Product details
Overview
MAX4736ELB+T from Maxim Integrated is a low-voltage, dual SPDT analog switch operating from a single 1.6V to 4.2V supply, featuring 0.6Ω on-resistance (at 3V), 25ns turn-on time, and break-before-make switching. It supports rail-to-rail analog signal routing in battery-powered audio/video systems and low-voltage data-acquisition circuits.
For engineers reviewing the MAX4736ELB+T datasheet, MAX4736ELB+T pinout, MAX4736ELB+T application, or MAX4736ELB+T equivalent, this device is selected for ultra-low RON, sub-30ns switching speed, 1.8V CMOS logic compatibility at 3V supply, and µDFN (2mm × 2mm) packaging optimized for space-constrained portable designs.
Technical Context
The MAX4736ELB+T implements two independent SPDT switches using CMOS architecture, each with one normally open (NO) and one normally closed (NC) path controlled by separate digital inputs (IN1/IN2). Its break-before-make timing prevents signal shorting during state transitions.
It operates bidirectionally across the full analog range (GND to V+), maintains 0.1Ω RON matching and 0.05Ω RON flatness at 3V, and draws only 1µA supply current - enabling use in always-on, low-quiescent-power signal routing paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 4.2V single supply - enables direct integration with Li-ion battery (3.0–3.7V) and 1.8V/3.3V logic domains. |
| On-Resistance (RON) | 0.6Ω typical at 3V - minimizes voltage drop and power loss in high-current analog paths (±300mA continuous). |
| RON Matching | 0.1Ω max between channels - ensures matched gain/attenuation in differential or dual-path signal routing. |
| Switching Speed (tON/tOFF) | 25ns / 20ns max - supports high-speed multiplexing in audio, video, and serial interface signal paths. |
| Logic Compatibility | 1.8V CMOS input thresholds at 3V supply - allows direct interfacing with 1.8V microcontrollers without level shifters. |
| Off-Isolation | −52dB at 1MHz - suppresses crosstalk between active and inactive signal paths in multi-channel systems. |
| Charge Injection | 60pC - limits glitch amplitude in precision sampling circuits and ADC front-ends. |
Pinout & Package
MAX4736ELB+T is housed in a 10-pin µDFN package (2mm × 2mm) with exposed pad connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO1) | Analog Switch 1 - Normally Open Terminal | Connects to COM1 only when IN1 = high; used for default-open signal routing paths. |
| 2 (GND) | Ground Reference | Primary return path for analog signals and logic; exposed pad must be soldered to PCB ground plane. |
| 3 (NO2) | Analog Switch 2 - Normally Open Terminal | Independent NO path for second SPDT channel; enables dual-path selection without shared control. |
| 4 (IN2) | Digital Control Input - Switch 2 | Active-high logic input controlling NO2/NC2; tolerant up to 3.6V regardless of V+. |
| 5 (IN1) | Digital Control Input - Switch 1 | Independent control for first SPDT; supports asynchronous switching of two signal paths. |
| 6 (COM2) | Analog Switch 2 - Common Terminal | Bidirectional I/O node routed to NO2 or NC2 based on IN2 state; handles ±300mA continuous current. |
| 7 (NC2) | Analog Switch 2 - Normally Closed Terminal | Connected to COM2 when IN2 = low; provides fail-safe or default-closed signal continuity. |
| 8 (V+) | Positive Supply Input | Single power rail for analog and logic sections; bypassing with 0.1µF capacitor to GND is recommended. |
| 9 (NC1) | Analog Switch 1 - Normally Closed Terminal | Default-closed path for Switch 1; complements NO1 to implement true SPDT functionality. |
| 10 (COM1) | Analog Switch 1 - Common Terminal | Main analog I/O for Switch 1; supports rail-to-rail signals (GND to V+) with minimal RON variation. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-Low On-Resistance | 0.6Ω at 3V supply enables <1mV drop at 100mA - critical for precision sensor and audio signal integrity. |
| Break-Before-Make Switching | 5ns guaranteed tBBM prevents momentary shorting between NO and NC paths - essential for fault-tolerant power/audio routing. |
