9.2.1 Design Requirements

Design requirements of USB 1.0,1.1, and 2.0 standards must be followed. The TS5USBC400 has internal 6-MΩ pulldown resistors on SEL1, SEL2, and OE, so no external resistors are required on the logic pins. The internal pull-down resistor on SEL1 and SEL2 pins ensures the D1+ and D1- channels are selected by default. The internal pull-down resistor on OE enables the switch when power is applied to VCC.
