Feature Description (continued)

8.3.2.1 Pin Leakage

When the voltage on the D- pins rises above VCC + 1 V a leakage path in the device starts conducting as shown

in Figure 14. The amount of leakage depends on the VCC voltage and the pin voltage. This leakage is governed

by Equation 1:

8.4 Device Functional Modes

8.4.1 High Impedance Mode

The TS3USB3000 has a high impedance mode that places all the signal paths in a Hi-Z state while the device is

not in use. To put the device in high impedance mode and disable the switch, the bus-switch enable pin OE must

be supplied with a logic High signal.
