Product details
Overview
MAX4051ACEE 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 max 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 channel selection.
For engineers reviewing the MAX4051ACEE datasheet, MAX4051ACEE pinout, MAX4051ACEE application, or MAX4051ACEE equivalent, key selection criteria include guaranteed on-resistance matching (≤6Ω), low charge injection (≤10pC), high off-isolation (<−90dB), and QSOP-16 package compatibility with space-constrained mixed-signal PCB layouts.
Technical Context
The MAX4051ACEE 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 supply rails while enabling operation across wide voltage ranges.
All NOx and COM pins are bidirectional and functionally interchangeable; switching is break-before-make with 30ns typical transition time and <200ns turn-on/turn-off delay under ±5V supplies. On-resistance flatness is specified at ≤10Ω over ±3V analog input range, ensuring minimal signal distortion in precision routing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel analog multiplexer (1-of-8 selection) |
| Supply Range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - supports portable and industrial rail-flexible designs |
| On-Resistance (RON) | 100Ω max at ±5V - ensures <0.1% gain error in 10kΩ source/load impedance circuits |
| On-Resistance Match (∆RON) | 6Ω max (A-grade) - enables accurate ratiometric measurements across channels |
| Off-Leakage Current | 0.1nA max at +25°C - preserves signal integrity in high-impedance sensor front-ends |
| Off-Isolation | <−90dB at 100kHz (50Ω) - suppresses crosstalk between inactive channels |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V supply - ensures reliable TTL/CMOS interfacing without level shifters |
Pinout & Package
MAX4051ACEE is housed in a 16-pin QSOP (Quarter-Size Outline Package) with 0.65mm lead pitch, 5.0mm × 3.99mm body, and exposed pad not connected internally - suitable for automated SMT assembly and moderate-power analog routing.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 (Normally Open) | Bidirectional analog inputs; any may serve as source or sink depending on address state |
| 3 | COM (Common) | Single bidirectional analog output/input - connects to selected NOx channel |
| 9, 10, 11 | ADDA, ADDB, ADDC (Address Inputs) | 3-bit binary select lines determining which NOx connects to COM (000→NO0, 111→NO7) |
| 6 | INH (Inhibit) | Active-high global disable - forces all switches open regardless of address state |
| 7 | V− | Negative analog supply rail - tied to GND for single-supply operation |
| 8 | GND | Digital ground reference only - no analog signal reference; analog signals swing rail-to-rail between V+ and V− |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch gates |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement in legacy HC4051 designs without layout changes |
| Rail-to-rail analog signal handling | Supports full V− to V+ input/output range - eliminates external biasing in bipolar signal paths |
| Low charge injection (≤10pC) | Minimizes voltage glitch on high-impedance nodes during switching - critical for sample-and-hold accuracy |
| Guaranteed on-resistance flatness (≤10Ω) | Maintains consistent gain across analog input range - reduces harmonic distortion to <0.04% |
| High off-isolation (<−90dB) | Prevents signal bleed-through from active to inactive channels - essential for multi-sensor multiplexing |
Applications

Use Value: −90dB off-isolation at 100kHz prevents coupling between sensitive receive and high-power transmit paths. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051CPE | Same electrical specs but in 16-pin plastic DIP package; wider temperature range (0°C to +70°C vs. same); higher on-resistance (125Ω at +5V) | Preferred for through-hole prototyping or legacy DIP-based systems requiring manual assembly | Select MAX4051CPE when board real estate allows DIP footprint and cost sensitivity outweighs QSOP's SMT efficiency |
| ADG408BRUZ | 8-channel CMOS mux with 44Ω RON (±15V), −105dB off-isolation, but requires ≥±5V dual supply; no single-supply operation below +5V | Better performance in high-precision lab equipment where supply headroom permits ±15V rails | Choose ADG408BRUZ only if system already uses ±15V supplies and demands lower RON or higher isolation than MAX4051ACEE provides |
Compared with MAX4051CPE and ADG408BRUZ, the MAX4051ACEE uniquely balances ultra-low leakage (0.1nA), single-supply flexibility (+2.7V min), and QSOP-16 compactness - making it optimal for space-constrained, battery-operated instrumentation where leakage-induced offset and supply versatility are critical.

FAQ
What is the maximum supply voltage rating for MAX4051ACEE?
The MAX4051ACEE supports dual supplies from ±2.7V to ±8V (V+ to V− ≤ +17V) or single supply from +2.7V to +16V. Absolute maximum ratings specify V+ to GND ≤ +17V and V− to GND ≥ −17V. Exceeding these limits risks permanent damage due to internal ESD diode conduction.
Does MAX4051ACEE support true single-supply operation down to +2.7V?
Yes, the MAX4051ACEE is fully specified for single-supply operation from +2.7V to +16V with V− tied to GND. At +2.7V, on-resistance increases to ~280Ω (typical), and switching times lengthen, but all functions-including TTL/CMOS logic compatibility-remain operational per datasheet limits.
How does the INH pin affect switching behavior in MAX4051ACEE?
The INH (inhibit) pin is an active-high global disable: when driven high, it forces all internal switches open regardless of ADDA/ADDB/ADDC states. This provides fail-safe channel isolation during system reset or fault conditions, eliminating unintended signal paths without altering address logic.
What is the guaranteed on-resistance match between channels for MAX4051ACEE?
The MAX4051ACEE (A-grade) guarantees ∆RON ≤ 6Ω across all 8 channels at ±5V supplies and +25°C. This tight matching ensures consistent gain and minimal channel-to-channel error in ratiometric measurements, such as those used in multi-sensor bridge configurations.
Can MAX4051ACEE be used in bidirectional analog signal paths?
Yes, all NOx and COM pins on the MAX4051ACEE are fully bidirectional and electrically identical. Signals pass with equal integrity in either direction - enabling flexible use as input multiplexers, output demultiplexers, or reconfigurable analog crosspoints without polarity constraints.
