Product details
Overview
MAX4581ESE+T from Maxim Integrated is an 8-channel CMOS analog multiplexer configured for rail-to-rail signal switching in low-voltage systems. It operates with ±2V to ±6V dual supplies or +2V to +12V single supply, delivers 80Ω on-resistance at ±5V, guarantees <1nA off-leakage at +25°C, and supports TTL/CMOS logic compatibility - enabling precise signal routing in battery-powered data-acquisition front-ends.
For engineers reviewing the MAX4581ESE+T datasheet, MAX4581ESE+T pinout, MAX4581ESE+T application, or MAX4581ESE+T equivalent, key selection criteria include guaranteed on-resistance matching (±10Ω), break-before-make timing (4–20ns), low crosstalk (<−96dB @50Ω), high off-isolation (<−74dB), and AEC-Q100-compliant variants for automotive signal conditioning.
Technical Context
The MAX4581ESE+T implements a single 8:1 analog multiplexer architecture with three digital address inputs (A, B, C) and an active-low ENABLE terminal. Its internal CMOS switch array uses bipolar-supply-compatible gate drive circuitry that translates TTL/CMOS logic levels into full-rail analog control signals referenced to VCC and VEE.
All eight analog channels (X0–X7) share identical electrical characteristics: guaranteed on-resistance flatness (±12Ω), charge injection ≤5pC, and output capacitance of 25pF (on) / 18pF (off) at +25°C. The device exhibits no ground reference for analog paths - signal integrity depends solely on VCC–VEE voltage compliance and ESD diode leakage balance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel single-pole, 8-throw (8:1) analog multiplexer |
| Supply Range | ±2V to ±6V dual supply or +2V to +12V single supply - enables operation in 3.3V, 5V, and 12V systems without level-shifting |
| On-Resistance | 80Ω max at ±5V - ensures minimal signal attenuation and gain error in precision sensor interfaces |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement nodes (e.g., thermocouple, pH electrode) |
| Crosstalk | <−96dB at 1MHz, 50Ω load - prevents channel-to-channel interference in multi-sensor audio/video routing |
| Off-Isolation | <−74dB at 1MHz, 50Ω load - maintains signal separation between active and inactive channels |
| Break-Before-Make | 4–20ns - eliminates momentary short-circuits during channel switching in power-sensitive circuits |
Pinout & Package
MAX4581ESE+T is housed in a 16-pin narrow SO (Small Outline) package with exposed pad (RoHS-compliant, lead-free). Pin functions are fully defined per Maxim's pin-compatible mapping to industry-standard CD4051/MAX4051.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–8, 10–12, 14–15 | X0–X7 analog I/O | Bidirectional analog terminals - interchangeable as input or output; support rail-to-rail signal swing |
| 9 | ENABLE (active-low) | Global enable/disable control - pulls all switches open when high; requires pull-down for default-on operation |
| 13 | X (common output) | Single-pole common node - connects to selected X0–X7 channel; no internal ground reference |
| 16 | VCC | Positive supply for analog switches and logic interface - sets upper analog signal limit |
| 7 | GND | Digital ground reference only - analog signals float between VCC and VEE |
| 6 | VEE | Negative analog supply - sets lower analog signal limit; connect to GND for single-supply use |
| 10–12 | A, B, C address inputs | Binary-select lines - decode 3-bit address to route X0–X7 to X; TTL/CMOS compatible at +5V |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full VEE-to-VCC voltage range without clipping - essential for ±5V op-amp interfacing and unipolar/bipolar sensor outputs |
| Guaranteed on-resistance match | ΔRON ≤10Ω across all 8 channels - minimizes gain mismatch in multi-channel instrumentation amplifiers |
| Low distortion & crosstalk | THD <0.02% (600Ω), crosstalk <−96dB - preserves fidelity in audio routing and high-resolution ADC front-ends |
| TTL/CMOS logic compatibility | 0.8V–2.4V input thresholds at +5V supply - eliminates need for external level shifters in microcontroller-driven systems |
| Extended temperature operation | Rated for −40°C to +85°C - qualified for industrial automation and automotive under-hood signal conditioning |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4051ACPE+ | Same 8:1 configuration, but rated 0°C to +70°C only; higher typical on-resistance (100Ω @ ±5V) | Not qualified for extended temperature industrial or automotive use | Select when cost sensitivity outweighs temperature range and leakage requirements |
| ADG1408BRUZ | 8:1 mux with lower on-resistance (4.7Ω), but requires ≥±4.5V dual supply or ≥9V single supply | Unsuitable for +3.3V or +5V-only systems without boost circuitry | Select when ultra-low RON is critical and supply headroom permits |
Compared with MAX4051ACPE+, MAX4581ESE+T offers wider temperature range and lower leakage; compared with ADG1408BRUZ, it supports lower supply voltages at the expense of higher on-resistance - making MAX4581ESE+T optimal for battery-constrained, wide-temp, moderate-precision applications.

FAQ
What supply configurations does the MAX4581ESE+T support?
The MAX4581ESE+T supports both dual-supply (±2V to ±6V) and single-supply (+2V to +12V) operation. When using single supply, VEE must be tied to GND. The device maintains rail-to-rail analog signal handling across all supported ranges, and logic inputs remain TTL/CMOS-compatible at +5V. For MAX4581ESE+T, the −40°C to +85°C rating applies to both configurations.
Does the MAX4581ESE+T require external pull-up or pull-down resistors on its address or enable pins?
No, the MAX4581ESE+T does not require external biasing on A, B, C, or ENABLE pins. Its digital inputs have guaranteed 0.8V–2.4V logic thresholds at +5V supply, and internal input current is limited to ±1µA. However, ENABLE is active-low and defaults to disabled if left floating; a 10kΩ pull-down resistor is recommended for fail-safe operation in noise-prone environments.
Can the MAX4581ESE+T handle bipolar analog signals when powered from a single +5V supply?
No - with VEE tied to GND on a single +5V supply, the MAX4581ESE+T supports only 0V to +5V analog signals. Bipolar operation (e.g., ±2.5V) requires dual supplies (e.g., VCC = +2.5V, VEE = −2.5V). Attempting to apply negative voltages with VEE = GND forward-biases internal ESD diodes and risks damage or excessive leakage.
How is analog signal isolation maintained between channels in the MAX4581ESE+T?
Analog isolation in the MAX4581ESE+T relies on high off-isolation (−74dB at 1MHz) and low crosstalk (−96dB at 1MHz, 50Ω). These values stem from optimized switch geometry, guard-ring layout, and low output off-capacitance (18pF). Isolation performance degrades above 10MHz due to capacitive coupling - for RF applications, additional board-level shielding or discrete filtering is required alongside MAX4581ESE+T.
Is the MAX4581ESE+T pin-compatible with legacy CD4051 devices?
Yes - the MAX4581ESE+T is explicitly pin-compatible with the CD4051B and MAX4051, sharing identical pinout, truth table, and functional diagram per RCA's 1972 CD4051 specification. This allows drop-in replacement in existing designs, delivering superior specs: lower on-resistance (80Ω vs. 120Ω), lower leakage (1nA vs. 100nA), and guaranteed performance over −40°C to +85°C.
