Product details
Overview
MAX4051CSE-T from Maxim Integrated is an 8-channel CMOS analog multiplexer configured for rail-to-rail signal switching in low-voltage systems. It operates from single supplies (+2.7V to +16V) or dual supplies (±2.7V to ±8V), delivers guaranteed 100Ω on-resistance at ±5V, 0.1nA off-leakage at +25°C (A-suffix variant), and supports TTL/CMOS logic compatibility. It is used in battery-operated data-acquisition systems requiring precise analog channel selection.
For engineers reviewing the MAX4051CSE-T datasheet, MAX4051CSE-T pinout, MAX4051CSE-T application, or MAX4051CSE-T equivalent, key selection criteria include on-resistance matching (6Ω max between channels), break-before-make timing (≤75ns), off-isolation (<–90dB at 100kHz), charge injection (≤10pC), and QSOP-16 package compatibility with space-constrained PCB layouts.
Technical Context
The MAX4051CSE-T implements a CMOS transmission-gate architecture with independent control of eight normally-open analog paths via three binary address lines (ADDA, ADDB, ADDC) and an active-low inhibit input (INH). Its internal logic-level translators isolate digital control signals from analog supply domains (V+, V−, GND), enabling operation across wide voltage ranges without level-shifting circuitry.
All NOx and COM pins are bidirectional and functionally identical; signal routing direction is unrestricted. The device guarantees monotonic on-resistance flatness (≤10Ω over ±3V signal range) and maintains low crosstalk (<–90dB) and high off-isolation (<–90dB) in 50Ω systems up to 100kHz - critical for precision multiplexing in sensor front-ends and audio routing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2.7V to +16V single supply or ±2.7V to ±8V dual supply - enables direct integration into 3.3V, 5V, and ±5V systems without regulators |
| On-Resistance (RON) | 100Ω max at ±5V - ensures minimal signal attenuation and gain error in precision instrumentation paths |
| On-Resistance Match | 6Ω max between channels (A-suffix) - preserves amplitude consistency across selected analog inputs |
| Off-Leakage Current | 0.1nA at +25°C - prevents DC offset drift in high-impedance sensor interfaces (e.g., thermocouples, pH electrodes) |
| Off-Isolation | <–90dB at 100kHz (50Ω) - suppresses coupling between inactive and active channels in multi-signal environments |
| Logic Thresholds | 0.8V to 2.4V - ensures reliable switching with standard 5V TTL/CMOS outputs without external biasing |
| Charge Injection | ≤10pC - limits voltage glitch on sampled-hold capacitors in ADC front-ends |
Pinout & Package
MAX4051CSE-T is supplied in a 16-pin QSOP (Quarter-Size Outline Package) with 0.65mm lead pitch, optimized for automated assembly and thermal performance in compact industrial modules.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 4, 5, 12, 13, 14, 15 | NO0–NO7 | Eight bidirectional analog inputs - each connects to COM when selected; no polarity constraint |
| 3 | COM | Common analog terminal - serves as input or output depending on signal flow direction |
| 9, 10, 11 | ADDA, ADDB, ADDC | Binary address inputs - decode 3-bit value to select one of eight NOx paths to COM |
| 6 | INH | Active-low inhibit - forces all switches open regardless of address state; used for system-wide disable |
| 7 | V− | Negative analog supply - tied to GND for single-supply operation; sets lower rail for analog signal swing |
| 8 | GND | Digital ground reference - separate from analog signal path; no current return path for analog signals |
| 16 | V+ | Positive analog/digital supply - powers internal logic translators and switch gates; defines upper analog rail |
Key Features
| Feature | Design Value |
|---|---|
| PIN-compatible with 74HC4051 | Direct drop-in replacement for legacy designs - eliminates PCB redesign and firmware changes |
| Rail-to-rail analog signal handling | Supports full V− to V+ signal range - enables use with unipolar and bipolar sensor outputs without clamping |
| Guaranteed on-resistance flatness | ≤10Ω variation over ±3V input range - minimizes harmonic distortion (<0.04% at 600Ω load) |
| Low crosstalk and off-isolation | <–90dB in 50Ω systems - essential for simultaneous multi-channel acquisition without interference |
| Single-supply operation down to +2.7V | Enables direct interface with Li-ion battery-powered devices - extends operational life without boost converters |

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; 100Ω RON at ±15V, but only specified down to +3V single supply; 1nA off-leakage at +25°C (10× higher than MAX4051CSE-T) | Less suitable for ultra-low-leakage sensor front-ends; better for higher-voltage industrial systems | Select when operating above +12V or requiring wider temp range (–40°C to +125°C) |
| 74HC4051D | Pin-compatible logic-level mux; 120Ω RON at +4.5V; no A-suffix characterization for RON match or leakage; 100nA off-leakage at +25°C | Not suitable for precision DC-coupled applications; acceptable for digital/audio switching where leakage is non-critical | Select for cost-sensitive consumer audio or logic-level signal routing where leakage & matching are secondary |
Compared with ADG408BRUZ and 74HC4051D, the MAX4051CSE-T provides superior leakage performance (0.1nA vs. 1nA/100nA) and tighter on-resistance matching (6Ω vs. unspecified/20Ω), making it optimal for battery-powered precision data acquisition where signal integrity and power efficiency are primary constraints.

FAQ
What is the maximum analog signal voltage range supported by the MAX4051CSE-T?
The MAX4051CSE-T supports rail-to-rail analog signals from V− to V+. With ±5V supplies, this is –5V to +5V; with a +5V single supply (V− = GND), it is 0V to +5V. Absolute maximum analog voltage is limited by V+ and V− ratings: (V− – 2V) to (V+ + 2V), per internal ESD diode clamping.
Does the MAX4051CSE-T require external pull-up or pull-down resistors on its address pins?
No, the MAX4051CSE-T does not require external pull-up or pull-down resistors on ADDA, ADDB, or ADDC. Its digital inputs have guaranteed TTL/CMOS-compatible thresholds (0.8V to 2.4V at +5V supply), and internal input current is ≤1µA - compatible with direct microcontroller GPIO connection without biasing.
Can the MAX4051CSE-T be used with a +3.3V single supply?
Yes, the MAX4051CSE-T operates with a +3.3V single supply (V+ = +3.3V, V− = GND). At this voltage, typical on-resistance is ~250Ω (max 700Ω), and off-leakage remains ≤0.1nA at +25°C. Logic thresholds scale accordingly, remaining compatible with 3.3V CMOS outputs.
What is the purpose of the INH pin on the MAX4051CSE-T?
INH is an active-low inhibit input that forces all eight analog switches into the open (off) state regardless of address pin states. When pulled high (≥2.4V), all channels disconnect; when grounded or held low (≤0.8V), normal address-controlled switching resumes. This enables global channel disable for safety or power-saving modes.
How does the MAX4051CSE-T handle bidirectional signal flow?
The MAX4051CSE-T treats NOx and COM pins identically - either can serve as input or output. Signal direction is unrestricted because its CMOS transmission gates conduct equally well in both directions. This allows flexible routing in applications like shared bus architectures or reversible sensor interfaces without signal-path redesign.
