FN6663.0
MP3/USB 2.0 High Speed Switch with
Negative Signal Handling and Mute
Function
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.

NOTES:
8. Vlogic = Input voltage to perform proper function.
9. The algebraic convention, whereby the most negative value is a minimum and the most positive a maximum, is used in this data sheet.
10. Parts are 100% tested at +25°C. Temperature limits established by characterization and are not production tested.
11. Flatness is defined as the difference between maximum and minimum value of on-resistance over the specified analog signal range.
12. Limits established by characterization and are not production tested.
13. rON matching between channels is calculated by subtracting the channel with the highest max rON value from the channel with lowest max rON
value, between L and R or between D+ and D-.
