Manufacturer Part Number
ISL54206
Description
MP3/USB 2.0 High Speed Switch
Manufacturer
Intersil Corporation
Datasheet
MP3/USB 2.0 High Speed Switch with
Negative Signal Handling
The Intersil ISL54206 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 ISL54206 logic control pins are 1.8V compatible which
allows for control via a standard µcontroller. With a VDD
voltage in the range of 2.7V to 3.6V the IN pin voltage can
exceed the VDD rail allowing for the USB 5V VBUS voltage
from a computer to directly drive the IN pin to switch
between the audio and USB signal sources in the portable
device. The part has an audio enable control pin to open all
the switches and put the part in a low power state.
The ISL54206 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.
