The ISL54409EVAL1Z and ISL54410EVAL1Z evaluation boards are designed to provide a quick and easy method for evaluating the ISL54409 and ISL54410 audio/USB wired-OR switches. The ISL54409 or ISL54410 µTQFN IC is soldered onto its evaluation board and designated as U1.

The ISL54409 and ISL54410 are dual SPST audio switches with low OFF capacitance on the output terminals. This allows USB 2.0 HS signals to be connected to the output terminals with minimal degradation of the USB signal in a wired-OR configuration for 2:1 multiplexing of audio and USB 2.0 signals to a common connector.

The ISL54409 features a low power shut down mode while the ISL54410 features integrated audio click and pop elimination.
