Product details
Overview
MAX4051AEEE 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 typical on-resistance at ±5V, 0.1nA max off-leakage at +25°C, and TTL/CMOS logic compatibility-used in low-voltage data-acquisition systems for precision signal routing.
For engineers reviewing the MAX4051AEEE datasheet, MAX4051AEEE pinout, MAX4051AEEE application, or MAX4051AEEE equivalent, this page delivers verified electrical specs, package mapping (16-pin QSOP), channel matching (≤6Ω), leakage performance, and real-world use context for battery-powered and audio routing designs.
Technical Context
The MAX4051AEEE implements a single 8:1 analog multiplexer using CMOS transmission-gate architecture with independent V+ and V- supply rails. Its digital control uses three address lines (ADDA, ADDB, ADDC) and an active-high INH inhibit input, enabling precise channel selection across the full analog signal range (V- to V+).
All NO/COM pins are bidirectional and interchangeable; internal ESD diodes clamp signals exceeding V+ or V-, while leakage current originates primarily from reverse-biased protection diodes-not signal path coupling. On-resistance flatness is guaranteed at ≤10Ω over ±3V signal swing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V supplies - ensures minimal signal attenuation and gain error in precision sensor or audio paths. |
| On-resistance match (∆RON) | 6Ω max between channels - enables accurate ratiometric measurements and matched gain across multiplexed inputs. |
| Off-leakage current | 0.1nA max at +25°C - preserves high-impedance node integrity in battery-operated instrumentation. |
| Supply range | ±2.7V to ±8V dual or +2.7V to +16V single - supports wide input voltage flexibility without level-shifting circuitry. |
| Logic thresholds | 0.8V to 2.4V - guarantees reliable TTL/CMOS compatibility across supply voltages including +5V and ±5V. |
| Off-isolation | <-90dB at 100kHz - suppresses crosstalk between inactive channels in multi-signal routing applications. |
| Charge injection | 2pC typical - minimizes voltage glitch on high-impedance sampling capacitors in ADC front-ends. |
Pinout & Package
MAX4051AEEE is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.15mm lead pitch and 5.0mm × 4.0mm body size, rated for -40°C to +85°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive analog/digital supply | Drives internal CMOS gates and sets upper analog signal limit; must be ≥ V- + 2.7V in dual-supply mode. |
| 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 connection-signals are fully floating between V+ and V-. |
| INH | Digital inhibit input | Active-high; forces all switches open when logic high-critical for power sequencing and fault-safe shutdown. |
| ADDA, ADDB, ADDC | Binary address inputs | Select one of eight NOx inputs to connect to COM; ADDC not used on MAX4052 variants. |
| COM | Common analog terminal | Bidirectional; connects to selected NOx pin-functions as input or output depending on system topology. |
| NO0–NO7 | Normally-open analog inputs | Eight independent analog nodes; any may serve as source or sink-no internal pull-up/down or directionality. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Drop-in replacement for legacy HC4051 designs without PCB layout changes-preserves existing footprint and routing. |
| Guaranteed RON match | ≤6Ω max mismatch between channels-enables high-accuracy multiplexing in ratiometric sensor arrays and calibration circuits. |
| Rail-to-rail analog signal range | Signals swing from V- to V+ without clipping-supports full dynamic range in ±5V op-amp interfaces and unipolar/bipolar sensor outputs. |
| Low distortion & crosstalk | <0.04% THD at 600Ω load and <-90dB crosstalk-maintains signal fidelity in audio routing and communication channel switching. |
| Single-supply operation down to +2.7V | Enables direct integration into Li-ion battery-powered systems (2.7–4.2V) without charge pumps or regulators. |
Applications
| Audio Signal Routing | Portable Data Acquisition |

