TMUX136RSER Descripción general
What is an analog switch/multiplexer? An analog switch (also called a multiplexer or MUX) is a solid-state semiconductor device that routes analog or digital signals between multiple input/output paths under digital control, using MOSFET transistors as the switching elements. Analog switches sit within the broader hierarchy of interface ICs -> signal routing -> semiconductor ICs. The 2:1 (SPDT) configuration means each of the two independent channels can connect a common pin to one of two possible inputs, a topology commonly used for signal multiplexing, source selection, and USB/MIPI/LVDS switching.
Key features include a -3 dB bandwidth of 6 GHz, 1.4 pF on-state capacitance (Con), 9.5 ohm typical on-resistance (Ron), and 1.8 V-compatible control inputs that interface directly with low-voltage processor GPIOs. Power-off protection forces all I/O pins into high-impedance mode when VCC is removed, protecting downstream components and preventing back-powering through the signal path. The flow-through pinout places inputs and outputs on opposite sides of the package, simplifying PCB routing.
The architecture uses N-channel MOSFET pass transistors driven by a charge-pump-assisted gate driver, which achieves low Ron flatness across the input signal range and supports bidirectional signal paths. The 6 GHz bandwidth enables pass-through of high-speed differential protocols such as USB 2.0, MIPI DSI/CSI, and LVDS without significant insertion loss.
Typical applications include tablet and notebook signal multiplexing, smartphone MIPI/DSI switching, USB 2.0 high-speed signal routing, and audio signal path selection. The device also finds use in test equipment and instrumentation where high-bandwidth signal multiplexing is required.
When designing with this device, observe the absolute maximum ratings for analog signal voltage. Use controlled-impedance PCB traces (typically 50 ohm single-ended or 90 ohm differential) for high-frequency signals to preserve signal quality at the rated 6 GHz bandwidth.

Aplicaciones típicas
TMUX136RSER es adecuado para 6 aplicacións: Tablet and Notebook USB 2.0 Signal Routing, Smartphone MIPI DSI/CSI-2 Lane Switching, Audio Signal Path Selection, Test and Measurement Equipment Multiplexing, Automotive Infotainment Signal Switching, Industrial Control Signal Multiplexing.
Tablet and Notebook USB 2.0 Signal Routing
The TMUX136RSER is ideal for routing USB 2.0 high-speed signals (480 Mbps) between multiple ports or between a port and a USB controller, leveraging its 6 GHz -3 dB bandwidth and 1.4 pF Con. Placing the switch between the USB connector and the SoC preserves signal integrity across the D+/D- differential pair with minimal insertion loss and inter-symbol jitter. The 2.3 V to 4.8 V VCC range accommodates both 3.3 V and 1.8 V system rails commonly found in tablet and notebook platforms. Power-off protection prevents back-powering when the cable is hot-plugged.

Smartphone MIPI DSI/CSI-2 Lane Switching
In smartphone display and camera modules, the TMUX136RSER switches MIPI DSI/CSI-2 differential lanes between primary and secondary displays or cameras. Its 6 GHz bandwidth preserves the high-speed data rates of MIPI D-PHY up to 2.5 Gbps per lane, while the 9.5 ohm typical on-resistance minimizes signal attenuation. The compact UQFN-10 (2.0 x 1.5 mm) footprint fits in space-constrained mobile PCB layouts. Power-off protection is critical when the display or camera is disconnected, preventing fault currents through the SoC pins.
Recomendado
Audio Signal Path Selection
The TMUX136RSER can route analog audio signals between multiple sources (Bluetooth receiver, line input, microphone) and the audio codec input, thanks to its low Ron of 9.5 ohm and bidirectional signal support. While audio signals do not require the 6 GHz bandwidth, the device's low on-state capacitance preserves high-frequency treble content in the audio path. The 1.8 V compatible control inputs allow direct GPIO control from low-voltage audio processors without level shifters.
Recomendado
Test and Measurement Equipment Multiplexing
In automated test equipment (ATE) and bench instruments, the TMUX136RSER routes high-frequency test signals between the device under test (DUT) and measurement instruments such as oscilloscopes or spectrum analyzers. The 6 GHz -3 dB bandwidth supports RF and microwave signal switching up to 6 GHz with minimal insertion loss. The two independent SPDT channels enable simultaneous routing of differential signals (e.g., for vector network analyzer measurements). Power-off isolation protects sensitive instrumentation from fault voltages when the MUX is unpowered.
Recomendado
Automotive Infotainment Signal Switching
The TMUX136RSER can be deployed in automotive infotainment systems to switch LVDS display signals, USB data lines, or camera video streams between head units and rear-seat entertainment modules. Its wide operating temperature range of -40 C to +85 C supports the automotive environment. The power-off protection feature is particularly valuable in automotive applications where battery disconnection events must not damage downstream components. For full AEC-Q100 qualification, designers should consult TI for the automotive-grade variant.
Recomendado
Industrial Control Signal Multiplexing
In industrial PLC and process control systems, the TMUX136RSER multiplexes sensor signals or communication bus lines (RS-485, RS-232) between multiple sources and a single controller input. The 6 GHz bandwidth is overkill for these low-speed signals but provides excellent headroom and signal integrity. The wide 2.3 V to 4.8 V VCC range accommodates common industrial 3.3 V and 5 V supply rails. The compact UQFN-10 package enables high-density PCB layouts typical of multi-channel industrial IO modules.

Notas de diseño
Use controlled-impedance PCB traces (50 ohm single-ended or 90 ohm differential) for all signal paths to and from the TMUX136RSER. At 6 GHz bandwidth, impedance mismatches cause reflections that degrade signal integrity. Keep trace lengths as short as possible, and maintain continuous reference planes beneath signal traces. Add ground vias adjacent to signal vias to minimize parasitic inductance at transitions.
The TMUX136RSER on-state capacitance of 1.4 pF forms a low-pass filter with the source and load impedances. For 90 ohm differential USB 2.0 high-speed signals, the -3 dB corner frequency of this RC network is approximately f3dB = 1 / (2*pi*R*C) = 1.26 GHz, well above the 480 Mbps USB signal fundamental. This ensures minimal insertion loss at USB 2.0 data rates.
Place a 0.1 uF decoupling capacitor as close as possible to the VCC pin (pin 5) of the TMUX136RSER, with a short, wide trace to ground. This suppresses power supply noise that could couple into the signal path via the substrate. For systems with high-frequency noise on the supply rail, add a 10 uF bulk capacitor in parallel. Ensure the ground connection uses a low-impedance via to the ground plane.
Do not exceed the absolute maximum analog signal voltage rating specified in the datasheet. Signals exceeding this limit can forward-bias the ESD protection diodes and inject current into the VCC rail. Also verify that the TMUX136RSER select inputs (S1, S2) are driven by GPIO pins capable of sourcing the required logic-high current - some low-power GPIO pins may not meet the input drive specification.
