Description

The Intersil ISL54208 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 ISL54208 logic control pins are 1.8V logic compatible which allows control via a standard µcontroller. With a VDD voltage in the range of 2.7V to 3.6V the IN pin voltage can exceed the VDD rail allowing for the USB 5V VBUS voltage from a computer to directly drive the IN pin to switch between the audio/video and USB signal sources in the portable device. The part has an enable control pin to open all the switches and put the part in a low power state.

The ISL54208 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.
