ISL54215 MP3/USB 2.0 High Speed Switch with Negative Signal Handling and Low Power Shutdown

The Intersil ISL54215 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 for the use of a common USB and audio headphone connector in Personal Media Players and other portable battery powered devices.

The ISL54215 logic control pins are 1.8V compatible, which allows for control via a standard microcontroller.

The ISL54215 has an audio enable control pin to open all switches and put the part in a low power state. In this state, the device draws typically 1nA of current.

The ISL54215 is available in a small 10 Ld 2.1mmx1.6mm ultra-thin μTQFN package. It operates over a temperature range of -40°C to +85°C.
