Product details
Overview
The MAX4051EEE+T from Maxim Integrated is an 8-channel CMOS analog multiplexer configured as a single-pole, eight-throw (SP8T) switch with rail-to-rail signal handling, 100Ω typical on-resistance at ±5V supplies, 0.1nA max off-leakage at +25°C (A-suffix variant), and TTL/CMOS logic compatibility. It operates from single +2.7V to +16V or dual ±2.7V to ±8V supplies and is used in low-voltage data-acquisition systems for channel selection.
For engineers reviewing the MAX4051EEE+T datasheet, MAX4051EEE+T pinout, MAX4051EEE+T application, or MAX4051EEE+T equivalent, key selection criteria include guaranteed on-resistance matching (6Ω max between channels), low charge injection (2pC typ), high off-isolation (<–90dB at 100kHz), and QSOP-16 package compatibility with legacy 74HC4051 layouts.
Technical Context
The MAX4051EEE+T implements a CMOS transmission-gate architecture with independent V+, V-, and GND supply pins. Its digital address decoding (ADDA/ADDB/ADDC) selects one of eight NOx inputs to connect to the COM terminal, while INH enables global disable. The A-suffix denotes full characterization of on-resistance match and flatness.
It supports break-before-make switching with 30ns typical tOPEN at +25°C under single +5V operation, and maintains <0.04% THD into 600Ω loads. Signal paths are bidirectional and ground-referenced only via ESD diodes - no internal connection exists between analog signals and GND.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (SP8T); one COM, eight NO terminals |
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation in precision sensor routing |
| On-resistance match | 6Ω max (MAX4051A) - critical for matched gain paths in instrumentation amplifiers |
| Off-leakage current | 0.1nA max at +25°C - preserves accuracy in high-impedance pH or thermocouple front-ends |
| Supply range | +2.7V to +16V single or ±2.7V to ±8V dual - enables direct interface with Li-ion battery or industrial ±5V rails |
| Logic thresholds | 0.8V to 2.4V - guarantees reliable switching with 3.3V or 5V microcontrollers without level shifters |
| Off-isolation | <–90dB at 100kHz (50Ω) - prevents crosstalk between adjacent channels in multi-signal systems |
Pinout & Package
MAX4051EEE+T is supplied in a 16-pin QSOP package (5.3mm × 10.2mm, 0.635mm pitch), RoHS-compliant and moisture-sensitive level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog switch terminals - interchangeable as inputs or outputs; support bidirectional rail-to-rail signals |
| 3 | COM | Common analog terminal - connects to selected NOx channel; no internal ground reference |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - decode 000–111 to select NO0–NO7; CMOS/TTL compatible |
| 6 | INH | Digital inhibit input - logic high disables all switches; tied low for normal operation |
| 7 | V− | Negative analog supply - connected to GND for single-supply use; sets lower analog voltage limit |
| 8 | GND | Digital ground reference - powers internal logic; no analog current path to this pin |
| 16 | V+ | Positive analog/digital supply - powers transmission gates and logic; defines upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement in existing PCBs using standard 16-pin SO/QSOP footprints |
| Guaranteed RON match | 6Ω max across all 8 channels - eliminates gain error in multi-channel ADC front-ends |
| Low charge injection | 2pC typical - minimizes voltage glitch during switching in sample-and-hold circuits |
| Rail-to-rail analog range | V− to V+ - supports full-scale signal routing without clipping in ±5V or +12V systems |
| High off-isolation | <–90dB at 100kHz - suppresses interference between unused and active channels in RF-adjacent designs |
Applications
| Battery-Operated Data Loggers | Audio Signal Routing |
|---|---|
