The NS5S1153 is a Double Pole Double Throw (DPDT) USB 2.0 High Speed / Audio Switch with Negative Swing Capability.

The NS5S1153 is a DPDT switch for combined true−ground audio and USB 2.0 high speed data 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 NS5S1153 is also equipped with VBUS detection circuitry to immediately switch to USB mode in the event that a voltage is detected on VBUS. The NS5S1153 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 VCC range which can operate off VCC up to 4.2 V while passing true ground audio signals down to −2 V.

Key Features:

• Low RON Audio /Data DPDT Switch.

• VBUS Detection Circuitry for Automatic Switching Between Audio and USB Modes.
• Audio Channel Shunt Resistors for Pop & Click Noise Reduction.
• Ultra−Low THD in Audio Mode: 0.01% into 16 ohm Load.
• 5.25 V Tolerant Common Pins.
• This is a Pb−Free Device.

Applications:

• Shared USB/Audio Connector.
• Mobile Phones.
• Portable Devices.
