MP3/USB 2.0 High Speed Switch with Negative
Signal Handling and Low Power Shutdown
ISL54209
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 for 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 µcontroller.
The ISL54209 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 ISL54209 is available in a small 10 Ld 1.8mm x
1.4mm or 2.1mmx 1.6mm ultra-thin µTQFN packages
and a 10 Ld 3mmx3mm TDFN package. It operates over
a temperature range of -40°C to +85°C.
