NS5S1153 USB 2.0 High Speed and Audio Switch with Negative Swing Capability The NS5S1153 is a DPDT switch for combined trueground audio and USB 2.0 high speed data applications. It allows portable systems wwwwww..onsemi.comonsemi.com 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. MARKING The switch is capable of passing signals with negative voltages as DIAGRAMS 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 UQFN10 AJM off and provide a safe path to ground for any charge that may build up CASE 488AT on the audio lines. This reduces Pop & Click noise in the audio system. 1 The NS5S1153 is also equipped with VBUS detection circuitry to AJ = Specific Device Code immediately switch to USB mode in the event that a voltage is M = Date Code detected on VBUS. = PbFree Package The NS5S1153 is housed in a space saving, ultra low profile 1.4 x (Note: Microdot may be in either location) 1.8 x 0.5 mm 10 pin UQFN package.
