The Intersil ISL54207 dual SPDT (Single Pole/Double Throw) switches combine low distortion audio/video and accurate USB 2.0 high speed (480Mbps) data signal switching in the same low voltage device. When operated with a 2.7V to 3.6V single supply, these analog switches allow audio/video signal swings below-ground, allowing the use of a common USB and audio/video connector in digital cameras, camcorders and other portable battery powered Personal Media Player devices.

The ISL54207 incorporates circuitry for detection of the USB VBUS voltage, which is used to switch between the audio/video and USB signal sources in the portable device. The part has a control pin to open all the switches and put the part in a low power down state.

The ISL54207 is available in a small 10 Ld 2.1mmx1.6mm ultra-thin µTQFN package and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40 to +85°C.
