TS3USBCA4 Multiplexers (Muxes)

Texas Instruments' TS3USBCA4 are passive 4:1 (TS3USBCA420) and 3:1 (TS3USBCA410) muxes that support various types of differential or single-ended signals on the SBU1 and SBU2 terminals of a USB Type-C connector to different interfaces. The signals can be differential DisplayPort auxiliary (AUX), analog audio MIC, and analog ground (AGND), peripheral component interconnect express (PCIe) differential clock, or any other supported generic differential or single-ended signals.

The audio path features ultra-low ON-state resistance (R_ON), low crosstalk, and excellent total harmonic distortion (THD). The break-before-make (BBM) feature prevents signal distortion during signal transfer from one channel to another. The high-speed paths support bandwidth as high as 500 MHz to provide adequate support for DisplayPort AUX, PCIe clock, and other similar signals. These features combined with low power consumption make the TS3USBCA4 suitable for portable audio applications.

The TS3USBCA4 devices offer a wide supply range from 2.4 V to 5.5 V that gives users the flexibility of powering them from a single-cell battery, a 3.3 V regulator, or V_BUS. They also provide options for both commercial and industrial temperature ranges.
