ISL54205B
MP3/USB 2.0 High Speed Switch with
Negative Signal Handling
The Intersil ISL54205B 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 ISL54205B 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 ISL54205B is available in a small 10 Ld 2.1mmx1.6mm
ultra-thin TQFN package and a 10Ld 3mmx3mm TDFN
package. It operates over a temperature range of -40 to
+85°C.