| Rail-to-Rail Analog Operation | Supports signals from GND to V+ without clipping - allows direct connection to ADCs, DACs, and op-amp rails. |
| Sub-1µA Quiescent Current | 0.006µA typical I+ at 3.6V - extends battery life in always-on monitoring and wake-on-event systems. |

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 |
|---|---|---|---|
| TMUX1574RTER | Higher RON (1.5Ω @ 3V), no break-before-make guarantee, 12-pin WQFN (3mm × 3mm) | Targeted at industrial PLC I/O modules requiring higher ESD rating (±4kV HBM), not portable battery systems | Select TMUX1574RTER only if board space allows larger package and system tolerates higher on-loss and undefined switching overlap. |
| ADG732BRUZ | 32-channel single-pole single-throw (SPST), 4Ω RON @ 3V, 16-bit serial interface, TSSOP-48 | Designed for high-channel-count automated test equipment, not dual-path routing with independent control | Choose ADG732BRUZ only when scalable channel count and SPI configuration outweigh need for low RON and SPDT topology. |
Compared with TMUX1574RTER and ADG732BRUZ, the MAX4736ELB+T delivers superior analog performance (0.6Ω RON, 25ns switching, guaranteed break-before-make) in the smallest footprint (2mm × 2mm µDFN), making it optimal for portable, low-power, dual-path signal routing where precision and size are critical.

FAQ
What is the maximum continuous current rating for the MAX4736ELB+T analog switches?
The MAX4736ELB+T supports ±300mA continuous current through its COM_, NO_, and NC_ terminals. This rating applies across the full operating temperature range (−40°C to +85°C) and is validated under worst-case voltage conditions (V+ = 4.2V). Exceeding this limit risks thermal overstress and parametric drift. The MAX4736ELB+T also supports ±500mA peak current (1ms, 10% duty cycle) for transient loads like audio burst signals.
Does the MAX4736ELB+T require external level-shifting when interfaced with a 1.8V microcontroller?
No, the MAX4736ELB+T does not require external level-shifting when used with a 1.8V microcontroller, provided the device is powered from a 3V supply. Its logic inputs (IN1/IN2) are 1.8V CMOS compatible at V+ = 3V, with VIH = 1.4V and VIL = 0.5V. The MAX4736ELB+T also accepts logic high up to 3.6V regardless of V+, allowing direct connection to mixed-voltage systems without added components.
How does the break-before-make timing of the MAX4736ELB+T prevent signal corruption?
The MAX4736ELB+T guarantees a minimum 5ns break-before-make interval (tBBM) between disconnecting one path and connecting the other. This eliminates momentary shorting between NO and NC terminals during switching, preventing signal glitches, DC shorts, or latch-up in sensitive analog paths. In audio routing or power domain isolation, this ensures clean transitions without audible pops or supply disturbances - a key reliability feature confirmed in the MAX4736ELB+T datasheet.
Can the MAX4736ELB+T handle analog signals exceeding the V+ supply rail?
No, the MAX4736ELB+T cannot safely handle analog signals exceeding the V+ supply rail. Its absolute maximum ratings specify COM_, NO_, and NC_ voltages from −0.3V to (V+ + 0.3V). Signals beyond V+ forward-bias internal ESD diodes, risking leakage, distortion, or damage if current exceeds ±300mA. For rail-to-rail operation, analog inputs must stay within GND to V+. The MAX4736ELB+T is designed for true rail-to-rail *within* the supply, not beyond it.
What is the thermal performance of the MAX4736ELB+T in its µDFN package?
The MAX4736ELB+T in the 10-pin µDFN (2mm × 2mm) package has a continuous power dissipation of 423.7mW at TA = +70°C, with a derating factor of 5.3mW/°C above that temperature. Its exposed pad must be soldered to a solid PCB ground plane to achieve this rating. Junction temperature remains below 150°C under typical 100mA load conditions, supporting reliable operation in thermally dense layouts like smartphone camera modules or wearable sensor hubs.
