    The Intersil ISL54409 and ISL54410 are Dual SPST (Single Pole/Single Throw) switches that provide a very low distortion audio path for a stereo headphone and can be connected in a wired-OR configuration at the switch outputs with USB2.0 HS signals for Audio/USB signal multiplexing to a common connector. The audio switch path can be disabled to provide high signal isolation, preventing crosstalk between the audio codec and USB data signals.  |
