Description

The Intersil ISL54213 dual SPDT (Single Pole/Double Throw) switch combines low distortion audio and accurate USB 2.0 high speed data (480Mbps) signal switching in the same low voltage device. When operated with a 2.5V to 5.0V single supply, this analog switch allows 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 ISL54213 logic control pins are 1.8V compatible, which allows for control via a standard µcontroller.

The part has an audio enable control pin to open all switches and put the part in a mute state. It's high off-isolation (95dB @ 100kHz) provides superior muting of audio signals.

The ISL54213 is available in a small 10 Ld 2.1mmx1.6mm ultra-thin µTQFN package and a 10 Ld 3mmx3mm TDFN package. It operates over a temperature range of -40°C to +85°C.
