FN6556.0

MP3/USB 2.0 High Speed Switch with

Negative Signal Handling

The Intersil ISL54212 dual SPDT (Single Pole/Double

Throw) switches combine low distortion audio and accurate

USB 2.0 high speed data (480Mbps) signal switching in the

same low voltage device. When operated with a 2.5V to 5.5V

single supply these analog switches allow audio signal

swings below-ground, allowing the use of a common USB

and audio headphone connector in Personal Media Players

and other portable battery powered devices.

The ISL54212 logic control pins are 1.8V compatible which

allows for control via a standard 碌controller. The part has an

audio enable control pin to open all the switches and put the

part in a low power state.

The ISL54212 is available in a small 10 Ld 2.1mmx1.6mm

ultra-thin 碌TQFN package and a 10 Ld 3mmx3mm TDFN

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

+85擄C.
