Specifications of ISL54208EVAL1Z

Main Purpose
Interface, Analog & Digital Switch
Embedded
No
Utilized Ic / Part
ISL54208
Primary Attributes
2 x SPDT Audio, USB & Video Switch
Secondary Attributes
1.8 V ~ 5.5 V Supply
Lead Free Status / RoHS Status
Lead free / RoHS Compliant
Low Voltage, Dual SPDT, USB/CVBS/
Audio Switches, with Negative Signal
Capability
The Intersil ISL54208 dual SPDT (Single Pole/Double
Throw) switches combine low distortion audio/video and
accurate USB 2.0 high speed (480Mbps) data signal
switching in the same low voltage device. When operated
with a 2.7V to 3.6V single supply these analog switches
allow audio/video signal swings below-ground, allowing the
use of a common USB and audio/video connector in digital
cameras, camcorders and other portable battery powered
Personal Media Player devices.
The ISL54208 logic control pins are 1.8V logic compatible
which allows 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/video and USB signal sources in the
portable device. The part has an enable control pin to open
all the switches and put the part in a low power state.
The ISL54208 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.
