Data Sheet
MP3/USB 2.0 High Speed Switch with
Negative Signal Handling
The Intersil ISL54205A 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 ISL54205A incorporates circuitry for detection of the USB
V
voltage, which is used to switch between the audio and
BUS
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 ISL54205A is available in a small 10 Ld 2.1mm x 1.6mm
μ
ultra-thin
TQFN package and a 10Ld 3mm x 3mm TDFN
package. It operates over a temperature range of -40 to
+85°C.
