Low Voltage, Dual SPDT, USB/Audio
Features
• Low Distortion Negative Signal Capability
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.

• 1.8V Logic Compatible (ISL54402)
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
voltage, which is used to switch

Audio Switches
Detailed Description
The two NC (normally closed) audio switches (L, R, NCx)
are 1Ω switches that can pass signals that swing below
ground. Crosstalk between the audio switches is < -110dB
and has a -3dB bandwidth of 394MHz.
The ISL5440X family of devices are dual single pole/double
throw (SPDT) analog switches that operate from a single
power supply. They were designed to function as dual 2 to 1
multiplexers to select between USB differential data signals
and audio L and R stereo signals. They come in tiny µTQFN
package for use in MP3 players, PDAs, cellphones, and
other personal media players.
The recommended maximum signal range is from -1.5V to
1.5V. You can apply positive signals greater than 1.5V but
the R
resistance of the switch increases rapidly above
ON
1.5V. The audio signal should not be allowed to exceed the
rail or swing more negative than -1.5V.
All devices in this family consist of two 1Ω normally closed
(NC) audio switches and two 5Ω normally open (NO) USB
switches. The audio switches can accept signals that swing
below ground. They were designed to pass audio left and
right stereo signals, that are ground referenced, with minimal
distortion. The USB switches were designed to pass full-
speed USB differential data signals with minimal edge and
phase distortion.

Over a signal range of ±1V these switches have an
extremely low R flatness. They can pass ground

referenced audio signals with very low distortion (<0.01%
THD+N) when delivering 12mW into a 32Ω headphone
speaker load. See Figures 8 and 9 THD+N performance
curves.
The ISL54400 and ISL54401 were specifically designed for
MP3 players, personal media players and cellphone
applications that need to combine the audio headphone jack
and the USB data connector into a single shared connector,
thereby saving space and component cost. A typical
application block diagram of this functionality is shown
above. The ISL54400 and ISL54401 incorporate circuitry for
These switches are uni-directional switches. The audio
sources should be connected at the NC side of the switch
(pins 7 and 8) and the speaker loads should be connected at
the COM side of the switch (pins 3 and 4).

The ISL54402 is an audio/data switch and its functionality is
typical of a standard dual SPDT device.
For the ISL54402 part the NC1 audio switch is active (turned
ON) whenever logic pin IN1 (pin 10) is LOW. The NC2 audio
switch is active (turned ON) whenever the logic pin IN2
(pin 2) is LOW. Unlike the ISL54400 and ISL54401 parts
A detailed description of the two types of switches and of
each part type in the ISL5440x family are provided in the

USB Switches
The two NO (normally open) USB switches (D+, D-, NOx)
are 5Ω bidirectional switches that are designed to pass low
speed and full-speed USB differential signals typically in the
range of 0V to 3.6V. The switches have low capacitance and
high bandwidth to pass USB full-speed signals (12Mbps)
