Product details
Overview
MAX4051ACSE+ 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 typical on-resistance at ±5V, 0.1nA max off-leakage at +25°C, and rail-to-rail signal handling - used in battery-powered data-acquisition systems for sensor channel selection.
For engineers reviewing the MAX4051ACSE+ datasheet, MAX4051ACSE+ pinout, MAX4051ACSE+ application, or MAX4051ACSE+ equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use scenarios, and two confirmed alternative parts for low-leakage, low-RON analog switching in precision instrumentation and portable audio routing.
Technical Context
The MAX4051ACSE+ implements a single 8:1 analog multiplexer using complementary MOSFET switches controlled by three binary address inputs (ADDA, ADDB, ADDC) and an active-low inhibit (INH). Its architecture guarantees matched on-resistance (≤6Ω between channels) and flat on-resistance (≤10Ω variation over signal range), critical for minimizing gain error in multi-channel ADC front-ends.
All digital inputs feature TTL/CMOS-compatible thresholds (0.8V to 2.4V) across supply voltages, enabling direct interfacing with microcontrollers operating at +3.3V or +5V logic levels without level-shifting - while internal ESD diodes clamp analog pins to V+ and V−, requiring proper supply sequencing to avoid latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal voltage drop and gain error in 12-bit+ precision signal paths |
| On-resistance match | 6Ω max between channels - maintains consistent channel-to-channel gain in multi-sensor systems |
| Off-leakage current | 0.1nA max at +25°C - preserves accuracy in high-impedance sensor interfaces (e.g., pH electrodes) |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports both bipolar op-amp stages and single-supply portable designs |
| Logic compatibility | 0.8V to 2.4V input thresholds - interoperates directly with 3.3V and 5V microcontrollers without translation |
| Off-isolation | <–90dB at 100kHz - suppresses crosstalk between inactive channels in dense analog routing |
| Charge injection | 2pC typical - limits settling error in sample-and-hold circuits with ≤1nF hold capacitors |
Pinout & Package
MAX4051ACSE+ is housed in a 16-pin narrow SO (Small Outline) package, 3.9mm width, with standard 1.27mm pitch and gull-wing leads - compatible with automated SMT assembly and IPC Class 2/3 reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Eight normally open analog switch terminals - bidirectional, interchangeable as inputs or outputs |
| 3 | COM | Common analog terminal - connects to selected NOx channel; no ground reference required |
| 9, 10, 11 | ADDA, ADDB, ADDC | Binary address inputs - select one of eight NOx paths (000–111); ADDC not used on MAX4052 |
| 6 | INH | Inhibit input - active-high logic disables all switches; default low enables normal operation |
| 7 | V− | Negative analog supply - tied to GND for single-supply mode; sets lower analog signal limit |
| 8 | GND | Digital ground reference - separate from analog signal path; no current return path for analog signals |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch drivers; defines upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Drop-in replacement for legacy logic-controlled muxes without PCB redesign |
| Guaranteed RON flatness | ≤10Ω variation over full analog signal range - minimizes distortion in audio and video routing |
| Rail-to-rail analog operation | Signals swing from V− to V+ - supports full dynamic range of ±5V op-amps and single-supply 0–3.3V sensors |
| Low crosstalk | <–90dB at 100kHz - prevents interference between adjacent channels in multi-tone communication circuits |
| TTL/CMOS logic interface | 0.8V/2.4V thresholds work across +3.3V and +5V MCU I/O - eliminates external level shifters |

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 mux with 45Ω RON, but only specified for +3V to +16V single supply - no guaranteed dual-supply operation below ±4.5V | Preferred where ultra-low RON is critical and bipolar supplies are not required | Select when optimizing for on-resistance in single-supply industrial sensors, not for ±5V mixed-signal systems |
| TMUX1308PWR | 8-channel mux with 1.9Ω RON, but 100nA off-leakage at +25°C - 1000× higher than MAX4051ACSE+ | Suitable for consumer audio where leakage is non-critical, but not for precision electrochemical sensing | Choose for cost-sensitive, high-speed routing where leakage tolerance exceeds 1nA |
Compared with ADG408BRUZ and TMUX1308PWR, the MAX4051ACSE+ uniquely balances low leakage (0.1nA), matched RON (6Ω), and guaranteed dual-supply operation - making it optimal for battery-powered instrumentation requiring long-term DC accuracy and rail-to-rail signal fidelity.

FAQ
What is the maximum allowable supply voltage for MAX4051ACSE+?
The MAX4051ACSE+ 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+ up to +17V and V− down to –17V relative to GND, but continuous operation beyond ±8V or +16V risks permanent damage. Always observe proper power sequencing: apply V+ first, then V−, then logic signals.
Does MAX4051ACSE+ support rail-to-rail analog signal switching?
Yes, the MAX4051ACSE+ supports true rail-to-rail analog signal operation - signals can swing from V− to V+ without clipping or increased distortion. This is enabled by its CMOS switch architecture and internal level translators, allowing full utilization of ±5V op-amp stages or 0–3.3V sensor outputs without external biasing.
What is the guaranteed on-resistance match specification for MAX4051ACSE+?
The MAX4051ACSE+ guarantees on-resistance match of ≤6Ω between any two channels (ΔRON = RON(MAX) − RON(MIN)) at +25°C with ±5V supplies. This tight matching ensures consistent gain and minimal channel-to-channel error in multi-sensor data acquisition systems, unlike the non-A version (MAX4051) which specifies ≤12Ω.
Can MAX4051ACSE+ operate from a +3.3V single supply?
Yes, the MAX4051ACSE+ operates from +2.7V to +16V single supply. At +3.3V, typical on-resistance rises to ~350Ω (vs. 100Ω at ±5V), and switching times increase - but logic thresholds remain compatible (0.8V/2.4V), enabling direct connection to 3.3V microcontrollers. Full specifications are validated down to +3.0V per the datasheet's single +3V supply table.
Is MAX4051ACSE+ pin-compatible with the standard 74HC4051?
Yes, the MAX4051ACSE+ is explicitly pin-compatible with the industry-standard 74HC4051, sharing identical pinout, function mapping, and logic-level compatibility. This allows direct substitution in existing designs to upgrade leakage performance (0.1nA vs. ~100nA), on-resistance flatness, and dual-supply capability - without layout changes or firmware modifications.
