Product details
Overview
MAX4684EUB+TG104 from Maxim Integrated is a dual SPDT analog switch IC designed for low-voltage signal routing in portable and battery-powered systems. It features 0.5Ω max NC on-resistance and 0.8Ω max NO on-resistance at +2.7V supply, 50ns turn-on time, rail-to-rail analog signal handling, and 1.8V logic-compatible digital inputs. It is used in speaker/headset switching and audio path selection where asymmetrical RON improves load matching.
For engineers reviewing the MAX4684EUB+TG104 datasheet, MAX4684EUB+TG104 pinout, MAX4684EUB+TG104 application, or MAX4684EUB+TG104 equivalent, key selection criteria include NC/NO RON asymmetry, break-before-make timing (2ns), UCSP vs. µMAX package trade-offs, leakage performance (<1nA at +25°C), and 100kHz off-isolation (-64dB).
Technical Context
The MAX4684EUB+TG104 implements two independent SPDT switches with break-before-make action (2ns delay) and fast switching (tON = 50ns, tOFF = 40ns at +3V). Its BiCMOS process enables low RON across 1.8V–5.5V supply range while maintaining rail-to-rail analog signal capability and 1.8V logic compatibility.
It supports bidirectional analog signal flow on COM/NO/NC pins, exhibits RON flatness ≤0.15Ω over full signal range, and achieves -68dB crosstalk at 100kHz - critical for high-fidelity audio routing and multiplexed sensor interfaces where channel interference must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into Li-ion, coin-cell, and 3.3V/5V systems without level-shifting. |
| NC On-Resistance (max) | 0.5Ω at +2.7V - reduces insertion loss and thermal drift in headset ground-path switching. |
| NO On-Resistance (max) | 0.8Ω at +2.7V - provides matched impedance for speaker output paths requiring higher RON tolerance. |
| RON Match (max) | 0.06Ω between channels - ensures balanced gain and phase response in stereo or differential signal routing. |
| Turn-On Time (max) | 50ns at +3V - supports fast audio channel switching without audible pop/click in MP3 players and modems. |
| Off-Isolation | -64dB at 100kHz - suppresses coupling between active and inactive audio/video channels. |
| Supply Current (max) | 50nA at +25°C - extends battery life in always-on headset detection circuits. |
Pinout & Package
MAX4684EUB+TG104 uses the 10-pin µMAX® package (3mm × 3mm), with exposed pad (EP) connected to GND for thermal and EMI performance. Pin numbering follows standard µMAX layout; pin 1 is V+, pin 6 is GND, and EP is electrically tied to GND.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V+ | Positive supply input - must be applied before analog signals to prevent latch-up; absolute max +6V. |
| 2 | NO1 | Channel 1 normally open analog terminal - connects to COM1 when IN1 = high; bidirectional signal path. |
| 3 | COM1 | Channel 1 common analog terminal - serves as input/output node shared between NO1 and NC1. |
| 4 | IN1 | Channel 1 digital control input - 1.8V logic compatible; accepts up to +5.5V regardless of V+. |
| 5 | NC1 | Channel 1 normally closed analog terminal - connects to COM1 when IN1 = low; 0.5Ω max RON. |
| 6 | GND | Ground reference - EP (exposed pad) must be soldered to GND plane for thermal stability and noise reduction. |
| 7 | NC2 | Channel 2 normally closed analog terminal - identical RON spec to NC1; enables dual-path headset/speaker routing. |
| 8 | IN2 | Channel 2 digital control input - independent logic control; supports asynchronous switching of both SPDTs. |
| 9 | COM2 | Channel 2 common analog terminal - isolated from COM1; supports stereo or redundant signal paths. |
| 10 | NO2 | Channel 2 normally open analog terminal - complements NC2; completes second SPDT switch with 0.8Ω max RON. |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetrical RON (NC/NO) | 0.5Ω / 0.8Ω max enables optimized impedance matching for speaker + headset dual-output configurations. |
| Break-before-make timing | 2ns guaranteed delay prevents momentary short-circuit during channel switching in power routing applications. |
| Rail-to-rail analog signal range | Supports full V+ to GND swing without clipping - essential for unbuffered audio and sensor signal chains. |
| Low charge injection (200pC) | Minimizes voltage glitch on COM node during switching - reduces audible pop in headset jack detection. |
| Ultra-low leakage current | <1nA at +25°C ensures minimal DC error in precision multiplexing and battery-monitoring circuits. |
Applications
| Speaker Headset Switching | MP3 Player Audio Routing |
|---|---|
Use Scenario: Automatically route audio output between internal speaker and 3.5mm headset jack based on plug detection. IC Role / Device Role / Timing Role: Dual SPDT analog switch providing isolated NC path to speaker and NO path to headset, controlled by microcontroller GPIO.

