8 Detailed Description

8.1 Overview

The TS3USB3031 device is a 2-channel, 1:3 multiplexer that includes a high-speed Mobile High-Definition Link (MHL) or Mobility Display Port (MyDP) switch and USB 2.0 High-Speed (480 Mbps) switches in the same package. This device is used in many high-speed differential 1:3 mux applications.

8.3 Feature Description

8.3.1 IOFF Protection

IOFF protection precents current leakage through the device when Vcc = 0 V This allows signals to be present on the D± and USB/MHL± pins before the device is powered up without damaging the device or system.

8.3.2 1.8-V Compatible Logic

The TS3USB3031 device supports 1.8-V logic irrespective to the supply voltage applied to the IC.

8.3.3 Overvoltage Tolerant (OVT)

The D± and USB/MHL± pins of the device can support signals up to 5.5 V without damaging the device. This protects the TS3USB3031 in case the VBUS pin of the USB connector is shorted to the signal path without additional components added.
