Product details
Overview
MAX4051EPE+ from Maxim Integrated is an 8-channel CMOS analog multiplexer configured for rail-to-rail signal switching in low-voltage systems. It supports dual supplies (±2.7V to ±8V) or single supply (+2.7V to +16V), delivers 100Ω on-resistance at ±5V, guarantees 6Ω channel-to-channel on-resistance match (A-suffix variant), and achieves 0.1nA off-leakage at +25°C - enabling precision signal routing in battery-powered data acquisition.
For engineers reviewing the MAX4051EPE+ datasheet, MAX4051EPE+ pinout, MAX4051EPE+ application, or MAX4051EPE+ equivalent, key selection criteria include guaranteed on-resistance flatness, TTL/CMOS logic compatibility at +5V, break-before-make timing, low charge injection (2pC), and -90dB off-isolation in 50Ω systems.
Technical Context
The MAX4051EPE+ implements a CMOS transmission-gate architecture with independent control of eight analog channels via three address bits (ADDA, ADDB, ADDC) and an inhibit input (INH). Its internal logic-level translators isolate digital control signals from analog supply rails (V+, V-, GND), enabling operation across wide voltage ranges without level-shifting circuitry.
All NO/COM terminals are bidirectional and functionally identical; signal flow direction is unrestricted. The device uses reverse-biased ESD diodes between each analog pin and V+/V- to clamp overvoltage, with leakage current dominated by differential diode conduction - a design feature directly tied to its sub-nA off-leakage specification at +25°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| On-resistance match (∆RON) | 6Ω max (MAX4051A) - enables accurate ratiometric measurements across channels |
| Off-leakage current | 0.1nA at +25°C - preserves high-impedance node integrity in low-power sampling circuits |
| Analog signal range | Rail-to-rail (V− to V+) - supports full dynamic range utilization without signal clipping |
| Logic thresholds | 0.8V to 2.4V - ensures reliable TTL/CMOS compatibility with +5V digital controllers |
| Off-isolation | <−90dB at 100kHz (50Ω) - prevents crosstalk between active and inactive channels |
| Charge injection | 2pC typical - minimizes voltage glitch on sampled capacitors in ADC front-ends |
Pinout & Package
MAX4051EPE+ is supplied in a 16-pin plastic DIP package (0.300" width) with through-hole mounting. Pin 1 is located at the left end of the top row when viewed from the top with the notch or dot oriented left.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1,2,4,5,12,13,14,15 | NO0–NO7 | Eight normally open analog switch terminals - interchangeable as inputs or outputs; no polarity constraint |
| 3 | COM | Common analog terminal - connects to selected NOx channel when enabled |
| 6 | INH | Digital inhibit input - logic high disables all switches; pulled low for normal operation |
| 7 | V− | Negative analog supply - tied to GND for single-supply use (+2.7V to +16V) |
| 8 | GND | Digital ground reference - separate from analog signal reference plane |
| 9,10,11 | ADDA, ADDB, ADDC | 3-bit binary address inputs - select one of eight NOx channels to connect to COM |
| 16 | V+ | Positive analog/digital supply - powers internal logic and switch gates; sets upper analog rail |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy logic-controlled mux designs without PCB changes |
| Guaranteed on-resistance flatness | 10Ω max variation over full analog signal range - maintains consistent gain across input voltage swing |
| Low distortion | <0.04% THD at 600Ω load - preserves signal fidelity in audio and instrumentation paths |
| Break-before-make timing | 30ns min (single +5V) - prevents momentary shorting between channels during address transitions |
| Single-supply operation down to +2.0V | Functional at 2V (though RON and tON degrade) - extends usability in ultra-low-power microcontroller systems |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG408BRZ | 8-channel CMOS mux; 100Ω RON at ±15V but only 125Ω at ±5V; 1nA off-leakage at +25°C | Higher RON and leakage reduce accuracy in low-voltage, low-current sensor systems | Prefer MAX4051EPE+ for ≤±5V operation requiring sub-nA leakage and tight RON matching |
| 74HC4051D | Pin-compatible logic-level mux; 120Ω RON at +4.5V; no guaranteed RON match or flatness spec; 100nA off-leakage | Lacks A-suffix precision specs - unsuitable for ratiometric or high-Z measurement applications | MAX4051EPE+ provides verified performance margins critical for production test and calibration stability |
Compared with ADG408BRZ and 74HC4051D, the MAX4051EPE+ delivers superior on-resistance matching (6Ω vs. unguaranteed), lower leakage (0.1nA vs. ≥1nA), and tighter flatness - making it the preferred choice for precision, low-power, and rail-to-rail analog multiplexing where measurement repeatability is essential.

FAQ
What is the maximum supply voltage range supported by the MAX4051EPE+?
The MAX4051EPE+ 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 relative to GND, but sustained operation beyond ±8V or +16V risks reliability degradation. For robust long-term use, stay within the specified functional ranges.
Does the MAX4051EPE+ support rail-to-rail analog signal switching?
Yes, the MAX4051EPE+ supports true rail-to-rail analog signal switching - signals from V− to V+ pass unattenuated through the enabled channel. This capability is maintained across its full supply range, including single-supply configurations where V− = GND and V+ = +3V to +16V, enabling full utilization of ADC input ranges and sensor output spans.
How does the MAX4051EPE+ differ from the standard MAX4051 (non-A) version?
The MAX4051EPE+ belongs to the 'A' variant family (MAX4051A), which is fully characterized for on-resistance match (6Ω max), on-resistance flatness, and low leakage (0.1nA at +25°C). Standard MAX4051 parts guarantee only 12Ω match and 1nA off-leakage. The EPE+ suffix denotes the 16-pin plastic DIP package with −40°C to +85°C temperature rating.
Can the MAX4051EPE+ be used with a +3.3V digital controller while operating from ±5V analog supplies?
Yes. The MAX4051EPE+ logic inputs (ADDA, ADDB, ADDC, INH) have TTL/CMOS-compatible thresholds (0.8V to 2.4V) that accept +3.3V logic levels even when powered from ±5V analog supplies. No level-shifting circuitry is required - the internal logic-level translators convert the 3.3V signals to full-rail gate drive for the analog switches.
What is the purpose of the INH pin on the MAX4051EPE+?
INH (Inhibit) is a digital input that globally disables all eight analog switches when driven high. When INH = logic high, all NOx–COM paths are opened regardless of address inputs. This allows fast, synchronous shutdown of signal routing - useful for power gating, fault isolation, or preventing signal contention during system reset. Tie INH to GND for normal address-controlled operation.
