Product details
Overview
MAX4051CEE+ 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 enables flexible signal routing in low-voltage data-acquisition systems and battery-powered instrumentation.
For engineers reviewing the MAX4051CEE+ datasheet, MAX4051CEE+ pinout, MAX4051CEE+ application, or MAX4051CEE+ equivalent, key selection criteria include guaranteed on-resistance matching (6Ω), dual-supply operation (±2.7V to ±8V), single-supply support (+2.7V to +16V), low crosstalk (< -90dB), and QSOP-16 package compatibility.
Technical Context
The MAX4051CEE+ implements a CMOS transmission-gate architecture with independent V+ and V− supply rails, enabling true rail-to-rail analog signal switching across ±8V differential or +16V single-supply operation. Its digital control uses ADDA/ADDB/ADDC address lines and INH inhibit input, supporting full 3-bit decoding for channel selection.
Internal ESD protection diodes clamp signals exceeding V+ or V−, while logic-level translators isolate digital inputs from analog supplies. The device guarantees break-before-make timing (≤200ns), charge injection ≤10pC, and flat on-resistance (≤10Ω variation) over its specified analog input range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and voltage drop in precision analog paths |
| On-Resistance Match (∆RON) | 6Ω max (A-suffix) - enables high-accuracy channel-to-channel gain matching in multiplexed sensor interfaces |
| Off-Leakage Current | 0.1nA max at +25°C - preserves signal integrity in high-impedance, low-current applications like pH sensors |
| Supply Range | ±2.7V to ±8V dual or +2.7V to +16V single - supports wide-range portable and industrial power architectures |
| Crosstalk | < -90dB at 100kHz - prevents interference between active and inactive channels in multi-signal routing |
| Off-Isolation | < -90dB at 100kHz - maintains signal separation in sensitive measurement front-ends |
| Logic Thresholds | 0.8V to 2.4V - ensures reliable TTL/CMOS compatibility without level-shifting circuitry |
Pinout & Package
The MAX4051CEE+ is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.65mm pitch), optimized for space-constrained PCB layouts while maintaining thermal and electrical performance comparable to SOIC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog switch terminals - bidirectional signal paths selectable via address inputs |
| 3 | COM | Common analog terminal - connects to one selected NOx channel during conduction |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - determine which of eight NOx channels connects to COM |
| 6 | INH | Digital inhibit input - high logic disables all switches, overriding address decoding |
| 7 | V− | Negative analog supply - sets lower rail limit for analog signal swing; tied to GND for single-supply use |
| 8 | GND | Digital ground reference - separate from analog signal path; no direct connection to COM/NO pins |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch drivers; defines upper analog rail |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy designs without layout changes or firmware updates |
| Guaranteed RON flatness | ≤10Ω variation over full analog signal range - minimizes distortion in audio and sensor signal chains |
| Rail-to-rail analog operation | Supports signals from V− to V+ - eliminates need for external biasing in bipolar or single-supply systems |
| Low charge injection | ≤10pC - reduces settling error and glitch energy in sample-and-hold and ADC front-end circuits |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V supply - interoperates with microcontrollers and FPGAs without interface logic |

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-channel CMOS mux; 100Ω RON at ±15V, but higher 1nA off-leakage at +25°C | Less suitable for ultra-low-current sensor front-ends requiring sub-100pA leakage | Prefer MAX4051CEE+ when leakage-critical; ADG408BRUZ acceptable where higher supply voltage margin is needed |
| 74HC4051D | Pin-compatible logic-level mux; 120Ω RON at +5V, no guaranteed RON match or A-suffix leakage specs | Lacks guaranteed matching and low-leakage performance for precision measurement | MAX4051CEE+ preferred for metrology-grade designs; 74HC4051D viable for cost-sensitive, non-critical routing |
Compared with ADG4051BRUZ and 74HC4051D, the MAX4051CEE+ delivers tighter on-resistance matching (6Ω vs. unguaranteed), lower off-leakage (0.1nA vs. 1nA), and validated performance across extended supply ranges - making it optimal for precision, low-power, and battery-operated applications.

FAQ
What is the maximum supply voltage rating for the MAX4051CEE+?
The MAX4051CEE+ supports dual supplies from ±2.7V to ±8V (V+ to V− ≤ 17V) or single supplies from +2.7V to +16V. Absolute maximum ratings specify V+ up to +17V and V− down to −17V relative to GND, but continuous operation must stay within the recommended ranges to ensure reliability and guaranteed specifications. Exceeding these limits risks permanent damage.
Does the MAX4051CEE+ support rail-to-rail analog signal switching?
Yes, the MAX4051CEE+ supports true rail-to-rail analog signal switching - signals can swing from V− to V+ without clipping or distortion. This capability is enabled by its CMOS transmission-gate architecture and independent analog supply rails. When V− = 0V (single-supply mode), the analog input range extends from 0V to V+, preserving full dynamic range in 3.3V or 5V systems.
What is the guaranteed on-resistance match between channels for the MAX4051CEE+?
The MAX4051CEE+ is an A-suffix variant, guaranteeing a maximum on-resistance match (∆RON) of 6Ω between any two channels at +25°C and ±5V supplies. This tight matching is critical for applications requiring consistent gain or offset across multiplexed channels, such as multi-sensor data acquisition or calibrated test equipment.
Can the MAX4051CEE+ operate from a +3.3V single supply?
Yes, the MAX4051CEE+ operates from a +3.3V single supply (V+ = +3.3V, V− = GND). At this voltage, typical on-resistance increases to ~250Ω (max 700Ω), and switching times lengthen, but all logic thresholds and leakage specs remain valid. It is widely used in 3.3V embedded systems where low quiescent current and rail-to-rail operation are essential.
Is the MAX4051CEE+ pin-compatible with the industry-standard 74HC4051?
Yes, the MAX4051CEE+ is fully pin-compatible with the 74HC4051 in the same QSOP-16 package. Pin functions, numbering, and physical layout match exactly - enabling direct substitution without PCB modification. However, the MAX4051CEE+ adds superior specifications including guaranteed RON matching, lower leakage, and wider supply range.
