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

controller.

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

TQFN

package and a 10 Ld 3mmx3mm TDFN

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

+85°C.

5. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.

6. Parameters with limits are 100% tested at +25°C. Limits across the full temperature range are guaranteed by design and correlation.

7. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
