FN6403.0
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
V_BUS 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.
