FSA221 - Fairchild Semiconductor

FSA221 USB2.0 High-Speed (480Mbps) and Audio Switches

The FSA221 is a Double-Pole, Double Throw (DPDT) multiplexer that combines a low-distortion audio and a USB2.0 High-Speed (HS) switch path. This configuration enables audio and USB data to share a common connector port. The architecture is designed to allow audio signals to swing below ground. This means a common USB and headphone jack can be used for person.
