Audio/USB 2.0 Wired-OR Switch with Click and
Pop Reduction
ISL54409, ISL54410
The Intersil ISL54409 and ISL54410 are Dual SPST
(Single Pole/Single Throw) switches that provides a
very low distortion audio path for a stereo headphone
and can be connected in a wired-OR configuration at the
switch outputs with USB2.0 HS signals for Audio/USB
signal multiplexing to a common connector. The audio
switch path can be disabled to provide high signal
isolation, preventing crosstalk between the audio codec
and USB data signals.
The ISL54409 and ISL54410 analog switches are
negative swing capable with a single supply voltage and
maintain excellent THD performance within a signal
range of -1V to +1V. The switch terminals have low pin
capacitance (4pF typical), minimizing impact to USB 2.0
High-Speed signals. The ISL54409 offers a Low Power
Shutdown mode while the ISL54410 offers a High
Off-Isolation mode. The ISL54410 contains active Audio
Click and Pop Elimination circuitry for AC-coupled audio
signals.
The ISL54409 and ISL54410 are available in a 8 Ld
TDFN (2mmx2mm) or a 10 Ld µTQFN (1.8mmx1.4mm)
package. They operate over a temperature range of
-40 to +85°C.

CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact
product reliability and result in failures not covered by warranty.
NOTES:
6. Signals on LIN, RIN, COM-, COM+, IN and CTRL exceeding VDD or GND by specified amount are clamped. Limit current to
maximum current ratings.
7. θJA is measured in free air with the component mounted on a high effective thermal conductivity test board with “direct attach”
features. See Tech Brief TB379.
8. For θJC, the “case temp” location is the center of the exposed metal pad on the package underside.
Electrical Specifications - 2.7V to 3.6V Supply Test Conditions: VDD = +3.0V, GND = 0V, VCTRL = 1.4V, VIN = 0.5V,
(Notes 9, 10), Unless Otherwise Specified. Boldface limits apply over
the operating temperature range, -40°C to +85°C.