Use Scenario: Multiplexing thermistor, RTD, and strain gauge inputs into a single SAR ADC in portable environmental monitors. IC Role / Device Role / Timing Role: Analog multiplexer providing channel selection under microcontroller GPIO control; tON/tOFF < 200ns enables rapid scanning. Use Value: 0.1nA off-leakage prevents measurement drift in >10MΩ sensor bridges; 100Ω RON adds <0.1% gain error. | Use Scenario: Routing line-level stereo signals between multiple sources (DAC, Bluetooth module, aux input) to a headphone amplifier. IC Role / Device Role / Timing Role: Bidirectional SP8T analog switch enabling source selection without relays or mechanical switches. Use Value: <0.04% THD preserves audio fidelity; <–90dB crosstalk prevents bleed between left/right or source channels. |
| Low-Voltage Industrial Sensors | Communications Circuit Protection |
Use Scenario: Isolating fault currents in 4–20mA loop-powered transmitters by switching diagnostic test points into the loop. IC Role / Device Role / Timing Role: High-impedance analog switch inserted in series with current loop; controlled via isolated digital lines. Use Value: ±8V dual-supply operation matches loop compliance voltage; 0.1nA leakage avoids disrupting 4mA minimum current. | Use Scenario: Protecting RS-232 or CAN transceiver inputs from ESD events by inserting a low-capacitance switch between connector and IC. IC Role / Device Role / Timing Role: Fail-safe analog switch that disconnects sensitive PHY during overvoltage detection. Use Value: C(ON) = 8pF minimizes signal integrity impact; break-before-make action prevents short-circuit during reconfiguration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | Higher on-resistance (12Ω typ), wider supply (±15V), SPI interface instead of parallel address | Requires MCU firmware update for serial control; better for high-voltage industrial I/O | Select when ±15V operation or SPI bus integration is required; not pin-compatible |
| TMUX1308PWR | Lower on-resistance (4.5Ω typ), single +1.8V to +5.5V supply only, no dual-supply support | Optimized for ultra-low-power battery devices; incompatible with bipolar or >5.5V systems | Select for 3.3V-only portable designs where lowest RON and power matter most |
Compared with ADG1408BRUZ and TMUX1308PWR, the MAX4051EEE+T uniquely balances dual-supply flexibility, guaranteed RON matching, and legacy 74HC4051 footprint compatibility - making it optimal for upgrading existing industrial data-acquisition boards without layout changes.

FAQ
What is the operating temperature range for the MAX4051EEE+T?
The MAX4051EEE+T is rated for –40°C to +85°C operation, as confirmed by its "EEE" suffix in the ordering code and the Electrical Characteristics tables specifying performance across this full industrial temperature range. This makes the MAX4051EEE+T suitable for deployment in outdoor sensors, factory automation controllers, and automotive cabin electronics where ambient temperatures vary widely.
Does the MAX4051EEE+T support single-supply operation?
Yes, the MAX4051EEE+T supports single-supply operation from +2.7V to +16V with V− connected to GND. At +5V, it delivers 225Ω max on-resistance and maintains 0.1nA off-leakage at +25°C. Its logic thresholds (0.8V to 2.4V) ensure compatibility with 3.3V or 5V microcontrollers without external level-shifting circuitry.
How does the MAX4051EEE+T handle analog signal directionality?
The MAX4051EEE+T supports fully bidirectional analog signal flow: NO and COM pins are functionally identical and interchangeable. Signals pass with equal integrity in either direction, and the device imposes no polarity constraints - enabling flexible use as input multiplexers, output demultiplexers, or signal crosspoints in both acquisition and stimulus paths.
What is the maximum analog signal voltage the MAX4051EEE+T can switch?
The MAX4051EEE+T switches rail-to-rail analog signals from V− to V+. With ±5V supplies, this means –5V to +5V; with +12V/V− = GND, it handles 0V to +12V. Exceeding V+ or V− forward-biases internal ESD diodes, so input signals must remain within these bounds unless external clamping is added per Figure 1 in the datasheet.
Is the MAX4051EEE+T pin-compatible with the 74HC4051?
Yes, the MAX4051EEE+T is explicitly pin-compatible with the industry-standard 74HC4051, sharing identical pinout, function mapping, and 16-pin QSOP footprint. This allows direct replacement in legacy designs to upgrade performance - including lower on-resistance (100Ω vs. ~120Ω), tighter RON matching (6Ω vs. unspecified), and reduced leakage (0.1nA vs. 1nA).
