Product details
Overview
TMUX136MRSER from Texas Instruments is a 6-GHz, 2-channel, 2:1 analog switch with power-off isolation, designed for high-speed signal routing in I3C and MIPI interfaces. It features 5.7 Ω typical on-resistance, 1.6 pF typical on-capacitance, 6.1 GHz –3 dB bandwidth, and operates from 2.3 V to 4.8 V supply. Its flow-through UQFN pinout and 1.8-V compatible control inputs enable direct GPIO interfacing in smartphone and notebook applications.
For engineers reviewing the TMUX136MRSER datasheet, TMUX136MRSER pinout, TMUX136MRSER application, or TMUX136MRSER equivalent, key selection criteria include bandwidth preservation at >3 Gbps data rates, sub-10 ps jitter contribution, IOFF protection during power-down, and compatibility with compact PCB layouts requiring minimal board area.
Technical Context
The TMUX136MRSER implements a bidirectional, dual SPDT architecture with independent A and B port paths routed to shared COM1/COM2 outputs. Its charge-pump–assisted switch core maintains low RON flatness (≤1 Ω) across 0–3.45 V I/O swing and supports both single-ended and differential signaling without edge or phase distortion.
Control logic uses active-low EN and level-sensitive SEL pins with internal 6-MΩ pull-downs, enabling default A-port selection and automatic enable-on-power-up behavior. Power-off isolation ensures all I/O pins enter high-impedance state when VCC = 0 V, preventing leakage into unpowered subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (–3 dB) | 6.1 GHz - preserves signal integrity up to 4.5 Gbps data rates with ≤7.6 ps peak-to-peak jitter |
| RON (typical) | 5.7 Ω - minimizes insertion loss and voltage drop for analog/digital signals |
| CON (typical) | 1.6 pF - reduces capacitive loading on high-speed buses like I3C and MIPI D-PHY |
| VCC Range | 2.3 V to 4.8 V - supports operation across battery-backed and regulated rail systems |
| IOFF Protection | Active at VCC = 0 V - prevents current leakage between powered/unpowered domains |
| Control Voltage Compatibility | 1.8-V logic - enables direct interface with low-voltage processor GPIO without level shifters |
| ESD Rating (HBM) | ±5 kV - meets Class II robustness for handheld and portable equipment handling |
Pinout & Package
TMUX136MRSER is housed in a 10-pin UQFN package (RSE), measuring 1.5 mm × 2.0 mm with 0.5-mm pitch. The flow-through layout places inputs (A1, A2, B1, B2) on one side and outputs (COM1, COM2) on the opposite side, simplifying high-speed trace routing and minimizing stub length.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 | I/O signal path A1 | First input/output channel of A port; bidirectional, connects to COM1 or COM2 based on SEL |
| A2 | I/O signal path A2 | Second input/output channel of A port; bidirectional, pairs with A1 for differential or parallel use |
| B1 | I/O signal path B1 | First input/output channel of B port; bidirectional, alternate source for COM1/COM2 |
| B2 | I/O signal path B2 | Second input/output channel of B port; bidirectional, supports dual-lane switching |
| GND | Ground reference | Primary return path for analog and digital currents; must connect to solid ground plane |
| EN | Enable (active low) | Asserting low enables switching; high forces all ports into high-impedance state |
| COM2 | Common output 2 | Shared output node for second signal lane; connected to A2/B2 per SEL state |
| COM1 | Common output 1 | Shared output node for first signal lane; connected to A1/B1 per SEL state |
| SEL | Switch select | Logic low routes COMx to A port; logic high routes COMx to B port |
| VCC | Supply voltage | Power rail for internal charge pump and logic; requires local 0.1-µF bypass capacitor |
Key Features
| Feature | Design Value |
|---|---|
| Power-off isolation | IOFF ≤ ±10 µA at VCC = 0 V - eliminates back-powering risk in multi-rail systems |
| Flow-through pinout | Inputs and outputs on opposite sides - enables straight-through routing, reducing vias and impedance discontinuities |
| I3C protocol support | Validated for 12.5 MHz I3C bus with <2 pF capacitance and full voltage range (1.0–3.3 V) |
| Low power mode | ICC = 5 µA in high-Z state - extends battery life in always-on portable devices |
| Thermal performance | RθJA = 191.6 °C/W - supports operation up to +125°C ambient in thermally constrained spaces |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TMUX1574RTER | 4-channel, 2:1 switch; higher RON (7.5 Ω typ), lower bandwidth (3.5 GHz), same UQFN-16 package | Supports quad-lane routing (e.g., MIPI DSI/CSI-2 x4); not suitable for ultra-high-speed single-lane I3C | Select when expanding to four independent channels; avoid if bandwidth >4 GHz or footprint <2 mm × 1.5 mm required |
| ADG732BRUZ-REEL7 | 32-channel, 1:1 mux; 4.5 Ω RON, 200 MHz bandwidth, TSSOP-48 package | Designed for low-frequency analog multiplexing (e.g., sensor arrays), not high-speed digital protocols | Choose only for DC/low-frequency signal routing; unsuitable for I3C, MIPI, or >100 Mbps digital switching |
Compared with TMUX1574RTER and ADG732BRUZ-REEL7, TMUX136MRSER uniquely balances ultra-high bandwidth (6.1 GHz), ultra-compact footprint (1.5 mm × 2 mm), and I3C-specific validation-making it optimal for next-generation mobile and embedded high-speed interconnects where size and signal fidelity are co-constrained.

FAQ
What is the maximum data rate supported by TMUX136MRSER without violating signal integrity?
TMUX136MRSER supports clean signal transmission up to 4.5 Gbps, contributing only 7.6 ps of peak-to-peak jitter at that rate. Its 6.1 GHz –3 dB bandwidth and <2 pF on/off capacitance ensure minimal eye closure and timing margin erosion in I3C and MIPI applications-validated via measured eye diagrams and TIE histograms in the official datasheet.
Does TMUX136MRSER require external pull-up or pull-down resistors on SEL and EN pins?
No. TMUX136MRSER integrates internal 6-MΩ pull-down resistors on both SEL and EN pins. This allows default A-port selection and automatic enable-on-power-up behavior without external components-reducing BOM count and PCB area while ensuring deterministic startup states.
How does TMUX136MRSER achieve power-off isolation, and what is its leakage current specification?
TMUX136MRSER achieves power-off isolation by forcing all I/O pins into high-impedance state when VCC = 0 V. Per datasheet Section 6.5, IOFF (power-off leakage) is specified at ±10 µA max at TA = –40°C to +125°C-ensuring no current flows between powered and unpowered subsystems during hot-swap or partial power-down scenarios.
Can TMUX136MRSER be used in differential signal paths such as MIPI D-PHY or USB 2.0?
Yes. TMUX136MRSER is explicitly characterized for both single-ended and differential signals. Its matched RON (ΔRON ≤ 0.1 Ω), low crosstalk (–37 dB), and symmetric flow-through pinout preserve differential pair skew and common-mode rejection-making it suitable for MIPI D-PHY, USB 2.0, and other high-speed differential standards.
What is the thermal resistance and maximum operating temperature of TMUX136MRSER?
TMUX136MRSER has a junction-to-ambient thermal resistance (RθJA) of 191.6 °C/W in its UQFN-10 (RSE) package and is fully characterized from –40°C to +125°C. This enables reliable operation in thermally dense environments such as stacked mobile modules or fanless industrial controllers without derating.
