ISL54400, ISL54401, ISL54402
Low Voltage, Dual SPDT, USB/Audio
Switches with Negative Signal Capability
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 +85°C.
