Product details
Overview
The MAX4733EUA+T from Maxim Integrated is a dual SPST analog switch IC featuring one normally open (NO) and one normally closed (NC) channel, designed for low-voltage signal routing in space-constrained systems. It operates from a single +2V to +11V supply, delivers 50Ω max on-resistance at +3V, 3.5Ω max on-resistance matching, and <0.1nA leakage current at +25°C-enabling precision battery-powered audio and data-acquisition paths.
For engineers reviewing the MAX4733EUA+T datasheet, MAX4733EUA+T pinout, MAX4733EUA+T application, or MAX4733EUA+T equivalent, this device is selected for rail-to-rail analog switching with break-before-make timing (1ns), ultra-low quiescent power (0.5nW typ), and µMAX package compatibility in portable instrumentation and communications circuits.
Technical Context
The MAX4733EUA+T implements two independent CMOS SPST switches-one NO and one NC-controlled by separate TTL/CMOS-compatible digital inputs (IN1, IN2). Its internal architecture ensures guaranteed on-resistance flatness (9Ω max at +3V) and low charge injection (7.5pC), critical for minimizing signal distortion in multiplexed sensor or audio paths.
It supports single-supply operation across +2V to +11V, with logic thresholds scaling with V+: VIH = +2.0V min (independent of supply), VIL = +0.8V max. Break-before-make timing (tBBM = 1ns) is specified exclusively for the MAX4733 variant to prevent momentary shorting during channel switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2.0V to +11V - enables direct integration into Li-ion, 3.3V, and 5V systems without level-shifting. |
| On-Resistance (RON) | 50Ω max at +3V - ensures minimal insertion loss and voltage drop in low-level analog signal paths. |
| On-Resistance Matching | 3.5Ω max at +3V - maintains channel-to-channel gain consistency in differential or dual-path routing. |
| Leakage Current | <0.1nA at +25°C - preserves accuracy in high-impedance sensor front-ends and battery-monitoring circuits. |
| Break-Before-Make Time | 1ns - prevents transient conduction between NO and NC channels during state transitions. |
| Off-Isolation | −72dB at 1MHz - suppresses crosstalk between inactive and active signal paths in dense AFE layouts. |
| Bandwidth | 300MHz - supports high-fidelity routing of audio, video, and baseband RF signals without attenuation. |
Pinout & Package
The MAX4733EUA+T is housed in an 8-pin µMAX® package (3.0mm × 3.0mm, 0.8mm height), with exposed pad (EP) connected to V+ for thermal and electrical stability. Pin 1 is NO1; pin 2 is IN1; pin 3 is IN2; pin 4 is NO2 (for MAX4731) - but for MAX4733, pin 4 is NC2 per functional diagram and pin description table.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO1 | Normally open analog terminal - connects to COM1 only when IN1 = logic high. |
| 2 | IN1 | Digital control input for NO1/COM1 switch - TTL/CMOS compatible, rail-to-rail driven. |
| 3 | IN2 | Digital control input for NC2/COM2 switch - independent logic control enables asymmetric routing. |
| 4 | NC2 | Normally closed analog terminal - disconnects from COM2 only when IN2 = logic high. |
| 5 | COM2 | Common analog node for NC2 channel - bidirectional, supports rail-to-rail signal swing. |
| 6 | GND | Digital ground reference - must be low-impedance connection to minimize noise coupling. |
| 7 | COM1 | Common analog node for NO1 channel - shared return path for dual-switch topology. |
| 8 | V+ | Positive supply input - bypass with ≥0.1µF capacitor near pin for stable operation up to +11V. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 1ns tBBM ensures no overlap between NO1 and NC2 conduction states. |
| Rail-to-rail analog handling | Supports full GND-to-V+ signal range with <9Ω RON flatness - preserves linearity in ADC/DAC interfaces. |
| Ultra-low quiescent power | 0.5nW typical supply current - extends battery life in always-on monitoring and wearable devices. |
| Low charge injection | 7.5pC - minimizes voltage glitches at COM nodes during switching, critical for precision sampling. |
| High off-isolation | −72dB at 1MHz - isolates unused signal paths in multi-source audio/video routing applications. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4733ETA+ | Same die, 8-pin TDFN-EP package with exposed pad tied to V+; 3×3mm footprint vs. µMAX's 3×3mm but different pinout and thermal profile. | Preferred for higher-power dissipation or PCB space optimization where EP soldering is supported. | Select MAX4733ETA+ when board layout allows exposed-pad reflow and thermal management exceeds µMAX limits. |
| ADG733BRUZ | Triple SPST, 16-pin TSSOP; 4.5Ω RON at +3V, but no break-before-make guarantee; −80dB off-isolation. | Suitable for 3-channel routing but lacks MAX4733EUA+T's dedicated NO/NC pairing and tBBM assurance. | Choose ADG733BRUZ only if third switch channel is required and break-before-make is not safety-critical. |
Compared with MAX4733ETA+ and ADG733BRUZ, the MAX4733EUA+T uniquely combines NO/NC duality, guaranteed 1ns break-before-make, and µMAX package compatibility-making it optimal for compact, safety-aware analog routing where channel independence and transient-free switching are mandatory.

FAQ
What is the maximum supply voltage rating for the MAX4733EUA+T?
The MAX4733EUA+T has an absolute maximum supply voltage (V+) of +12V, but its recommended operating range is +2.0V to +11V. Operation above +11V risks exceeding safe operating area limits and is not guaranteed. For reliable long-term performance at +11V, a minimum 0.1µF bypass capacitor must be placed directly at the V+ pin to ground.
Does the MAX4733EUA+T support rail-to-rail analog signal operation?
Yes, the MAX4733EUA+T supports true rail-to-rail analog signal handling from GND to V+, with on-resistance flatness maintained at ≤9Ω over the full signal range at +3V. This allows undistorted passage of signals spanning the entire supply, essential for interfacing with ADCs, DACs, and op-amps without external level-shifting circuitry.
What is the function of Pin 4 on the MAX4733EUA+T?
Pin 4 on the MAX4733EUA+T is NC2 - the normally closed analog terminal for the second switch channel. When IN2 is logic low, NC2 is connected to COM2; when IN2 is logic high, the connection opens. This differs from the MAX4731 (Pin 4 = NO2) and MAX4732 (Pin 4 = NC2), confirming the MAX4733EUA+T's unique NO1/NC2 configuration.
How does the break-before-make timing work in the MAX4733EUA+T?
The MAX4733EUA+T guarantees a 1ns break-before-make interval (tBBM) between NO1 and NC2 switching events, preventing momentary shorting during transition. This is intrinsic to the MAX4733 family and verified under load conditions (RL = 300Ω, CL = 35pF). It applies only to the interaction between the two channels-not within a single switch-and is not present in MAX4731 or MAX4732 variants.
Can the MAX4733EUA+T operate from a 1.8V supply?
No, the MAX4733EUA+T requires a minimum supply voltage of +2.0V per Absolute Maximum Ratings and Electrical Characteristics tables. At 1.8V, the device falls outside its specified operating range: logic thresholds become undefined, on-resistance increases significantly, and leakage current may exceed guaranteed limits - risking functional failure or parametric noncompliance.
