Detailed Description
The ISL54209 device is a dual single pole/double throw
(SPDT) analog switch that operates from a single DC power
supply in the range of 2.5V to 5.0V. It was designed to
function as a dual 2 to 1 multiplexer to select between USB
differential data signals and audio L and R stereo signals. It
comes in tiny μTQFN and TDFN packages for use in MP3
players, PDAs, cellular phones and other personal media
players.
The part consists of two 2.5
Ω
audio switches and two 5
Ω
USB switches. The audio switches can accept signals that
swing below ground. They were designed to pass audio left
and right stereo signals, that are ground referenced, with
minimal distortion. The USB switches were designed to pass
high-speed USB differential data signals with minimal edge
and phase distortion.
The ISL54209 was specifically designed for MP3 players,
personal media players and cellular phone applications that
need to combine the audio headphone jack and the USB
