Description

The Intersil ISL54209 dual SPDT (Single Pole/Double Throw) switch combines low distortion audio and accurate USB 2.0 high speed data (480Mbps) signal switching in the same low voltage device. When operated with a 2.5V to 5.0V single supply, this analog switch allows 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 ISL54209 logic control pins are 1.8V compatible, which allows for control via a standard controller. With a VDD voltage in the range of 2.5V to 3.6V, the IN pin voltage can exceed the VDD rail allowing the USB 5V VBUS voltage from a computer to directly drive the IN pin to switch between the audio and USB signal sources in the portable device. The part has an audio enable control pin to open all the switches and put the part in a low power state. The ISL54209 is available in a small 10 Ld 2.1mmx1.6mm ultra-thin TQFN package and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40C to +85C.
