  Description

The Intersil ISL54205A dual SPDT (Single Pole/Double Throw) switches combine low distortion audio and accurate USB 2.0 high speed data (480Mbps) signal switching in the same low voltage device. When operated with a 2.7V to 3.6V single supply these analog switches allow audio signal swings below-ground, allowing the use of a common USB and audio headphone connector in Personal Media Players and other portable battery powered devices.

The ISL54205A incorporates circuitry for detection of the USB VBUS voltage, which is used to switch between the audio 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 ISL54205A is available in a small 10 Ld 2.1mm x 1.6mm ultra-thin μTQFN package and a 10Ld 3mm x 3mm TDFN package. It operates over a temperature range of -40°C to +85°C.
