Product details
Overview
MAX4051AESE from Maxim Integrated is an 8-channel CMOS analog multiplexer with ±2.7V to ±8V dual-supply or +2.7V to +16V single-supply operation, 100Ω max on-resistance at ±5V, 6Ω guaranteed channel-to-channel on-resistance match, and 0.1nA max off-leakage at +25°C - used in low-voltage data-acquisition systems for precision signal routing.
For engineers reviewing the MAX4051AESE datasheet, MAX4051AESE pinout, MAX4051AESE application, or MAX4051AESE equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts with documented technical and application differences.
Technical Context
The MAX4051AESE implements a single 8:1 analog multiplexer using CMOS transmission-gate architecture, controlled by three binary address inputs (ADDA, ADDB, ADDC) and an active-high inhibit (INH). Its rail-to-rail analog switching supports bidirectional signal flow between COM and any of eight NOx terminals.
It guarantees matched on-resistance flatness (≤10Ω) and ultra-low leakage (0.1nA off, 0.1nA on at +25°C), enabling high-accuracy multiplexing in battery-powered instrumentation where offset drift and charge injection must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (1 × 8:1) |
| Supply Range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - enables direct interface with Li-ion, ±5V, and industrial 12V rails |
| Max On-Resistance | 100Ω at ±5V - ensures <0.1% gain error in 10kΩ sensor interfaces |
| On-Resistance Match | 6Ω max (MAX4051A series) - critical for ratiometric measurements across channels |
| Off-Leakage Current | 0.1nA at +25°C - preserves integrity of picoamp-level sensor signals |
| Logic Compatibility | TTL/CMOS thresholds (0.8V–2.4V) with ±5V or +5V supply - eliminates level-shifting in mixed-signal control |
| Off-Isolation | <−90dB at 100kHz (50Ω) - suppresses crosstalk between inactive channels |
Pinout & Package
MAX4051AESE is supplied in a 16-pin narrow SO (Small Outline) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.2mm × 5.3mm body size, and exposed pad not present.
| Pin | 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 rail-to-rail signal routing |
| 3 | COM | Common analog terminal - connects to selected NOx channel when enabled; bidirectional path |
| 6 | INH | Digital inhibit input - logic high disables all switches; tied low for normal operation |
| 7 | V− | Negative analog supply - grounded for single-supply use; sets lower analog voltage limit |
| 8 | GND | Digital ground reference - isolated from analog signal path; no current return for analog signals |
| 9,10,11 | ADDA, ADDB, ADDC | Binary address inputs - select one of eight NOx channels (000–111); TTL/CMOS compatible |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch drivers; sets upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Drop-in replacement for legacy designs without PCB changes - same pinout and logic behavior |
| Guaranteed 6Ω RON match | Enables accurate multi-channel ratiometric sensing (e.g., RTD or thermocouple scanning) without per-channel calibration |
| 0.1nA off-leakage at +25°C | Preserves signal integrity in high-impedance pH, ion-selective, or piezoelectric sensor front-ends |
| Rail-to-rail analog signal range | Supports full-scale input from V− to V+ - eliminates external biasing in bipolar signal chains |
| <−90dB off-isolation at 100kHz | Prevents interference between adjacent channels in multi-signal acquisition (e.g., medical ECG lead selection) |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | 44V max supply, 4.7Ω RON, 1pA off-leakage, TSSOP-16 package | Higher voltage rating and lower leakage suit high-precision lab equipment; higher cost and larger footprint | Select when >±15V operation or sub-picoamp leakage is required; not pin-compatible |
| TMUX1308PWR | +1.8V to +5.5V supply only, 5.5Ω RON, 10pA off-leakage, 16-TSSOP | Optimized for ultra-low-voltage IoT sensors; incompatible with ±5V or >5.5V supplies | Select for battery-critical sub-2V systems; requires layout change due to different pinout |
Compared with ADG1408BRUZ and TMUX1308PWR, the MAX4051AESE uniquely balances wide supply flexibility (±2.7V to ±8V / +2.7V to +16V), industry-standard 74HC4051 pin compatibility, and 0.1nA leakage - making it optimal for cost-sensitive, mixed-supply industrial and portable instrumentation where drop-in upgradeability matters.

FAQ
What is the operating temperature range for the MAX4051AESE?
The MAX4051AESE is rated for −40°C to +85°C operation, validated across its full electrical specification range. This extended industrial temperature grade makes it suitable for deployment in outdoor environmental sensors, factory-floor controllers, and automotive cabin electronics where thermal stability is essential. The "E" suffix in the part number explicitly denotes this −40°C to +85°C range.
Does the MAX4051AESE support single-supply operation?
Yes, the MAX4051AESE supports true single-supply operation from +2.7V to +16V with V− tied to GND. In this configuration, analog signals swing from 0V to V+, maintaining rail-to-rail capability. The device retains its 100Ω max on-resistance and 0.1nA off-leakage specifications under +5V and +12V single-supply conditions, as confirmed in the Electrical Characteristics tables.
Is the MAX4051AESE pin-compatible with the standard 74HC4051?
Yes, the MAX4051AESE is fully pin-compatible with the industry-standard 74HC4051 multiplexer. Pin assignments for V+, GND, INH, ADDA–ADDC, COM, and NO0–NO7 match exactly, enabling direct replacement in existing PCB layouts without modification. Logic thresholds (0.8V–2.4V) and timing parameters (tON/tOFF) are also aligned for functional interoperability.
What is the maximum analog signal voltage the MAX4051AESE can handle?
The MAX4051AESE supports 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. Absolute maximum ratings allow V+ up to +17V and V− down to −17V, but sustained analog signals must remain within the supply rails to avoid forward-biasing internal ESD diodes and causing leakage or damage.
How does the MAX4051AESE minimize charge injection in precision sampling circuits?
The MAX4051AESE limits charge injection to 2pC typical (10pC max) at V+ = +5V/V− = −5V, measured with CL = 1nF and RS = 0Ω. This low value - combined with its 6Ω RON match and 0.1nA leakage - reduces voltage glitches at the ADC input during channel switching, preserving accuracy in high-resolution (≥16-bit) data acquisition systems where settling time and offset stability are critical.