Use Scenario: Select between left/right stereo channels, microphone input, or line-in on portable media players with space-constrained PCBs. IC Role / Device Role / Timing Role: Low-RON bidirectional switch enabling flexible analog signal path reconfiguration under firmware control. Use Value: 50ns tON and -68dB crosstalk prevent inter-channel bleed during rapid track changes; 1.8V logic compatibility reduces I/O voltage translation overhead. |
| Cellular Phone Baseband Switching | Battery-Operated Equipment Power Routing |
Use Scenario: Route audio signals between baseband processor, earpiece, loudspeaker, and Bluetooth codec in smartphones. IC Role / Device Role / Timing Role: Dual SPDT switch managing multiple analog audio endpoints with minimal board area and power draw. Use Value: 10-pin µMAX package (3mm × 3mm) saves PCB real estate; 50nA supply current extends standby time in always-listening voice activation circuits. |
Use Scenario: Dynamically enable/disable power to peripheral modules (e.g., GPS, BLE radio) based on system state in IoT sensors and wearables. IC Role / Device Role / Timing Role: Low-RON analog switch acting as solid-state load switch for sub-300mA rails, replacing mechanical relays. Use Value: 0.5Ω RON limits voltage drop to <150mV at 300mA, reducing heat generation; break-before-make prevents supply rail contention during hot-swap events. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4685EUB+ | Symmetric 0.8Ω RON on both NC and NO paths; otherwise identical pinout, timing, and specs. | Better suited for balanced dual-path applications (e.g., stereo line switching) where NC/NO asymmetry is unnecessary. | Select MAX4685EUB+ when equal RON simplifies layout and calibration; MAX4684EUB+TG104 remains optimal for speaker/headset load-matching. |
| TMUX1574RTER | 0.5Ω RON, 1.2V–5.5V supply, 10-pin WQFN, but no guaranteed break-before-make; tON/tOFF ~35ns/25ns. | Lacks specified BBM timing, limiting use in power-routing or relay-replacement where short-circuit prevention is mandatory. | Choose TMUX1574RTER only if faster switching and wider supply range outweigh BBM requirement; MAX4684EUB+TG104 provides deterministic 2ns BBM for safety-critical routing. |
Compared with MAX4685EUB+ and TMUX1574RTER, MAX4684EUB+TG104 uniquely delivers guaranteed 2ns break-before-make timing alongside asymmetrical RON - making it the only option qualified for simultaneous speaker/headset output switching without risk of transient shorts or audio artifacts.

FAQ
What is the maximum supply voltage rating for MAX4684EUB+TG104?
The absolute maximum supply voltage (V+) for MAX4684EUB+TG104 is +6V. Operation beyond this rating risks permanent damage. The device is fully specified from +1.8V to +5.5V, with optimal RON and timing performance at +2.7V to +3.3V. Exceeding +6V violates Absolute Maximum Ratings and may compromise internal ESD protection structures.
Does MAX4684EUB+TG104 support rail-to-rail analog signal operation?
Yes, MAX4684EUB+TG104 supports rail-to-rail analog signal operation - meaning signals from GND to V+ pass through the switch with minimal distortion. This is confirmed in the Electrical Characteristics table (Analog Signal Range: 0 to V+) and Typical Operating Characteristics plots showing RON stability across full VCOM range. No external biasing is required.
Is the MAX4684EUB+TG104 pinout compatible with MAX4685EUB+?
Yes, MAX4684EUB+TG104 and MAX4685EUB+ share identical 10-pin µMAX package pinout, pin functions, and electrical interface. They differ only in internal RON characteristics: MAX4684EUB+TG104 has 0.5Ω NC / 0.8Ω NO, while MAX4685EUB+ has 0.8Ω on both paths. PCB layout and firmware control are interchangeable.
What is the guaranteed break-before-make delay for MAX4684EUB+TG104?
The guaranteed break-before-make (BBM) delay for MAX4684EUB+TG104 is 2ns minimum, as specified in the Electrical Characteristics table under "Break-Before-Make Delay (tBBM)". This ensures no overlap between NC and NO conduction states during logic transitions, preventing momentary shorts in power routing or audio path switching applications.
Can MAX4684EUB+TG104 operate with a 1.8V logic supply while powered from 3.3V?
Yes, MAX4684EUB+TG104 supports 1.8V logic compatibility independently of V+. With V+ = +3.3V, the digital inputs (IN1/IN2) accept VIH ≥ +1.4V and VIL ≤ +0.5V - fully satisfied by 1.8V CMOS logic levels. Input leakage is guaranteed <±1µA, and no level-shifting circuitry is needed, simplifying interface with low-voltage microcontrollers.
