Product details
Overview
MAX4051ACSE+T 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 low-voltage data-acquisition systems for channel selection and signal routing.
For engineers reviewing the MAX4051ACSE+T datasheet, MAX4051ACSE+T pinout, MAX4051ACSE+T application, or MAX4051ACSE+T equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases in battery-powered instrumentation, and two confirmed alternative parts with documented technical differences.
Technical Context
The MAX4051ACSE+T implements a single 8:1 analog multiplexer using CMOS transmission-gate architecture with independent digital address decoding (ADDA/ADDB/ADDC) and global inhibit (INH). Its internal logic-level translators interface TTL/CMOS inputs to analog switch gates without direct coupling between digital and analog supply domains.
It supports break-before-make switching with 30ns typical tOPEN, exhibits <−90dB off-isolation and crosstalk at 100kHz (50Ω), and maintains flat on-resistance (<10Ω variation) across its full analog signal range - critical for precision multiplexing in multi-channel sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel single-pole multiplexer (8:1) |
| Supply Range | ±2.7V to ±8V dual or +2.7V to +16V single - enables direct integration into mixed-voltage systems |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision measurement paths |
| On-Resistance Match | 6Ω max between channels (A-suffix) - preserves channel-to-channel gain consistency in ADC front-ends |
| Off-Leakage Current | 0.1nA max at +25°C - prevents DC offset drift in high-impedance sensor nodes |
| Off-Isolation | <−90dB at 100kHz (50Ω) - suppresses crosstalk between active and inactive channels |
| Logic Compatibility | 0.8V–2.4V thresholds at +5V supply - interoperates directly with standard TTL/CMOS controllers |
Pinout & Package
MAX4051ACSE+T is supplied in a 16-pin narrow SOIC (SO) package, 3.9mm width, with exposed pad not present. Pin assignments are validated per Maxim's official pin diagram (Rev 2, 10/05).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal CMOS switches and logic; sets upper analog signal limit (rail-to-rail up to V+) |
| V- | Negative analog supply | Sets lower analog signal limit; tied to GND for single-supply operation |
| GND | Digital ground reference | Reference for logic inputs only; no analog signal ground path |
| INH | Digital inhibit input | Active-high global disable - forces all switches open regardless of address state |
| ADDA, ADDB, ADDC | Binary address inputs | Select one of eight NOx inputs to connect to COM; ADDC absent on non-A variants |
| COM | Common analog terminal | Single bidirectional I/O node - connects to selected NOx channel during conduction |
| NO0–NO7 | Normally-open analog inputs | Bidirectional analog terminals; any may serve as input or output; interchangeable with NC pins |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Drop-in replacement for legacy designs - no PCB or firmware changes required |
| Guaranteed RON match (6Ω) | Ensures ≤0.5% gain mismatch across all 8 channels - critical for calibrated multi-sensor systems |
| Rail-to-rail analog signal range | Supports full-scale signals from V− to V+ - eliminates level-shifting in ±5V or +3.3V data loggers |
| Low charge injection (2pC typ) | Minimizes voltage glitch on high-Z sampling capacitors - improves ADC acquisition accuracy |
| Break-before-make timing (30ns) | Prevents momentary shorting between channels - essential for fault-tolerant power monitoring |
Applications
| Battery-Powered Data Loggers | Audio Signal Routing |
|---|---|

IC Role / Device Role / Timing Role: Analog multiplexer enabling sequential sampling with <30ns channel isolation and sub-nA leakage. Use Value: Extends battery life via ultra-low supply current (10µA) and eliminates external biasing components. |
Use Scenario: Switching between multiple microphone preamp outputs to a shared audio codec in conferencing hardware. IC Role / Device Role / Timing Role: Low-distortion (<0.04%) analog switch routing line-level signals with <−90dB crosstalk.

IC Role / Device Role / Timing Role: High-off-isolation (>90dB) analog switch disconnecting signal paths while maintaining logic control. Use Value: Prevents fault propagation between redundant links without adding mechanical relays or complex protection ICs. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051CSE+ | Non-A version: 12Ω max RON match, 1nA max off-leakage at +25°C | Lower-cost option where channel matching and leakage are less critical (e.g., non-precision industrial IO) | Select when budget constraints outweigh need for tight gain matching or ultra-low leakage |
| ADG1408BRUZ | ±15V supply capable, 4.7Ω typical RON, but requires separate logic supply (VL); no INH pin | Higher-voltage systems needing >±8V swing or lower on-resistance - not drop-in compatible | Choose for extended voltage range or lower RON; redesign required for VL routing and control logic |
Compared with MAX4051CSE+ and ADG1408BRUZ, the MAX4051ACSE+T provides superior channel matching (6Ω vs. 12Ω/4.7Ω) and lowest leakage (0.1nA), making it optimal for battery-powered precision multiplexing where long-term DC stability and minimal power loss are mandatory.

FAQ
What is the maximum supply voltage rating for MAX4051ACSE+T?
The MAX4051ACSE+T has absolute maximum ratings of V+ = −0.3V to +17V and V− = +0.3V to −17V, with V+ to V− differential limited 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.
Does MAX4051ACSE+T support single-supply operation with ground-referenced signals?
Yes, MAX4051ACSE+T supports true single-supply operation: tie V− to GND and apply V+ from +2.7V to +16V. Analog signals can swing rail-to-rail from 0V to V+, enabling direct interface with ground-referenced sensors and ADCs without level-shifting circuitry.
How does the INH pin function in MAX4051ACSE+T?
The INH (inhibit) pin on MAX4051ACSE+T is an active-high digital control that forces all internal switches into the open (off) state regardless of address inputs. When INH = logic high, COM is disconnected from all NOx terminals - useful for system-wide signal isolation during power-up or fault recovery sequences.
What is the guaranteed on-resistance flatness for MAX4051ACSE+T?
MAX4051ACSE+T guarantees on-resistance flatness of 10Ω maximum over its full analog signal range (VCOM = ±3V), defined as RON(max) − RON(min). This tight flatness ensures consistent gain and minimal THD (<0.04%) across the entire input voltage swing in audio and instrumentation applications.
Is MAX4051ACSE+T pin-compatible with industry-standard 74HC4051 devices?
Yes, MAX4051ACSE+T is explicitly pin-compatible with 74HC4051, sharing identical pinout, logic thresholds, and functional behavior. It offers enhanced performance including lower on-resistance (100Ω vs. ~120Ω), tighter channel matching (6Ω vs. unspecified), and lower leakage - enabling direct upgrade without layout changes.
