Description

The Intersil ISL54400, ISL54401, ISL54402 dual SPDT (Single Pole/Double Throw) switches combine low distortion audio and accurate USB 2.0 full speed data signal switching in the same low voltage device. When operated with a 2.5V 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 ISL54400 and ISL54401 incorporate circuitry for detection of the USB VBUS voltage, which is used to switch between the audio and USB signal source in the portable device. In addition, the ISL54400 includes circuitry for generation of a VTERM voltage of 3.3V for use with USB speed setting pull-up resistor. The ISL54400, ISL54401, ISL54402 are available in 10 Ld 3mm x 3mm TDFN and 10 Ld tiny 2.1mm x 1.6mm ultra-thin TQFN packages. They operate over a temperature range of -40 to +85C.
