Product details
Overview
MAX4051AESE+ from Maxim Integrated is an 8-channel CMOS analog multiplexer with rail-to-rail signal handling, ±2.7V to ±8V dual-supply or +2.7V to +16V single-supply operation, 100Ω guaranteed on-resistance at ±5V, 0.1nA max off-leakage at +25°C, and TTL/CMOS logic compatibility-used in battery-powered data-acquisition systems for sensor signal routing.
For engineers reviewing the MAX4051AESE+ datasheet, MAX4051AESE+ pinout, MAX4051AESE+ application, or MAX4051AESE+ equivalent, this page delivers verified electrical specs, package-confirmed pin functions, real-world use scenarios, and two validated alternative parts for low-voltage analog switching designs.
Technical Context
The MAX4051AESE+ 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 isolate digital control from analog supplies while enabling rail-to-rail analog signal swing between V+ and V−.
All channels share identical switch characteristics: matched on-resistance (≤6Ω), flat on-resistance (≤10Ω), low charge injection (≤10pC), and high off-isolation (<−90dB at 100kHz). It supports break-before-make switching with ≤225ns transition time and operates across −40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (1-of-8 selection) |
| Supply Range | ±2.7V to ±8V dual or +2.7V to +16V single - enables direct integration into mixed-voltage systems without level shifters |
| 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 - critical for multi-channel ratiometric measurements and calibration accuracy |
| Off-Leakage Current | 0.1nA max at +25°C - preserves high-impedance sensor node integrity and reduces offset drift |
| Logic Thresholds | 0.8V to 2.4V - guarantees reliable TTL/CMOS compatibility across supply voltages up to +16V |
| Off-Isolation | <−90dB at 100kHz - prevents crosstalk between inactive channels in audio and communication routing |
Pinout & Package
MAX4051AESE+ is housed in a 16-pin narrow SO (SOIC-N) package with 1.27mm pitch, JEDEC MS-012AC compliant, 10.2mm × 5.3mm body size, and exposed pad optional per custom order.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Normally open analog inputs - bidirectional, interchangeable with COM; support rail-to-rail signal routing |
| 3 | COM | Common analog terminal - connects to selected NOx channel; no ground reference required |
| 6 | INH | Digital inhibit input - logic high disables all switches; tied low for normal operation |
| 7 | V− | Negative analog supply - grounded for single-supply mode; sets lower analog voltage limit |
| 8 | GND | Digital ground reference - isolated from analog signal path; required for logic interface stability |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NOx channels; no internal pull-ups/downs |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch gates; sets upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy HC logic-based muxes without PCB redesign |
| Guaranteed RON match ≤6Ω | Enables accurate multi-channel gain/offset calibration in data loggers and medical front-ends |
| 0.1nA off-leakage at +25°C | Minimizes input bias current errors in high-Z pH, thermopile, or piezoelectric sensor interfaces |
| <−90dB off-isolation at 100kHz | Supports clean audio channel switching and RF-adjacent analog routing without signal bleed |
| Single-supply down to +2.7V | Allows operation from Li-ion or coin-cell sources in portable instrumentation and wearables |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1408BRUZ | Higher on-resistance (1.8Ω typical), wider supply range (±15V), higher cost, 16-TSSOP package | Better suited for high-voltage industrial test equipment; less optimal for sub-5V battery operation | Select when ±15V operation or lower RON tempco is required; not pin-compatible |
| TMUX1308PWR | Lower on-resistance (4.5Ω typical), single 1.8V–5.5V supply only, no dual-supply support, 16-TSSOP | Ideal for ultra-low-voltage IoT nodes but incompatible with bipolar analog signal ranges | Choose for 3.3V-only systems prioritizing low RON; requires layout change and logic-level revalidation |
Compared with ADG1408BRUZ and TMUX1308PWR, the MAX4051AESE+ uniquely balances dual-supply flexibility, sub-nA leakage, and proven 74HC4051 compatibility-making it optimal for mixed-signal portable instruments requiring rail-to-rail analog integrity and legacy design reuse.

FAQ
What is the operating temperature range for MAX4051AESE+?
The MAX4051AESE+ is rated for −40°C to +85°C operation, confirmed by its "E" grade suffix and ordering information table listing MAX4051AESE under −40°C to +85°C temperature range with 16-pin narrow SO packaging. This makes MAX4051AESE+ suitable for industrial environments and automotive cabin applications where extended thermal performance is required.
Does MAX4051AESE+ support single-supply operation?
Yes, MAX4051AESE+ supports single-supply operation from +2.7V to +16V with V− tied to GND. Electrical characteristics tables explicitly list "Single +5V Supply" and "Single +3V Supply" test conditions, and the Applications Information section confirms functionality down to ~+1.7V (though not guaranteed). This capability allows MAX4051AESE+ to interface directly with 3.3V or 5V microcontrollers without level translation.
What is the maximum on-resistance specification for MAX4051AESE+?
The guaranteed maximum on-resistance for MAX4051AESE+ is 100Ω when operated with ±5V supplies, as specified in the "ELECTRICAL CHARACTERISTICS-Dual Supplies" table under RON parameter (TYP = 125Ω, MAX = 100Ω at TA = +25°C, V+ = 5V, V− = −5V, INO = 1mA, VCOM = ±3V). This value is tighter than the non-A version (125Ω max), reflecting the A-suffix characterization for precision matching.
Is MAX4051AESE+ pin-compatible with standard 74HC4051 devices?
Yes, MAX4051AESE+ is explicitly pin-compatible with industry-standard 74HC4051, as stated in the Features section: "Pin Compatible with Industry-Standard 74HC4051/74HC4052/74HC4053". The pin configuration diagram for MAX4051 matches the 16-pin DIP/SO/QSOP layout of 74HC4051, including identical NO0–NO7, COM, ADDA–ADDC, INH, V+, V−, and GND assignments.
What is the off-leakage current specification for MAX4051AESE+ at +85°C?
The off-leakage current for MAX4051AESE+ is specified as 5nA maximum at +85°C, per the General Description: "The off-leakage current is only 0.1nA at +25°C or 5nA at +85°C (MAX4051A/MAX4052A/MAX4053A)". This value is confirmed in the "ELECTRICAL CHARACTERISTICS-Dual Supplies" table under INO(OFF), where the MAX4051A row lists −5nA / +5nA limits at TA = TMAX.
