Product details
Overview
MAX4051ESE 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, ±5V dual-supply or +5V single-supply operation, 100Ω typical on-resistance, <0.04% THD at 600Ω, and 0.1nA max off-leakage at +25°C. It serves in low-voltage data-acquisition systems for channel selection between sensors and ADCs.
For engineers reviewing the MAX4051ESE datasheet, MAX4051ESE pinout, MAX4051ESE application, or MAX4051ESE equivalent, key selection criteria include guaranteed on-resistance match (6Ω for A-suffix), break-before-make timing (≤75ns), off-isolation (<–90dB at 100kHz), and compatibility with TTL/CMOS logic levels across supply ranges.
Technical Context
The MAX4051ESE implements a CMOS transmission-gate architecture with independent V+ and V− supplies defining analog signal swing limits (±2.7V to ±8V or +2.7V to +16V). Its digital control uses ADDA/ADDB/ADDC address inputs and INH enable, supporting 8:1 switching via 3-bit binary decoding.
All NOx and COM pins are bidirectional and functionally interchangeable; internal ESD diodes clamp signals exceeding V+ or V−, while leakage currents originate primarily from reverse-biased protection diodes-not the switch channel itself-enabling predictable low-leakage behavior over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | Dual: ±2.7V to ±8V; Single: +2.7V to +16V - supports battery-powered and industrial rails without level-shifting. |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal voltage drop and gain error in precision signal paths. |
| On-Resistance Match | 6Ω max (MAX4051A variant) - critical for matched gain/attenuation across channels in instrumentation. |
| Off-Leakage Current | 0.1nA max at +25°C - preserves high-impedance sensor node integrity in low-power DAQ. |
| Off-Isolation | <–90dB at 100kHz (50Ω) - suppresses crosstalk between inactive channels in dense routing. |
| THD | <0.04% at 1kHz, 600Ω load - maintains fidelity in audio and precision analog signal routing. |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V supply - ensures robust TTL/CMOS compatibility without external translators. |
Pinout & Package
MAX4051ESE is supplied in a 16-pin narrow SO (Small Outline) package with 1.27mm pitch, JEDEC MS-012AC compliant, body size 10.2mm × 5.3mm × 1.75mm.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 (Normally Open) | Bidirectional analog switch terminals; any may serve as input or output; selected by ADDA/ADDB/ADDC. |
| 3 | COM (Common) | Shared analog port connected to one NOx channel per address; no ground reference required. |
| 6 | INH (Inhibit) | Active-high enable: logic high forces all switches open - enables global channel disable without address change. |
| 7 | V− | Negative analog supply; tied to GND for single-supply operation; sets lower analog signal limit. |
| 8 | GND | Digital ground reference only; analog signals float between V+ and V− with no GND path. |
| 9, 10, 11 | ADDA, ADDB, ADDC | 3-bit binary address inputs selecting one of eight NOx channels to connect to COM. |
| 16 | V+ | Positive analog/digital supply; defines upper analog signal limit and powers internal logic translators. |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Drop-in replacement for legacy HC logic without PCB redesign or layout changes. |
| Rail-to-rail analog signal handling | Supports full V− to V+ range - eliminates clipping in ±5V or +3.3V systems with bipolar signals. |
| Guaranteed low charge injection (2pC typ) | Minimizes voltage glitch on high-impedance nodes during switching - critical for sample-and-hold accuracy. |
| Break-before-make timing (≤75ns) | Prevents momentary shorting between channels - essential for safe multiplexing of conflicting sources. |
| Low crosstalk (<–90dB) | Enables simultaneous routing of sensitive and noisy signals on same board without filtering overhead. |

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; 44Ω RON at ±15V, but only specified down to ±5V; 1nA off-leakage at +25°C (10× higher than MAX4051ESE). | Higher RON and leakage limit use in ultra-low-power or high-precision DAQ where MAX4051ESE excels. | Select when wider supply range (±15V) is required and leakage tolerance >1nA is acceptable. |
| TMUX1308PWR | 8-channel mux with 1.8V–5.5V single-supply operation only; 65Ω RON at 3.3V; 0.5nA off-leakage; no dual-supply support. | Not suitable for ±5V or rail-to-rail bipolar signal routing; optimized for low-voltage digital systems. | Choose for cost-sensitive, single-supply 3.3V designs where dual-supply capability is unnecessary. |
Compared with ADG408BRUZ and TMUX1308PWR, the MAX4051ESE uniquely combines guaranteed low leakage (0.1nA), dual-supply flexibility (±2.7V to ±8V), and pin compatibility with 74HC4051-making it optimal for precision, battery-operated, or mixed-signal industrial DAQ where signal integrity and supply versatility are critical.

FAQ
What supply configurations does the MAX4051ESE support?
The MAX4051ESE operates with dual supplies from ±2.7V to ±8V or a single supply from +2.7V to +16V. When using single-supply mode, V− must be connected to GND. The device maintains rail-to-rail analog signal handling across all supported supply ranges, and its logic thresholds (0.8V/2.4V) remain TTL/CMOS-compatible at +5V. MAX4051ESE is not rated for operation below +2.7V.
How does the MAX4051ESE handle analog signal directionality?
The MAX4051ESE has fully bidirectional analog paths: NO0–NO7 and COM pins are electrically identical and interchangeable. Signals pass with equal performance in either direction-no distinction between input and output. This allows flexible system design, such as using COM as a common sensor input and NOx as selectable ADC inputs, or vice versa. MAX4051ESE requires no polarity assumptions in layout or firmware.
What is the guaranteed on-resistance match specification for MAX4051ESE?
The MAX4051ESE is part of the non-A-suffix family, with guaranteed on-resistance match of 12Ω (max) between channels at +25°C and ±5V supplies. This is distinct from the MAX4051AESE (A-suffix), which guarantees 6Ω match. The 12Ω value reflects worst-case RON variation across all eight channels-critical for applications requiring consistent gain or attenuation across multiplexed paths.
Can the MAX4051ESE be used in a +3.3V single-supply system?
Yes, the MAX4051ESE supports +3.3V single-supply operation (within its +2.7V to +16V range). At +3.3V, typical on-resistance rises to ~250Ω, and switching times increase moderately-but functionality remains fully specified. Logic thresholds scale accordingly (VIH ≈ 1.9V), remaining compatible with standard 3.3V CMOS outputs. MAX4051ESE maintains 0.1nA off-leakage and <–90dB off-isolation even at +3.3V.
Does the MAX4051ESE require external protection diodes for overvoltage?
No-MAX4051ESE integrates ESD-protection diodes from each NO and COM pin to V+ and V−. However, if analog signals may exceed V+ or fall below V− during power-up/down or fault conditions, external series diodes (as shown in Figure 1 of the datasheet) are recommended to prevent forward conduction and potential latch-up. MAX4051ESE's absolute maximum ratings must never be violated; proper supply sequencing (V+ first, then V−, then logic) is preferred over relying solely on internal protection.
