Product details
Overview
MAX4051AESE+T from Maxim Integrated is an 8-channel CMOS analog multiplexer with ±5V dual-supply operation, 100Ω typical on-resistance, 6Ω guaranteed channel-to-channel on-resistance match, 0.1nA max off-leakage at +25°C, and rail-to-rail signal handling - used in low-voltage data-acquisition systems for precision analog signal routing.
For engineers reviewing the MAX4051AESE+T datasheet, MAX4051AESE+T pinout, MAX4051AESE+T application, or MAX4051AESE+T equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts for design-in flexibility under battery-powered, audio, and communications constraints.
Technical Context
The MAX4051AESE+T implements a single 8:1 analog multiplexer using complementary CMOS switch architecture with independent logic-level translators driving analog switches between V+ and V−. Its digital control uses three address bits (ADDA, ADDB, ADDC) and an active-high INH inhibit input to select one of eight NOx inputs to connect to the common COM terminal.
All analog terminals (NO0–NO7, COM) support rail-to-rail voltage swing from V− to V+, with internal ESD diodes clamping signals beyond supply rails. Logic thresholds (0.8V/2.4V) ensure TTL/CMOS compatibility across ±2.7V to ±8V dual supplies or +2.7V to +16V single supply operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (1-of-8) |
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and gain error in precision measurement paths |
| On-resistance match (∆RON) | 6Ω max - enables accurate ratiometric measurements and channel calibration without per-channel correction |
| Off-leakage current | 0.1nA max at +25°C - preserves high-impedance sensor node integrity and reduces offset drift in µA-level circuits |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports portable, industrial, and mixed-signal system power architectures |
| Logic compatibility | 0.8V to 2.4V thresholds - interoperates directly with 3.3V/5V microcontrollers and FPGAs without level-shifting |
| Off-isolation | <−90dB at 100kHz (50Ω) - prevents crosstalk-induced noise coupling between inactive channels |
Pinout & Package
MAX4051AESE+T is supplied in a 16-pin narrow SOIC (SO) package (body width 3.9mm), RoHS-compliant, with standard JEDEC MS-012AC outline and thermal pad omitted.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog inputs - bidirectional; any may serve as source or sink depending on COM connection |
| 3 | COM | Common analog terminal - connects to selected NOx channel; no ground reference; operates rail-to-rail |
| 6 | INH | Digital inhibit - high disables all switches; low enables address decoding; TTL/CMOS compatible |
| 7 | V− | Negative analog supply - tied to GND for single-supply use; sets lower analog signal limit |
| 8 | GND | Digital ground reference only - no analog return path; isolates logic from analog domains |
| 9, 10, 11 | ADDA, ADDB, ADDC | Binary address inputs - decode 000–111 to select NO0–NO7; no internal pull-ups/downs |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch drivers; sets upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy designs - same pinout, timing, and logic interface |
| Guaranteed RON flatness | 10Ω max over full analog signal range - maintains consistent gain and linearity across input voltage swing |
| Low charge injection | 2pC typical - minimizes voltage glitch on high-impedance nodes during switching, critical for sample-hold accuracy |
| Rail-to-rail analog operation | V− to V+ signal handling - eliminates external biasing for bipolar or wide-dynamic-range sensors |
| Break-before-make switching | 30ns min tOPEN at +25°C - prevents momentary shorting between channels during address transitions |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | 44Ω max RON at ±5V; 0.5pA typical off-leakage; SPI interface instead of parallel address lines | Requires microcontroller firmware integration; better leakage but less direct hardware replacement | Select when ultra-low leakage and serial control outweigh pin compatibility needs |
| 74HC4051D,653 | 120Ω max RON at ±5V; 100nA off-leakage at +25°C; no guaranteed RON match or flatness spec | Lower cost but higher distortion and mismatch - suitable for non-precision signal routing only | Select for cost-sensitive, non-critical analog switching where leakage & matching are not design constraints |
Compared with ADG1408BRUZ and 74HC4051D,653, the MAX4051AESE+T uniquely balances guaranteed 6Ω RON match, 0.1nA leakage, and pin-for-pin 74HC4051 compatibility - making it optimal for upgrade paths requiring zero layout change and validated performance in precision, low-power systems.

FAQ
What is the maximum supply voltage rating for MAX4051AESE+T?
The MAX4051AESE+T supports dual supplies from ±2.7V to ±8V (V+ to V− ≤ 17V) or single supply from +2.7V to +16V. Absolute maximum ratings specify V+ to GND ≤ +17V and V− to GND ≥ −17V. Exceeding these risks permanent damage, and proper sequencing (V+ first, then V−, then logic) is required for robust operation.
Does MAX4051AESE+T support rail-to-rail analog signal operation?
Yes, the MAX4051AESE+T supports true rail-to-rail analog signal operation from V− to V+. All NOx and COM pins handle signals across the full supply range without clipping or distortion, provided V− and V+ remain within absolute maximum ratings and ESD diodes are not forward-biased.
What is the guaranteed on-resistance match between channels for MAX4051AESE+T?
The MAX4051AESE+T guarantees a maximum on-resistance match (∆RON = RONMAX − RONMIN) of 6Ω across all eight channels when operated at ±5V supplies. This tight matching enables high-accuracy ratiometric measurements and simplifies calibration in multi-channel data acquisition systems.
Can MAX4051AESE+T operate from a single +3.3V supply?
Yes, the MAX4051AESE+T operates from a single +3.3V supply (V− = GND). At +3.3V, typical on-resistance rises to ~350Ω, and switching times increase, but logic thresholds remain compatible. For best performance, use V+ ≥ +4.5V; however, functional operation is confirmed down to +2.7V per datasheet specifications.
Is MAX4051AESE+T pin-compatible with the standard 74HC4051?
Yes, the MAX4051AESE+T is fully pin-compatible with the industry-standard 74HC4051, sharing identical pinout, logic-level compatibility, and function. It improves upon the 74HC4051 with guaranteed RON match (6Ω vs. unspecified), lower leakage (0.1nA vs. 1nA), and enhanced RON flatness - enabling direct replacement in existing designs.
