Product details
Overview
MAX4051ESE+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 thresholds-used in low-voltage data-acquisition systems for sensor channel selection.
For engineers reviewing the MAX4051ESE+T datasheet, MAX4051ESE+T pinout, MAX4051ESE+T application, or MAX4051ESE+T equivalent, this page delivers verified electrical specs, package mapping to 16-pin narrow SO, real-world use scenarios in battery-powered instrumentation, and two validated alternative parts with documented functional and parametric differences.
Technical Context
The MAX4051ESE+T implements a single 8:1 analog multiplexer using complementary MOSFET pairs per channel, driven by decoded ADDA/ADDB/ADDC address inputs and controlled by an active-low INH inhibit signal. Its internal logic-level translators isolate digital control from analog supply rails (V+, V−), enabling operation across dual supplies (±2.7V to ±8V) or single supply (+2.7V to +16V).
All NOx and COM pins are bidirectional and interchangeable; no ground reference is required for analog signals, which swing fully between V+ and V−. On-resistance flatness is guaranteed at 10Ω (MAX4051), and channel-to-channel crosstalk remains below −90dB at 100kHz into 50Ω loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | Rail-to-rail: supports full-swing signals from V− to V+ without clipping |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal voltage drop and gain error in precision signal paths |
| Off-Leakage Current | 0.1nA max at +25°C - preserves high-impedance node integrity in sample-and-hold or sensor interfaces |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V supply - guarantees reliable TTL/CMOS compatibility |
| Supply Range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - enables flexible power architecture in portable and industrial designs |
| Off-Isolation | <−90dB at 100kHz - prevents signal coupling between unselected channels in multi-channel systems |
| Charge Injection | 2pC typical - minimizes settling error in switched-capacitor circuits and ADC front-ends |
Pinout & Package
MAX4051ESE+T is housed in a 16-pin narrow SOIC (SO) package with 1.27mm pitch, JEDEC MS-012AC compliant, and rated for −40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog terminals - selectable as inputs or outputs; all electrically identical |
| 3 | COM | Common analog terminal - connects to one selected NOx channel when enabled |
| 6 | INH | Digital inhibit input - logic high disables all switches; tied low for normal operation |
| 7 | V− | Negative analog supply - grounded for single-supply use; sets lower analog voltage limit |
| 8 | GND | Digital ground reference - separate from analog signal path; no current return for analog signals |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NOx channels (000–111) |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch drivers; sets upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy HC4051 designs without PCB changes |
| Guaranteed RON match | 12Ω max difference between any two channels - critical for matched-gain multiplexing |
| Low distortion | <0.04% THD at 600Ω load - preserves signal fidelity in audio routing applications |
| Break-before-make timing | 30ns min (single +5V) - prevents momentary shorting during channel switching |
| Single-supply operation down to +2.7V | Enables integration into 3V microcontroller-based systems without level-shifting circuitry |
Applications
| Battery-Operated Instrumentation | Audio Signal Routing |
|---|---|
Use Scenario: Portable multimeter selecting among 8 sensor inputs (thermocouple, RTD, voltage, current) with auto-ranging. IC Role / Device Role / Timing Role: 8:1 analog multiplexer enabling sequential sampling under MCU control via ADDA/ADDB/ADDC. Use Value: 0.1nA off-leakage prevents measurement drift; rail-to-rail support captures full sensor output range without external biasing. | Use Scenario: Consumer AV receiver routing line-level stereo signals between 8 sources (CD, phono, Bluetooth, HDMI ARC, etc.). IC Role / Device Role / Timing Role: Bidirectional SP8T switch handling analog audio paths with <0.04% THD and <−90dB crosstalk. Use Value: Low on-resistance (100Ω) avoids insertion loss; CMOS construction eliminates DC blocking capacitors. |

IC Role / Device Role / Timing Role: High-isolation analog switch isolating receive paths during transmit bursts to prevent desensitization. Use Value: <−90dB off-isolation at 100kHz suppresses LO leakage and intermodulation; dual-supply operation supports ±5V bias schemes. |
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 only specified down to −40°C; 1nA off-leakage at +25°C (10× higher than MAX4051ESE+T) | Higher supply voltage tolerance (±15V), but less suitable for ultra-low-leakage sensor front-ends | Select when operating above ±8V or requiring extended temperature screening beyond +85°C |
| TMUX1308PWR | 8:1 mux with 1.8V–5.5V single-supply operation; 0.5nA off-leakage at +25°C; no dual-supply support | Optimized for 3.3V/1.8V logic domains; lacks bipolar supply capability and rail-to-rail analog swing | Select for modern low-voltage embedded systems where dual-supply operation is unnecessary |
Compared with ADG408BRUZ and TMUX1308PWR, the MAX4051ESE+T uniquely balances ultra-low leakage (0.1nA), dual-supply flexibility (±2.7V to ±8V), and proven 74HC4051 pin compatibility-making it optimal for upgrading legacy designs while maintaining precision in battery-constrained, wide-voltage-range applications.

FAQ
What is the maximum supply voltage range supported by the MAX4051ESE+T?
The MAX4051ESE+T operates with dual supplies from ±2.7V to ±8V or a single supply from +2.7V to +16V. Absolute maximum ratings allow V+ up to +17V and V− down to −17V, but sustained operation beyond ±8V or +16V risks reliability degradation. For robust design, stay within the recommended ranges specified in the datasheet's Electrical Characteristics tables.
Does the MAX4051ESE+T require external pull-up or pull-down resistors on its address lines?
No, the MAX4051ESE+T does not require external pull-up or pull-down resistors on ADDA, ADDB, or ADDC. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (VIL = 0.8V, VIH = 2.4V at +5V), and internal input current is limited to ±1µA. Direct connection to microcontroller GPIOs or logic gates is sufficient-provided voltage levels remain within the specified logic thresholds.
Can the MAX4051ESE+T be used with a single +3.3V supply?
Yes, the MAX4051ESE+T supports single-supply operation down to +2.7V, including +3.3V. At +3.3V, on-resistance increases to approximately 250Ω (typical), and switching times lengthen (e.g., tON ≈ 180ns), but all functionality-including rail-to-rail analog signal handling and logic compatibility-remains fully operational. Verify timing margins in your specific application.
How is analog signal directionality handled on the MAX4051ESE+T pins?
All NOx and COM pins on the MAX4051ESE+T are bidirectional and electrically identical-either can serve as input or output. Signals pass equally well in both directions, with no internal polarity or direction bias. This allows flexible PCB layout and reuse of the same device in source-selection or destination-routing configurations without redesign.
What is the thermal performance of the MAX4051ESE+T in its narrow SOIC package?
The MAX4051ESE+T in 16-pin narrow SOIC has a thermal resistance θJA of 8.70°C/W. At maximum ambient temperature (+85°C) and 696mW continuous power dissipation (derated above +70°C), junction temperature remains within safe limits. For high-density layouts, ensure adequate copper pour and airflow; derating begins at +70°C at 8.70mW/°C.
