Renesas Electronics Corporation Audio/USB 2.0 Wired-OR Switch with Click and Pop Reduction ISL54410IRTZ-T

The Intersil ISL54409 and ISL54410 are Dual SPST (Single Pole/Single Throw) switches that provide 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.brbr 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.brbr 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°C to +85°C.
