The NL3S22S is a double−pole/double−throw (DPDT) analogswitch for routing high speed differential data and audio. Thehigh−speed data path is compliant with High Speed USB 2.0, FullSpeed USB 1.1, Low Speed USB 1.0 and any generic UART protocol.The multi−purpose audio path is capable of passing signals withnegative voltages as low as 2 V below ground and features shuntresistors to reduce Pop and Click noise in the audio system.
