Overview
NCN1154 USB 2.
0 High Speed, UART and Audio Switch with Negative Signal Capability The NCN1154 is a DP3T switch for combined true−ground audio, USB 2.
0 high speed data, and UART applications.
It allows portable systems to use a single port to pass either high speed data or audio signals from an external headset; the 3 channels being compliant to USB 2.
0, USB 1.
1 and USB 1.
0.
The switch is capable of passing signals with negative voltages as low as 2 V below ground.
The device features shunt resistors on the audio ports.
These resistors are switched in when the audio channel is off and provide a safe path to ground for any charge that may build up on the audio lines.
