Product details
Overview
MAX4736EGC+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 routes rail-to-rail analog signals in battery-powered audio/video systems and low-voltage data-acquisition circuits.
For engineers reviewing the MAX4736EGC+T datasheet, MAX4736EGC+T pinout, MAX4736EGC+T application, or MAX4736EGC+T equivalent, key selection criteria include on-resistance matching (0.1Ω max), CMOS-compatible logic inputs at 1.8V supply, and TQFN-12 package compatibility with exposed pad grounding.
Technical Context
The MAX4736EGC+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. Its break-before-make timing (5ns typical) prevents signal shorting during state transitions.
It supports bidirectional analog signal routing from GND to V+, with leakage currents below ±10nA over temperature and supply voltage. Charge injection is limited to 60pC (3V) and 35pC (1.8V), enabling precision signal switching without significant transient disturbance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.6V to 4.2V single supply - enables direct integration into Li-ion and coin-cell powered systems without level-shifting. |
| On-Resistance (RON) | 0.6Ω typ at 3V - minimizes voltage drop and power loss in high-current analog paths up to ±300mA continuous. |
| RON Matching | 0.1Ω max at 3V - ensures matched gain/attenuation across dual channels for differential or stereo signal routing. |
| Switching Speed | tON = 25ns, tOFF = 20ns max - supports high-speed multiplexing in communications and modem applications. |
| Logic Compatibility | 1.8V CMOS input threshold at 3V supply - allows direct interfacing with low-voltage microcontrollers and FPGAs. |
| Off-Isolation | -52dB at 1MHz - suppresses crosstalk between active and inactive signal paths in multi-channel routing. |
| Charge Injection | 60pC at 3V - limits output glitch amplitude in sample-and-hold or ADC front-end configurations. |
Pinout & Package
The MAX4736EGC+T is housed in a 12-pin TQFN package (3mm × 3mm) with exposed pad requiring connection to GND for thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 12 | IN1 / IN2 | Digital control inputs for Switch 1 and Switch 2 - TTL/CMOS compatible, accept 0–3.6V regardless of V+. |
| 2, 3 | NO1 / NO2 | Normally open analog terminals - connect to signal path only when corresponding IN_ is high. |
| 4, 5 | COM1 / COM2 | Common analog terminals - serve as bidirectional I/O ports for routed signals. |
| 7, 9 | NC1 / NC2 | Normally closed analog terminals - conduct when corresponding IN_ is low; disconnect on logic high. |
| 6, 8, 10, 11 | N.C. / V+ / GND / EP | V+ supplies internal circuitry; GND and exposed pad (EP) must be tied to system ground for stability and thermal dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 5ns minimum interval prevents momentary short-circuit between NO and NC paths during transition. |
| Rail-to-rail analog signal handling | Supports input/output signals from GND to V+ without clipping - essential for full-scale audio and sensor interfaces. |
| Ultra-low quiescent power | <4μW typical - extends battery life in portable devices such as cellular phones and modems. |
| Low RON flatness | 0.05Ω max at 3V - maintains consistent on-resistance across the entire analog signal range (0–3V), reducing distortion. |
| Exposed thermal pad | EP pin connected to GND improves thermal resistance by >30% versus non-exposed packages - critical for sustained 300mA operation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4737ETC+T | Dual SPST (not SPDT); no NC path - requires external routing for normally closed functionality. | Lacks break-before-make and dual-path flexibility - suitable only for simple on/off control, not signal path selection. | Select MAX4737ETC+T only when SPST topology suffices and board layout accommodates external NC path implementation. |
| TMUX1574RTER | Single-supply 1.08V–3.6V; 0.5Ω RON at 3V but higher 10nA leakage at +85°C. | Optimized for ultra-low voltage IoT sensors; less suited for audio due to higher THD (0.03% vs. 0.018%). | Prefer TMUX1574RTER for sub-1.8V systems where MAX4736EGC+T's 1.6V minimum does not meet margin requirements. |
Compared with MAX4736EGC+T, the MAX4737ETC+T sacrifices SPDT flexibility for lower cost and smaller footprint, while the TMUX1574RTER trades off audio-grade distortion performance for broader ultra-low-voltage operation - making MAX4736EGC+T optimal for balanced analog routing where both NO and NC paths and low THD are required.

FAQ
What is the maximum continuous current rating for the MAX4736EGC+T analog switches?
The MAX4736EGC+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 for reliable operation in power-routing and battery-management applications. Exceeding this limit risks thermal overstress and long-term reliability degradation in the MAX4736EGC+T.
Does the MAX4736EGC+T require external bypass capacitors, and if so, what value is recommended?
Yes, a 0.1μF ceramic capacitor placed between V+ and GND, as close as possible to the MAX4736EGC+T pins, is recommended to improve noise margin and suppress switching transients. This bypassing reduces supply-induced crosstalk and stabilizes internal bias networks, especially critical when the MAX4736EGC+T operates near its 1.6V lower supply limit.
Can the MAX4736EGC+T operate with analog signals exceeding the V+ supply rail?
No - the MAX4736EGC+T analog terminals (COM_, NO_, NC_) are rated for signals from -0.3V to (V+ + 0.3V). Signals beyond this range forward-bias internal ESD diodes, risking damage unless current is externally limited to ≤±300mA. For true rail-to-rail operation, the MAX4736EGC+T must be used with analog signals strictly within GND to V+.
How does the break-before-make timing of the MAX4736EGC+T affect signal integrity in audio applications?
The MAX4736EGC+T guarantees ≥5ns break-before-make delay, preventing momentary shorting between NO and NC paths during switching. In audio routing, this eliminates audible "pops" caused by transient shorts and preserves channel isolation - particularly important when toggling between microphone and speaker paths in the MAX4736EGC+T-based designs.
Is the exposed pad (EP) on the MAX4736EGC+T package electrically connected internally, and how should it be handled on the PCB?
Yes, the exposed pad (EP) on the MAX4736EGC+T is internally connected to GND and must be soldered to a solid PCB ground plane. This connection provides critical thermal dissipation (reducing junction temperature rise by >20°C at full load) and lowers ground impedance, directly improving noise immunity and switching consistency in the MAX4736EGC+T.
