Product details
Overview
MAX4051CEE+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, 0.1nA max off-leakage at +25°C, and TTL/CMOS-compatible logic inputs. It operates from dual supplies (±2.7V to ±8V) or single supply (+2.7V to +16V), serving in low-voltage data-acquisition systems requiring precise analog signal routing.
For engineers reviewing the MAX4051CEE+T datasheet, MAX4051CEE+T pinout, MAX4051CEE+T application, or MAX4051CEE+T equivalent, key selection criteria include guaranteed on-resistance match (6Ω for A-suffix), low charge injection (2pC), high off-isolation (<–90dB), and compatibility with 74HC4051 pinout for drop-in replacement in battery-powered instrumentation and audio routing designs.
Technical Context
The MAX4051CEE+T implements a CMOS transmission-gate architecture with independent V+ and V− analog supply rails, enabling true rail-to-rail analog signal switching across ±8V or +16V ranges. Its internal logic-level translators isolate digital control signals from analog paths while maintaining TTL/CMOS thresholds (0.8V to 2.4V) across supply voltages.
It features break-before-make switching with 30ns typical delay, low distortion (<0.04% at 600Ω), and channel crosstalk <–90dB at 100kHz. The device uses substrate-connected-to-V+ construction and includes ESD-protection diodes on all analog pins referenced to V+ and V−.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (SP8T), single COM, eight NO terminals |
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and voltage drop in precision sensing paths |
| On-resistance match | 6Ω max (MAX4051A series) - enables accurate gain-matching across channels in multi-input ADC front-ends |
| Off-leakage current | 0.1nA max at +25°C - preserves signal integrity in high-impedance sensor interfaces and sample-hold circuits |
| Supply range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - supports operation from Li-ion batteries to industrial 12V rails |
| Logic compatibility | 0.8V to 2.4V input thresholds - interoperates directly with 3.3V/5V microcontrollers without level shifters |
| Off-isolation | <–90dB at 100kHz (50Ω) - prevents signal coupling between inactive channels in dense routing applications |
Pinout & Package
MAX4051CEE+T is supplied in a 16-pin QSOP package (5.3mm × 10.0mm, 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) | Eight independent analog switch inputs; bidirectional, interchangeable with COM |
| 3 | COM (Common) | Analog common node - connects to selected NO channel; no ground reference required |
| 6 | INH (Inhibit) | Active-high global disable - pulls all switches open when logic high, enabling system-wide signal isolation |
| 7 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower analog voltage limit |
| 8 | GND | Digital ground reference only - no analog return path; analog signals float between V+ and V− |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NO channels (ADDC not used in MAX4051) |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch gates; sets upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct PCB replacement in legacy designs without layout changes or firmware updates |
| Rail-to-rail analog signal handling | Supports full V− to V+ swing - eliminates clipping in ±5V op-amp stages and unipolar 0–5V sensor outputs |
| Guaranteed on-resistance flatness | 10Ω max variation over signal range - maintains consistent gain and linearity across input voltage span |
| Low charge injection | 2pC typical - minimizes voltage glitch on sampled capacitors in precision data acquisition |
| High off-isolation & low crosstalk | <–90dB at 100kHz - critical for simultaneous multi-channel sampling without inter-channel interference |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| 74HC4051D,653 | Higher on-resistance (120Ω typ at 5V), no A-suffix characterization for RON match or leakage | Limited to 5V-only operation; unsuitable for ±5V or low-leakage precision designs | Select when cost sensitivity outweighs leakage and matching requirements in non-critical routing |
| ADG1408YRUZ | Lower on-resistance (4.7Ω typ), but requires ≥±4.5V dual supply or ≥9V single supply; higher supply current | Better performance in high-speed, low-RON applications; incompatible with sub-3V battery operation | Select when ultra-low on-resistance and bandwidth (>180MHz) are mandatory, and supply headroom permits |
Compared with 74HC4051D,653 and ADG1408YRUZ, the MAX4051CEE+T uniquely balances ultra-low leakage (0.1nA), tight RON matching (6Ω), and wide supply flexibility (±2.7V to ±8V or +2.7V to +16V), making it optimal for portable, precision, and mixed-supply analog systems where signal integrity and power efficiency are co-prioritized.

FAQ
What is the maximum supply voltage rating for MAX4051CEE+T?
The MAX4051CEE+T has absolute maximum ratings of V+ = –0.3V to +17V and V– = +0.3V to –17V, with V+ to V– differential up to +17V. For reliable operation, use dual supplies within ±2.7V to ±8V or single supply from +2.7V to +16V. Exceeding these ranges risks permanent damage due to ESD diode conduction or latch-up.
Does MAX4051CEE+T support rail-to-rail analog signal switching?
Yes, the MAX4051CEE+T supports true rail-to-rail analog signal switching - signals can swing from V– to V+ without clipping. This is enabled by its CMOS transmission-gate design and independent V+ and V– supply pins. When V– = 0V (single supply), analog inputs may extend to ground; with dual supplies, signals operate fully within the negative and positive rails.
What is the function of the INH pin on MAX4051CEE+T?
INH (pin 6) is the active-high inhibit input. When driven logic high, it forces all internal switches into the open (off) state regardless of address inputs, providing global signal isolation. When pulled low or grounded, normal address-controlled switching resumes. This feature enables fast system-level shutdown or safety interlocks in fault conditions.
Is MAX4051CEE+T pin-compatible with the industry-standard 74HC4051?
Yes, MAX4051CEE+T is pin-compatible with the 74HC4051 in 16-pin DIP, SO, and QSOP packages. Pin functions (COM, NO0–NO7, ADDA–ADDC, INH, V+, V–, GND) align identically. However, MAX4051CEE+T offers superior specs: lower on-resistance (100Ω vs. 120Ω), tighter RON matching (6Ω vs. uncharacterized), and guaranteed 0.1nA off-leakage - enabling direct drop-in upgrades.
What temperature range does the MAX4051CEE+T operate across?
The MAX4051CEE+T is specified for operation from 0°C to +70°C, as indicated by the "C" grade suffix and "CEE" package code (16-pin QSOP). It is not rated for extended industrial (–40°C to +85°C) or automotive temperature ranges; for those, consider MAX4051EEE or MAX4051AESE variants instead.
