Diodes Incorporated PI3A6386 USB Switch
Diodes Incorporated PI3A6386 USB Switch is a dual, Single-Pole Double Throw (SPDT) switch for a high-speed USB signal and high-quality audio signal. This Diodes Incorporated switch can be used in USB Type-C™ D+/D- switching for USB signal in data mode and analog signal in audio accessory mode. The PI3A6386 switch features low distortion, high crosstalk rejection, autonomous microphone switching, and separate ground switches for the microphone and audio to minimize crosstalk and sideband switches. Typical applications include notebooks, PC, cell phones, PDAs, MP3 players, and portable instrumentation.
