Product details
Overview
MAX4051EEE from Maxim Integrated is an 8-channel CMOS analog multiplexer configured for rail-to-rail signal switching in low-voltage systems. It supports ±2.7V to ±8V dual supplies or +2.7V to +16V single supply, delivers 100Ω on-resistance at ±5V, guarantees 6Ω channel-to-channel on-resistance match (A-grade), and exhibits only 0.1nA off-leakage at +25°C - enabling precision signal routing in battery-powered data acquisition.
For engineers reviewing the MAX4051EEE datasheet, MAX4051EEE pinout, MAX4051EEE application, or MAX4051EEE equivalent, key selection criteria include guaranteed on-resistance flatness (<10Ω), break-before-make timing (≤75ns), TTL/CMOS logic compatibility, low crosstalk (<–90dB), and QSOP-16 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4051EEE implements a single 8:1 analog multiplexer using complementary CMOS switch architecture with independent V+, V-, and GND supply domains. Its address decoding (ADDA/ADDB/ADDC) and inhibit (INH) logic drive transmission gates that pass bidirectional analog signals across the full supply rail range without level-shifting.
All NOx/COM pins are functionally identical and interchangeable; no fixed input/output assignment exists. Internal ESD diodes clamp analog pins to V+ and V−, defining absolute voltage limits and contributing to leakage current asymmetry between supply rails - a critical factor in high-impedance sensor front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2.7V to ±8V dual or +2.7V to +16V single - enables operation from Li-ion battery (3.0V) up to industrial 15V rails |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in 600Ω audio/data paths |
| RON Match | 6Ω max (MAX4051A variant) - maintains channel-to-channel gain consistency in multi-sensor scanning |
| Off-Leakage Current | 0.1nA at +25°C - preserves accuracy in picoamp-level sensor interfaces and high-Z sample-and-hold circuits |
| Crosstalk | <–90dB at 100kHz (50Ω) - prevents signal coupling between active and inactive channels in dense routing |
| Turn-On Time | 75ns typical at ±5V - supports multiplexing rates up to ~10MHz in time-critical DAQ systems |
| Logic Thresholds | 0.8V to 2.4V - ensures reliable switching with 3.3V or 5V TTL/CMOS control without level shifters |
Pinout & Package
MAX4051EEE is supplied in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), optimized for automated assembly and thermal performance in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 (Normally Open) | Bidirectional analog switch terminals - any may serve as input or output; all electrically identical |
| 3 | COM (Common) | Central analog node connected to selected NOx channel; no internal bias or reference |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs selecting one of eight NOx paths to COM |
| 6 | INH (Inhibit) | Active-high global disable - forces all switches open regardless of address state |
| 7 | V− | Negative analog supply rail - tied to GND for single-supply operation |
| 8 | GND | Digital ground reference only - no analog signal return path |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch gates |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy designs without PCB revision |
| Rail-to-rail analog signal handling | Supports input/output voltages from V− to V+ - eliminates external clamping in ±5V systems |
| Guaranteed on-resistance flatness | ≤10Ω variation over full analog range - minimizes harmonic distortion (<0.04% @600Ω) |
| Low charge injection | 2pC typical - reduces settling error in precision sampling applications with 1nF load |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRUZ | 8:1 CMOS mux with 45Ω RON (±15V), higher supply voltage range, but 2.5nA off-leakage at +25°C | Preferred in high-voltage industrial control where leakage is less critical than voltage headroom | Select when system requires >±10V analog swing and can tolerate 25× higher off-leakage |
| TS5A23157DGSR | 2-channel SPDT with 0.9Ω RON (+3.3V), lower on-resistance but only 2:1 topology and no 3-bit addressing | Suitable for simple signal path selection, not multi-channel scanning | Choose for ultra-low RON in dual-path applications where address decoding is handled externally |
Compared with ADG408BRUZ and TS5A23157DGSR, the MAX4051EEE uniquely balances ultra-low leakage (0.1nA), precise RON matching (6Ω), and full 8:1 integration in a QSOP package - making it optimal for battery-powered, multi-sensor precision DAQ where channel consistency and power efficiency are co-critical.

FAQ
What is the maximum analog signal voltage range supported by the MAX4051EEE?
The MAX4051EEE supports rail-to-rail analog signals from V− to V+. With ±5V supplies, this means –5V to +5V; with a single +5V supply (V− = GND), the range is 0V to +5V. Absolute maximum ratings allow V+ up to +17V and V− down to –17V, but operational analog range remains bounded by the applied supply rails. The MAX4051EEE does not require external level-shifting circuitry for full-range signal handling within these bounds.
Does the MAX4051EEE require external pull-up or pull-down resistors on its address pins?
No, the MAX4051EEE does not require external pull-up or pull-down resistors on ADDA, ADDB, or ADDC pins. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (0.8V to 2.4V) and low input current (±1µA), allowing direct connection to microcontroller GPIOs or logic gates. However, in noisy environments or floating-control scenarios, a 10kΩ pull-down on INH is recommended to ensure default-off safety.
Can the MAX4051EEE be used with a single +3.3V supply?
Yes, the MAX4051EEE operates with a single +3.3V supply (V+ = +3.3V, V− = GND). At this voltage, typical on-resistance increases to ~525Ω (vs. 100Ω at ±5V), and turn-on time extends to ~600ns, but all logic thresholds and leakage specs remain valid. The device maintains rail-to-rail analog capability from 0V to +3.3V, making it suitable for low-power 3.3V microcontroller-based systems where signal fidelity requirements permit higher RON.
How does the MAX4051EEE handle signal directionality between NO and COM pins?
The MAX4051EEE has no intrinsic signal directionality: NOx and COM pins are fully interchangeable and bidirectional. Either terminal may serve as input or output, and analog signals pass with identical electrical characteristics in both directions. This symmetry simplifies PCB layout and enables flexible routing - for example, using COM as a common sensor input and NOx as individual channel outputs, or vice versa - without performance penalty.
Is the MAX4051EEE pin-compatible with the standard 74HC4051?
Yes, the MAX4051EEE is pin-compatible with the industry-standard 74HC4051 in the same QSOP-16 package. Pin assignments for V+, GND, V−, INH, ADDA–ADDC, COM, and NO0–NO7 match exactly. However, the MAX4051EEE offers superior specifications: lower on-resistance (100Ω vs. ~120Ω), tighter RON matching (6Ω vs. unspecified), and drastically lower leakage (0.1nA vs. ~100nA), making it a performance upgrade without layout changes.
