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

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

package. It operates over a temperature range of -40 to

+85°C.