Use Scenario: Isolating and routing RS-232, RS-485, and CAN transceiver signals in a modular industrial gateway with shared UART resources. IC Role / Device Role / Timing Role: Bidirectional analog switch managing signal path selection between multiple physical layer ICs and a microcontroller UART. Use Value: ±8V dual-supply capability matches RS-232 voltage levels; break-before-make timing (≤225ns) prevents bus contention during reconfiguration. | Use Scenario: Enabling low-power sleep modes in handheld multimeters by disconnecting unused sensor front-ends and reference dividers. IC Role / Device Role / Timing Role: Low-leakage analog switch isolating high-impedance divider networks and op-amp bias paths during standby. Use Value: 0.1nA off-leakage extends battery life by minimizing quiescent current in >10MΩ measurement paths; +2.7V minimum supply allows operation down to near end-of-life cell voltage. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051CEE | Same functionality but rated for 0°C to +70°C temperature range; higher RON match (12Ω vs. 6Ω); 1nA off-leakage at +25°C vs. 0.1nA. | Suitable for commercial-grade equipment where extended temperature or ultra-low leakage is not required. | Select MAX4051CEE only if cost sensitivity outweighs need for A-grade leakage and matching specs. |
| ADG1408BRUZ | 8:1 mux with 4.7Ω on-resistance, ±15V supply, but 100pA typical off-leakage (vs. 0.1nA max); requires separate logic supply; not pin-compatible. | Better for high-voltage industrial I/O modules needing wider supply range and lower RON, but demands redesign. | Choose ADG1408BRUZ only when ±15V operation or sub-5Ω RON is mandatory-and layout changes are acceptable. |
Compared with MAX4051CEE and ADG1408BRUZ, the MAX4051AEEE uniquely balances ultra-low leakage (0.1nA), tight channel matching (6Ω), and true pin compatibility with 74HC4051 footprints-making it optimal for upgrading legacy designs or deploying in battery-constrained, precision measurement systems without board revision.

FAQ
What is the maximum supply voltage range supported by the MAX4051AEEE?
The MAX4051AEEE supports dual supplies from ±2.7V to ±8V (V+ to V- differential up to 16V), or a single supply from +2.7V to +16V with V- tied to GND. Absolute maximum ratings allow V+ up to +17V and V- down to -17V, but continuous operation beyond ±8V or +16V is not specified and may compromise reliability or parametric performance.
Does the MAX4051AEEE require external level-shifting when interfacing with 3.3V microcontrollers?
No, the MAX4051AEEE does not require external level-shifting. Its ADDA, ADDB, ADDC, and INH inputs have TTL/CMOS-compatible thresholds (0.8V low, 2.4V high) that function correctly with 3.3V logic-even when powered from ±5V or +5V supplies. Input currents remain below ±1µA, eliminating loading concerns.
How does the MAX4051AEEE handle analog signals that exceed the supply rails?
The MAX4051AEEE includes internal ESD-protection diodes from each NO and COM pin to both V+ and V-. If an analog signal exceeds V+ or drops below V-, the corresponding diode conducts, clamping the voltage. This limits overvoltage but risks excessive current if not externally limited-designers must ensure signal sources cannot deliver more than ±30mA continuously or ±100mA pulsed (1ms, 10% duty cycle).
Is the MAX4051AEEE pin-compatible with the standard 74HC4051?
Yes, the MAX4051AEEE is fully pin-compatible with the industry-standard 74HC4051 in 16-pin QSOP, SO, and DIP packages. Pin functions-including V+, V-, GND, INH, ADDA–ADDC, COM, and NO0–NO7-are identical, enabling drop-in replacement without PCB modification. However, the MAX4051AEEE offers superior leakage, matching, and supply flexibility versus the HC4051.
What is the guaranteed on-resistance flatness specification for the MAX4051AEEE?
The MAX4051AEEE guarantees on-resistance flatness (RFLAT(ON)) of ≤10Ω over the full analog signal range (VCOM = ±3V with V+ = 5V, V- = -5V). This means the difference between maximum and minimum on-resistance-measured across the entire signal swing-is bounded, ensuring consistent insertion loss and minimal harmonic distortion in AC-coupled applications like audio routing.
