Product details
Overview
MAX4736EUB+T from Maxim Integrated is a low-voltage, dual single-pole/double-throw (SPDT) analog switch operating from a single 1.6V to 4.2V supply. It delivers 0.6Ω on-resistance at 3V, 25ns turn-on time, break-before-make switching, and 1.8V CMOS logic compatibility-enabling precision signal routing in space-constrained battery-powered audio and data-acquisition systems.
For engineers reviewing the MAX4736EUB+T datasheet, MAX4736EUB+T pinout, MAX4736EUB+T application, or MAX4736EUB+T equivalent, key selection criteria include rail-to-rail analog signal handling, sub-1Ω RON matching (0.1Ω), ultra-low quiescent power (<4μW), and μMAX package compatibility with high-density PCB layouts.
Technical Context
The MAX4736EUB+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 (5ns typical) prevents momentary shorting during state transitions, critical for power routing integrity.
Each switch supports bidirectional rail-to-rail analog signals (0V to V+), with leakage currents below ±10nA over temperature and charge injection of only 60pC at 3V-ensuring minimal signal corruption in precision measurement paths and low-distortion audio channels.
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 rails (2.7–4.2V) and 1.8V/3.3V logic domains. |
| On-Resistance (RON) | 0.6Ω max at 3V supply-minimizes voltage drop and power loss in high-current analog paths up to ±300mA continuous. |
| RON Matching | 0.1Ω max between channels-ensures matched gain/attenuation in differential or dual-path signal routing applications. |
| Switching Speeds | tON = 25ns, tOFF = 20ns max-supports high-speed multiplexing in data acquisition and communications circuits up to 130MHz bandwidth. |
| Logic Compatibility | 1.8V CMOS input thresholds (VIH = 1.4V, VIL = 0.5V) 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 audio/video routing. |
| Charge Injection | 60pC-limits voltage glitch on sampled nodes, preserving accuracy in ADC front-end and sample-hold circuits. |
Pinout & Package
MAX4736EUB+T is housed in a 10-pin μMAX package (3mm × 3mm, 0.8mm height) with exposed pad connected to GND for thermal and noise performance. Pin 1 is IN1; pins 2 and 4 are NO1 and NO2; pins 9 and 7 are NC1 and NC2; pins 10 and 6 are COM1 and COM2; pin 3 is GND; pin 8 is V+; pin 5 is IN2; pins not assigned are no-connect.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | Active-high logic inputs controlling Switch 1 and Switch 2 independently; compatible with 1.8V CMOS levels at 3V supply. |
| COM1, COM2 | Common analog terminals | Bidirectional signal ports-connect to source or load; support rail-to-rail analog signals (0V to V+). |
| NO1, NO2 | Normally open analog terminals | Open-circuit when IN_ = low; connect to COM_ when IN_ = high-used for default-off signal paths. |
| NC1, NC2 | Normally closed analog terminals | Shorted to COM_ when IN_ = low; disconnect when IN_ = high-enables default-on or fail-safe routing. |
| GND | Ground reference | Primary return path for analog and digital currents; exposed pad must be soldered to PCB ground plane. |
| V+ | Positive supply input | Single power rail (1.6–4.2V); powers analog switch core and logic interface; bypass with 0.1μF capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 5ns minimum dead time prevents short-through during channel switching-critical for power domain isolation. |
| Rail-to-rail analog signal handling | Supports input/output signals from 0V to V+ without clipping-enables full dynamic range use in audio and sensor interfaces. |
| Ultra-low quiescent power | <4μW at 3V-extends battery life in portable medical monitors, wearables, and handheld test equipment. |
| Low RON flatness | 0.05Ω max over 0–3V signal range-maintains consistent gain and linearity across full analog input span. |
| High off-isolation & low crosstalk | −52dB off-isolation and −78dB crosstalk at 1MHz-preserves signal integrity in multi-channel video/audio matrix routing. |

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 |
|---|---|---|---|

FAQ
What is the maximum continuous current rating for MAX4736EUB+T analog terminals?
The MAX4736EUB+T supports ±300mA continuous current on COM_, NO_, and NC_ terminals. This rating applies across the full operating temperature range (−40°C to +85°C) and ensures reliable operation in power-routing and sensor-multiplexing applications without thermal derating under typical PCB copper area conditions. The device also handles ±500mA peak current (1ms, 10% duty cycle) for transient loads.
Does MAX4736EUB+T support rail-to-rail analog signal switching?
Yes, the MAX4736EUB+T supports rail-to-rail analog signals from 0V to V+ on all COM_, NO_, and NC_ terminals. This capability is enabled by its CMOS switch architecture and allows full utilization of the supply voltage range-critical for preserving dynamic range in audio, sensor, and data-acquisition circuits without signal clipping or distortion.
What is the logic voltage compatibility of MAX4736EUB+T inputs at 3V supply?
At a 3V supply, the MAX4736EUB+T logic inputs (IN1/IN2) are 1.8V CMOS compatible, with VIH = 1.4V (minimum) and VIL = 0.5V (maximum). This allows direct interfacing with 1.8V microcontrollers and FPGAs without external level shifters, reducing BOM count and layout complexity in low-voltage embedded systems.
How does the break-before-make feature function in MAX4736EUB+T?
The MAX4736EUB+T guarantees break-before-make switching with a minimum 5ns dead time between disconnecting one path and connecting another. This prevents momentary shorting between NO and NC terminals during state transitions-essential for avoiding supply rail contention in power routing and ensuring signal integrity in multi-source analog systems.
What package type and thermal considerations apply to MAX4736EUB+T?
The MAX4736EUB+T uses a 10-pin μMAX package (3mm × 3mm) with an exposed pad that must be soldered to the PCB ground plane. This pad provides both thermal dissipation (444mW max at +70°C) and low-impedance grounding for analog performance. Proper thermal land pattern and solder paste stencil design are required to ensure mechanical reliability and optimal junction temperature control.
