Low Voltage, Dual SPDT, USB/Audio

Features

Switches with Negative Signal Capability

• Low Distortion 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.
