass transistor off during the high-speed data mode of operation, the integrated circuit includes a first transistor coupled between the terminal and a gate of the audio pass transistor. The first transistor conducts negative charge from the terminal to the gate of the audio pass transistor.
