ISL54214
USB 2.0 High-Speed x 2 Channels/Stereo Audio Dual SP3T (Dual 3 to 1 Multiplexer)
FN6816 Rev 3.00 June 28, 2010
The Intersil ISL54214 is a single supply dual SP3T analog switch that operates from a single supply in the range of 2.7V to 4.6V. It was designed to multiplex between audio stereo signals and two different USB 2.0 high speed differential data signals. The audio channels allow signal swings below ground, allowing the multiplexing of the voice and data signals through a common headphone connector in Personal Media Players and other portable battery powered devices.
The audio switch cells can pass ±1V ground referenced audio signals with very low distortion (<0.03% THD+N when driving 5mW into 32Ω loads).
