Product details
Overview
MAX4734EUB+T from Maxim Integrated is a low-voltage, 4-channel CMOS analog multiplexer with break-before-make switching, 0.8Ω max on-resistance at 3V supply, 25ns turn-on time, and rail-to-rail signal handling (0V to V+). It operates from a single 1.6V–3.6V supply and delivers <4μW quiescent power-ideal for battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4734EUB+T datasheet, MAX4734EUB+T pinout, MAX4734EUB+T application, or MAX4734EUB+T equivalent, this page provides verified electrical parameters, μMAX package layout details, functional truth table mapping, and validated alternatives for portable and space-constrained designs.
Technical Context
The MAX4734EUB+T implements a 2-bit address-decoded 4:1 analog switch architecture using CMOS transmission gates. Its break-before-make timing (5ns typical) prevents momentary shorting during channel transitions, critical in power routing and signal integrity-sensitive applications.
All four normally-open (NO1–NO4) channels share a common analog terminal (COM), with digital control via A0/A1 address inputs and an active-high EN enable. Logic inputs tolerate up to 3.6V regardless of supply voltage, enabling mixed-voltage interface with 1.8V CMOS controllers when powered from 3V.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 0.8Ω max at V+ = 2.7V, 100mA - enables high-current analog routing without significant voltage drop |
| RON Matching | 0.2Ω max - ensures consistent gain/attenuation across channels in multi-path signal selection |
| Turn-On/Off Time | tON = 25ns, tOFF = 20ns max - supports >10MHz switching in high-speed data acquisition |
| Analog Signal Range | 0V to V+ (rail-to-rail) - preserves full dynamic range of baseband audio and sensor signals |
| Supply Voltage Range | 1.6V to 3.6V single supply - compatible with Li-ion, coin-cell, and regulated 1.8V/2.5V/3.3V rails |
| Quiescent Supply Current | 1μA max - extends battery life in always-on portable instrumentation |
| Channel Leakage | ±5nA max off-leakage (COM/NO) - minimizes DC error in precision sensor front-ends |
Pinout & Package
MAX4734EUB+T uses a 10-pin μMAX package (3mm × 3mm, 0.5mm pitch), RoHS-compliant and lead-free. Exposed pad (EP) must be connected to GND for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NO1 | Analog Switch Channel 1 Output | Normally open terminal for first selected path; bidirectional signal flow |
| 2 GND | Ground Reference | Primary return path for analog and digital circuits; connects to EP |
| 3 NO3 | Analog Switch Channel 3 Output | Third selectable analog path; identical RON and bandwidth to NO1/NO2/NO4 |
| 4 EN | Enable Input (Active-High) | Global enable: all switches off when low; overrides A0/A1 address logic |
| 5 N.C. | No Connection | Not internally bonded; leave unconnected or tie to GND per layout best practice |
| 6 V+ | Positive Supply Input | Single 1.6V–3.6V analog/digital supply; requires local 0.1μF bypass to GND |
| 7 NO4 | Analog Switch Channel 4 Output | Fourth selectable path; shares same timing and leakage specs as other NOx pins |
| 8 COM | Common Analog Terminal | Shared I/O node for all four channels; handles ±150mA continuous current |
| 9 NO2 | Analog Switch Channel 2 Output | Second selectable path; pin-compatible with NO1/NO3/NO4 in routing |
| 10 A1 | Address Bit 1 Input | MSB of 2-bit channel select; 1.8V CMOS-compatible with 3V supply |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+T | Single SPST switch, 3Ω RON (3V), no address decoding, 10-pin μMAX | Lacks 4-channel selection logic; suited only for on/off gating, not multiplexing | Select when only one path needs enable/disable control and lower cost is prioritized over channel count |
| TMUX1574RSVR | 4-channel mux, 0.5Ω RON (3.3V), 1.08V–3.6V supply, 10-pin WSON | Lower RON but requires ≥1.08V logic threshold; no break-before-make guarantee | Prefer for ultra-low RON requirements where BBM is not critical and WSON footprint is acceptable |
Compared with MAX4734EUB+T, MAX4617EUA+T reduces functionality to basic switching and increases RON by 275%, while TMUX1574RSVR improves RON by 37.5% but removes BBM assurance and changes package-making MAX4734EUB+T optimal for reliable, low-distortion, multi-channel routing in constrained 3V battery systems.

FAQ
What is the maximum continuous current rating for MAX4734EUB+T?
The MAX4734EUB+T supports ±150mA continuous current through its COM and NOx terminals. This rating applies across the full -40°C to +85°C operating temperature range and enables direct routing of sensor excitation, microphone bias, or LED drive currents without external buffering. The 0.8Ω max on-resistance ensures voltage drop remains below 120mV at 150mA, preserving signal integrity in precision applications.
Does MAX4734EUB+T support rail-to-rail analog signal switching?
Yes, MAX4734EUB+T fully supports rail-to-rail analog signal switching from 0V to V+, with minimal variation in on-resistance across the entire range. At V+ = 3.0V, RON flatness is guaranteed at 0.1Ω max, ensuring consistent performance for audio, sensor, and communication signals that span the full supply rail-critical for maintaining THD below 0.018% and preserving dynamic range.
Is MAX4734EUB+T pin-compatible with other packages in the MAX4734 family?
No, MAX4734EUB+T (10-pin μMAX) is not pin-compatible with the 12-pin TQFN variants (e.g., MAX4734ETC+T). Pin counts, layouts, and terminal assignments differ: μMAX places A0 on pin 10 and A1 on pin 1, while TQFN assigns A0 to pin 12 and A1 to pin 10. PCB layout must be specific to the μMAX footprint; no mechanical or electrical interchangeability exists between packages.
What logic voltage levels are compatible with MAX4734EUB+T inputs?
MAX4734EUB+T logic inputs (A0, A1, EN) accept voltages up to 3.6V regardless of supply voltage, making them compatible with 1.8V CMOS logic when V+ = 3.0V (VIH = 1.4V min, VIL = 0.5V max). This eliminates level shifters in mixed-voltage systems. Input leakage remains ≤±1µA, minimizing power impact on driving controllers.
How does break-before-make timing affect system design with MAX4734EUB+T?
MAX4734EUB+T guarantees a 5ns minimum break-before-make (BBM) interval, preventing momentary shorting between channels during address transitions. This eliminates cross-talk spikes and supply contention in power routing or multi-source signal selection-enabling safe use in battery management, RF front-end switching, and shared ADC architectures without external protection circuitry.
