ISL54207
Low Voltage, Dual SPDT, USB/CVBS/
Audio Switches, with Negative Signal
Capability
The Intersil ISL54207 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 ISL54207 incorporates circuitry for detection of the USB
VBUS voltage, which is used to switch between the
audio/video 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 ISL54207 is available in a small 10 Ld 2.1mm x 1.6mm
ultra-thin μTQFN package and a 10Ld 3mm x 3mm TDFN
package. It operates over a temperature range of -40 to
+85°C.
