The Intersil ISL54212 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 2.5V to 5.5V 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 ISL54212 logic control pins are 1.8V compatible which allows for control via a standard µcontroller. The part has an audio enable control pin to open all the switches and put the part in a low power state.
The ISL54212 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.
