Product details
Overview
The MAX4704EUB+T from Maxim Integrated is a low-voltage, 4:1 analog multiplexer IC operating from a single +1.8V to +5.5V supply, featuring 60Ω max on-resistance at +2.7V, 60ns turn-on time, and break-before-make switching. It routes audio/video signals in battery-powered portable devices with rail-to-rail signal handling and <200MHz -3dB bandwidth.
For engineers reviewing the MAX4704EUB+T datasheet, MAX4704EUB+T pinout, MAX4704EUB+T application, or MAX4704EUB+T equivalent, this page delivers verified electrical parameters, QFN/µMAX package mapping, real-world use cases in MP3 players and cellular phones, and two validated alternative parts for low-voltage analog switching designs.
Technical Context
The MAX4704EUB+T implements a CMOS-based 4-channel analog switch matrix controlled by dual address bits (ADDA, ADDB) and an active-low inhibit (INH) input. Its break-before-make architecture prevents momentary shorting between channels during switching transitions, with tBBM ≤2ns guaranteed across temperature.
It supports rail-to-rail analog signal ranges (0V to V+), maintains RON flatness ≤5Ω over full signal swing, and achieves -90dB crosstalk and -85dB off-isolation at 1MHz-enabling high-fidelity signal routing without channel interference or leakage-induced distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +1.8V to +5.5V single supply - enables direct integration into 1.8V, 2.7V, 3.3V, and 5V systems without level shifters |
| On-Resistance (RON) | 60Ω max at +2.7V - ensures minimal signal attenuation and voltage drop in low-power sensor/audio paths |
| RON Matching | 3Ω max between channels - guarantees consistent gain and timing across all four switched paths |
| Switching Speed | tON = 60ns, tOFF = 20ns at +3V - supports fast data acquisition and real-time signal reconfiguration |
| Charge Injection | 3pC max - minimizes glitch-induced error in precision sampling and DAC output switching |
| Crosstalk | -90dB at 1MHz - prevents audible artifacts or data corruption when routing adjacent audio/video channels |
| Off-Isolation | -85dB at 1MHz - blocks unwanted coupling from inactive channels into sensitive analog front-ends |
Pinout & Package
The MAX4704EUB+T is packaged in a 10-pin µMAX (3mm × 3mm) with exposed pad thermal enhancement. Pin 2 and Pin 8 are no-connect (N.C.) terminals; the exposed pad is internally tied to GND and must be soldered to a ground plane for optimal thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Accepts +1.8V to +5.5V; powers internal CMOS switches and logic; must be applied before analog signals |
| GND | Ground reference | Return path for supply and analog signals; connects to exposed pad in µMAX package |
| COM | Common analog terminal | Bidirectional I/O node connected to selected NOx channel; handles rail-to-rail signals |
| NO0–NO3 | Normally-open analog inputs/outputs | Four independent analog paths; each electrically isolated when unselected; bidirectional operation supported |
| ADDA / ADDB | Dual-bit address decoder inputs | Select one of four NOx channels (00→NO0, 01→NO1, 10→NO2, 11→NO3); TTL/CMOS compatible |
| INH | Active-low inhibit control | Pulls all switches open when high; enables global disable without changing address lines |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog voltages from GND to V+ without clipping or distortion-critical for full-scale audio and sensor outputs |
| Break-before-make switching | Guarantees ≥2ns dead time between channel disconnect and reconnect-eliminates transient shorts in multiplexed power/signal paths |
| 1.8V logic compatibility | Accepts 1.4V VIH and 0.5V VIL thresholds at +2.7V supply-enables direct interface with ultra-low-voltage microcontrollers |
| Low THD (0.02%) | Maintains signal fidelity across 20Hz–20kHz audio band-suitable for high-quality headset and speaker routing |
| Low leakage (≤1nA) | Minimizes DC offset and settling errors in high-impedance sensor interfaces and precision data acquisition |

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; 35Ω RON at +3V; no address decoding; requires external logic for 4:1 function | Requires 4× ICs + glue logic to replicate MAX4704EUB+T's integrated 4:1 functionality | Choose only if discrete switch control and board area are less critical than cost per switch |
| TMUX1104DSCR | 4:1 mux; 1.5Ω RON at +5V; 1.8V logic compatible; but 16-pin WQFN, higher supply current (10μA vs. 1μA) | Superior RON and bandwidth, but larger footprint and higher quiescent power limits battery life in portable designs | Prefer for high-speed industrial DAQ where RON matching <1Ω is mandatory; avoid for space-constrained wearables |
Compared with MAX4704EUB+T, MAX4617EUA+T lacks integrated addressing and increases component count, while TMUX1104DSCR improves RON and bandwidth at the expense of size and static current-making MAX4704EUB+T optimal for compact, low-quiescent-power portable analog routing.

FAQ
What is the maximum supply voltage rating for the MAX4704EUB+T?
The MAX4704EUB+T has an absolute maximum supply voltage (V+) of +6V. Operation beyond this limit risks permanent damage. The device is specified for reliable operation from +1.8V to +5.5V, with on-resistance and switching times optimized across that range. At +5.5V, RON drops to 40Ω max, improving signal fidelity in higher-voltage systems.
Does the MAX4704EUB+T support bidirectional analog signal flow?
Yes, the MAX4704EUB+T supports fully bidirectional analog signal routing. Both the COM and NO0–NO3 pins function interchangeably as inputs or outputs, enabling flexible signal path design-for example, using COM as input and NOx as outputs, or vice versa-without performance degradation or polarity constraints.
How does the inhibit (INH) pin function in the MAX4704EUB+T?
The INH pin on the MAX4704EUB+T is an active-low global disable control. When pulled high (≥VIH), it forces all four analog switches into the open (off) state regardless of ADDA/ADDB states. When grounded (≤VIL), normal 4:1 multiplexing resumes. This allows rapid system-level shutdown without altering address logic.
What is the guaranteed on-resistance matching specification for the MAX4704EUB+T?
The MAX4704EUB+T guarantees on-resistance matching (ΔRON) of ≤3Ω maximum between any two channels at +2.7V supply and +25°C. This tight matching ensures uniform gain, phase, and settling behavior across all four switched paths-essential for applications like multi-channel sensor scanning where channel-to-channel consistency directly impacts measurement accuracy.
Can the MAX4704EUB+T operate with a 1.8V logic interface while powered from a 3.3V supply?
Yes, the MAX4704EUB+T supports 1.8V CMOS logic compatibility when powered from +2.7V to +3.3V supplies. Its VIH threshold is guaranteed at +1.4V min and VIL at +0.5V max, allowing direct connection to 1.8V GPIOs without level-shifting circuitry-reducing BOM count and PCB complexity in mixed-voltage portable designs.
