NCN1154
DP3T USB 2.0 High Speed /
Audio Switch with Negative
Swing 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 USB data or audio signals
from an external headset. The switch is capable of passing signals with
negative voltages as low as 2 V below ground.
The NCN1154 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.
This reduces Pop & Click noise in the audio system. The device has an
extended V_CC range which can operate off V_CC up to 4.2 V while
passing true ground audio signals down to −2 V.
