NS5S1153
USB 2.0 High Speed and
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; headset; the 2 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. This reduces Pop & Click noise in the audio system.
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 is housed in a space saving, ultra low profile 1.4 x
1.8 x 0.5 mm 10 pin UQFN package.
