PI3A6386 includes a dual, single-pole double throw (SPDT) switch for high-speed USB signal and high quality audio signal. It can be used in USB Type-C D+/D- switching for USB signal in data mode and analog audio signal in audio accessory mode.

The audio path with negative signal handling capability has a very low THD of -110dB for high-quality audio requirement. It also has a programmable soft-start/soft-stop feature to eliminate the click/pop sounds of DC-coupled audio signals. The data path has a high USB bandwidth of 1GHZ for USH High Speed signals.

PI3A6386 can also detect the microphone signals in SBU1 and SBU2, and automaticlaly route them to the correct inputs of microphone amplifier. Separate switches for microphone negative input and audio signal ground can minimize the crosstalk & echo between audio output signals and microphone input signals. Sideband switches can be configured to route SBU1 and SBU2 for sideband usage.
