Specifications of ISL54401EVAL1Z

Main Purpose
Interface, Analog & Digital Switch
Embedded
No
Utilized Ic / Part
ISL54401
Primary Attributes
2 x SPDT Audio & USB Switch
Secondary Attributes
2.7 V ~ 3.6 V Supply
Lead Free Status / RoHS Status
Lead free / RoHS Compliant
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 V
between the audio and USB signal source in the portable
device. In addition, the ISL54400 includes circuitry for
generation of a V
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
µ
-40 to +85°C.
