ISL54206A
MP3/USB 2.0 High Speed Switch with Negative
Signal Handling
ISL54206A
The Intersil ISL54206A 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 2.7V to 3.6V 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 ISL54206A logic control pins are 1.8V compatible,
which allows for 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 and USB signal sources in
the portable device. The part has an audio enable control
pin to open all the switches and put the part in a low
power state.
The ISL54206A 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°C to +85°C.
