9.2 Typical Application

TS5USBC402 USB/UART switch. The TS5USBC402 is used to switch signals between the USB path, which goes to the baseband or application processor, or the UART path, which goes to debug port. The TS5USBC402 has internal 6-MΩ pull-down resistors on SEL1, SEL2, and OE. The pull-down on SEL1 and SEL2 pins ensure the D1+/D1- channel is selected by default. The pull-down on OE enables the switch when power is applied.
