Board User's Manual
Overview
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 two 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 V
circuitry to immediately switch to USB mode in the event
that a voltage is detected on V
The NS5S1153 is housed in a space saving, ultra low
profile 1.4 x 1.8 x 0.5 mm 10 pin mQFN package.
