Product details
Overview
MAX4736EGC+TGH7 from Maxim Integrated is a dual SPDT analog switch with 0.8Ω max on-resistance (at 3V), break-before-make switching, and rail-to-rail signal handling from GND to V+. It operates from a single 1.6V–3.6V supply, delivers 25ns turn-on/20ns turn-off times, and supports 150mA continuous current per channel-ideal for low-voltage audio routing and battery-powered data acquisition.
For engineers reviewing the MAX4736EGC+TGH7 datasheet, MAX4736EGC+TGH7 pinout, MAX4736EGC+TGH7 application, or MAX4736EGC+TGH7 equivalent, key selection criteria include on-resistance flatness (0.1Ω max), 1.8V CMOS logic compatibility at 3V supply, QFN-12 package thermal performance (1176mW at +70°C), and guaranteed break-before-make timing (5ns max).
Technical Context
The MAX4736EGC+TGH7 implements two independent CMOS-based SPDT switches with separate digital control inputs (IN1/IN2), each selecting between a normally open (NO) and normally closed (NC) path to a common terminal (COM). Its architecture ensures bidirectional analog signal flow and maintains low RON variation (<0.1Ω flatness) across the full 0–V+ signal range.
Break-before-make timing (5ns typical) prevents momentary shorting during state transitions, while charge injection (60pC max) and off-isolation (−52dB at 1MHz) are optimized for precision signal routing in communications and audio paths. The device draws only 1µA quiescent supply current and features 1.8V logic-compatible inputs even when powered from 3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 0.8Ω max at V+ = 2.7V - enables high-current analog routing with minimal voltage drop |
| RON flatness | 0.1Ω max at V+ = 2.7V - ensures consistent gain and linearity across full signal swing |
| Switching speed | tON = 25ns, tOFF = 20ns max - supports high-speed multiplexing in data-acquisition systems |
| Supply range | 1.6V to 3.6V single supply - compatible with Li-ion, coin-cell, and low-power MCU rails |
| Logic compatibility | 1.8V CMOS input threshold at 3V supply - interfaces directly with modern low-voltage digital controllers |
| Continuous current | ±150mA per COM/NO/NC terminal - handles audio line drivers and sensor signal conditioning loads |
| Off-isolation | −52dB at 1MHz - suppresses crosstalk between active and inactive channels in multi-signal systems |
Pinout & Package
MAX4736EGC+TGH7 is housed in a 12-pin QFN package (3mm × 3mm × 0.85mm, exposed pad) rated for −40°C to +85°C operation. Thermal resistance θJA is 85°C/W, enabling 1176mW power dissipation at +70°C ambient with standard PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1, IN2 | Digital control inputs | CMOS-compatible logic signals that select NO/NC path for respective SPDT switch |
| COM1, COM2 | Analog common terminals | Bidirectional signal ports connecting to system source/load; support rail-to-rail voltage swing |
| NO1, NO2 | Normally open analog terminals | Open-circuit when INx = LOW; connect to COMx only when INx = HIGH |
| NC1, NC2 | Normally closed analog terminals | Connected to COMx when INx = LOW; disconnect when INx = HIGH (break-before-make) |
| V+ | Positive supply input | Single 1.6V–3.6V rail powering analog and digital sections; requires 0.1µF bypass to GND |
| GND | Ground reference | Common return for supply, logic, and analog signals; must be low-impedance for THD < 0.018% |
| N.C. (pins 6, 10) | No connection | Unbonded pads - must remain unconnected and unstubbed on PCB layout |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports 0V to V+ input/output swing without clipping or distortion - critical for audio and sensor front-ends |
| Break-before-make switching | Guaranteed 5ns minimum dead time prevents signal shorting during path transitions - essential for power routing safety |
| Low 60pC charge injection | Minimizes transient glitches on sensitive nodes like ADC inputs or op-amp feedback paths |
| 0.2Ω RON matching between channels | Ensures matched gain and phase response in differential or stereo signal paths |
| 1.8V logic compatibility at 3V supply | Eliminates level-shifter requirements when interfacing with 1.8V FPGAs or microcontrollers |

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 |
|---|---|---|---|
| MAX4737EGC+TGH7 | Same pinout and electrical specs, but includes enable (EN) pin for global switch control | Required where system-level power gating or simultaneous channel disable is needed | Select MAX4737EGC+TGH7 if centralized ON/OFF control across both switches is required; otherwise MAX4736EGC+TGH7 offers simpler logic interface |
| TMUX1574RTER | Lower RON (0.5Ω typ), higher supply range (1.08V–3.6V), but no break-before-make guarantee | Suitable for ultra-low-RON applications where short-through risk is mitigated by external logic | Choose TMUX1574RTER only if RON < 0.6Ω is mandatory and break-before-make is managed externally |
Compared with MAX4737EGC+TGH7, the MAX4736EGC+TGH7 lacks an EN pin but simplifies control logic; versus TMUX1574RTER, it guarantees break-before-make timing and offers tighter RON matching (0.2Ω vs. 0.5Ω), making it preferable for safety-critical or precision-matched routing.

FAQ
What is the maximum continuous current rating for MAX4736EGC+TGH7?
The MAX4736EGC+TGH7 supports ±150mA continuous current per COM, NO, or NC terminal when operating within its specified temperature and voltage ranges. This rating applies to both analog signal paths and is validated under worst-case thermal conditions in the 12-pin QFN package. Exceeding this current may increase on-resistance drift or trigger internal thermal shutdown mechanisms not explicitly defined in the datasheet.
Does MAX4736EGC+TGH7 require external level shifters when interfaced with 1.8V logic?
No, the MAX4736EGC+TGH7 does not require external level shifters when used with 1.8V logic driving its IN1/IN2 pins - its logic inputs are 1.8V CMOS compatible when powered from a 3V supply. Input thresholds (VIH = 1.4V, VIL = 0.5V) ensure reliable recognition of 1.8V logic levels, and input leakage remains below ±1µA across temperature.
How does the break-before-make feature function in MAX4736EGC+TGH7?
The MAX4736EGC+TGH7 guarantees break-before-make operation with a minimum 5ns dead time between disconnecting one path and connecting the other within each SPDT switch. This prevents momentary shorting between NO and NC terminals during state transitions, which is critical for protecting downstream circuitry in power routing or signal multiplexing applications.
Can MAX4736EGC+TGH7 handle analog signals beyond the supply rails?
No, the MAX4736EGC+TGH7 cannot safely handle analog signals exceeding the supply rails: the absolute maximum rating for COM_, NO_, and NC_ pins is (V+ + 0.3V) and −0.3V. Signals outside the 0V to V+ range will forward-bias internal ESD diodes, potentially causing latch-up or increased leakage. Rail-to-rail operation means full utilization of the V+ to GND range-not beyond it.
What is the thermal performance of the MAX4736EGC+TGH7 QFN package?
The MAX4736EGC+TGH7 in its 12-pin QFN package has a thermal resistance θJA of 85°C/W and supports 1176mW continuous power dissipation at +70°C ambient. This assumes standard JEDEC 2-layer board layout with exposed pad soldered to internal ground plane. Derating is 14.7mW/°C above +70°C, enabling reliable operation up to +85°C junction temperature under typical load conditions.
