(1) Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Theseare stress ratings
only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended
Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

8 Detailed Description
8.1 Overview
The TS5USBC41 is a bidirectional low-power dual port, high-speed, USB 2.0 analog switch with integrated
protection for USB Type-C systems. The device is configured as a dual 2:1 or 1:2 switch and is optimized for
handling the USB 2.0 D+/- lines in a USB Type-C system as shown in 图 16.
图 16. USB Type-C Connector Pinout
The TS5USBC41 also works in traditional USB systems that need protection from fault conditions such as
automotive and applications that require higher voltage charging. The device maintains excellent signal integrity
through the optimization of both RON and BW while protecting the system with 20 V (TS5USBC410) and 24 V
(TS5USBC412) OVP protection. The OVP implementation is designed to protect sensitive system components
behind the switch that cannot survive a fault condition where VBUS is shorted to the D+ and D- pins on the
connector.

8.3 Feature Description
8.3.1 Powered-off Protection
When the TS5USBC41 is powered off the I/Os of the device remain in a high-Z state. The crosstalk, off-isolation,
and leakage remain within the Electrical Specifications.
This prevents errant voltages from reaching the rest of the system and maintains isolation when the system is
powering up.
8.3.2 Overvoltage Protection
The OVP of the TS5USBC41 is designed to protect the system from D+/- shorts to VBUS at the USB and USB
Type-C connector. 图 17 depicts a moisture short that would cause high voltage (20 V for TS5USBC410 or 20 V
for TS5USBC412) to appear on an existing USB solution that could pass through the device and damage
components behind the device.

9 Application and Implementation
注
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
9.1 Application Information
There are many USB applications in which the USB hubs or controllers have a limited number of USB I/Os or
need to route signals from a single USB connector. The TS5USBC41 solution can effectively expand the limited
USB I/Os by switching between multiple USB buses to interface them to a single USB hub or controller or route
signals from on connector to two different locations. With independent control of the two switches using SEL1
and SEL2, TS5USBC41 can be used to cross switch single ended signals.
9.2 Typical Application
TS5USBC41 USB/UART switch. The TS5USBC41 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 TS5USBC41 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.

9.2.1 Design Requirements
Design requirements of USB 1.0,1.1, and 2.0 standards must be followed. The TS5USBC41 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.
9.2.2 Detailed Design Procedure
The TS5USBC41 can be properly operated without any external components. However, TI recommends that
unused pins must be connected to ground through a 50-Ω resistor to prevent signal reflections back into the
device. TI does recommend a 100-nF bypass capacitor placed close to TS5USBC41 VCC pin.

10 Power Supply Recommendations
Power to the device is supplied through the VCC pin and must follow the USB 1.0, 1.1, and 2.0 standards. TI
recommends placing a 100 nF bypass capacitor as close to the supply pin VCC as possible to help smooth out
lower frequency noise to provide better load regulation across the frequency spectrum.

11 Layout
11.1 Layout Guidelines
1. Place supply bypass capacitors as close to VCC pin as possible and avoid placing the bypass caps near the
D± traces.
2. The high-speed D± must match and be no more than 4 inches long; otherwise, the eye diagram performance
may be degraded. A high-speed USB connection is made through a shielded, twisted pair cable with a
differential characteristic impedance. In layout, the impedance of D+ and D– traces must match the cable
characteristic differential impedance for optimal performance.
3. Route the high-speed USB signals using a minimum of vias and corners which reduces signal reflections and
impedance changes. When a via must be used, increase the clearance size around it to minimize its
capacitance. Each via introduces discontinuities in the signal’s transmission line and increases the chance of
picking up interference from the other layers of the board. Be careful when designing test points on twisted
pair lines; through-hole pins are not recommended.
4. When it becomes necessary to turn 90°, use two 45° turns or an arc instead of making a single 90° turn. This
reduces reflections on the signal traces by minimizing impedance discontinuities.
5. Do not route USB traces under or near crystals, oscillators, clock signal generators, switching regulators,
mounting holes, magnetic devices or ICs that use or duplicate clock signals.
6. Avoid stubs on the high-speed USB signals due to signal reflections. If a stub is unavoidable, then the stub
must be less than 200 mm.
7. Route all high-speed USB signal traces over continuous GND planes, with no interruptions.
8. Avoid crossing over anti-etch, commonly found with plane splits.
9. Due to high frequencies associated with the USB, a printed circuit board with at least four layers is
recommended; two signal layers separated by a ground and power layer as shown in 图 23.
Signal 1
GND Plane
Power Plane
Signal 2
图 23. Four-Layer Board Stack-Up
The majority of signal traces must run on a single layer, preferably Signal 1. Immediately next to this layer must
be the GND plane, which is solid with no cuts. Avoid running signal traces across a split in the ground or power
plane. When running across split planes is unavoidable, sufficient decoupling must be used. Minimizing the
number of signal vias reduces EMI by reducing inductance at high frequencies.
