Product details
Overview
MAX4581CSE+TGA8 from Maxim Integrated is an 8-channel CMOS analog multiplexer configured for rail-to-rail signal switching in low-voltage systems. It operates on ±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 MAX4581CSE+TGA8 datasheet, MAX4581CSE+TGA8 pinout, MAX4581CSE+TGA8 application, or MAX4581CSE+TGA8 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 compatibility with 74HC4051 pinout for drop-in replacement in legacy designs.
Technical Context
The MAX4581CSE+TGA8 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 matched P- and N-channel transistors to achieve rail-to-rail analog conduction and low distortion (<0.02% THD @600Ω).
Switch control logic follows standard binary decoding per Table 1: inputs A/B/C select one of eight X₀–X₇ channels to connect to the common X output, while ENABLE disables all paths when high. The device features integrated ESD protection diodes between each analog pin and VCC/VEE, requiring proper supply sequencing (VCC before VEE) to avoid latch-up.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables operation across industrial, automotive, and portable voltage rails |
| On-Resistance (RON) | 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 paths (e.g., thermocouple, pH electrode) |
| Crosstalk | <−96dB @50Ω, 1MHz - prevents interference between adjacent channels in multi-signal routing |
| Off-Isolation | <−74dB @50Ω - maintains channel separation during inactive states in mixed-signal systems |
| THD | <0.02% @600Ω, 20Hz–20kHz - supports high-fidelity audio and instrumentation-grade signal integrity |
| Break-Before-Make | 4–20ns - eliminates momentary shorting during channel transitions in critical analog sampling |
Pinout & Package
MAX4581CSE+TGA8 is housed in a 16-pin narrow SO (Small Outline) package with 1.27mm pitch, RoHS-compliant, lead-free finish, and exposed pad not present (non-TQFN variant). Pin functions are defined per Maxim's CD4051-compatible nomenclature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| X₀–X₇ | Analog input channels 0–7 | Bi-directional, interchangeable signal terminals; support rail-to-rail analog voltages up to VCC–VEE range |
| X | Common analog output | Single-pole connection point; selected channel routes bidirectionally through this pin |
| A, B, C | Digital address inputs | Binary-coded selection of X₀–X₇; logic thresholds 0.8V/2.4V ensure TTL/CMOS compatibility at +5V supply |
| ENABLE | Active-low enable control | Pulls all switches open when high; allows global channel disable without address reconfiguration |
| VCC | Positive supply | Powers internal logic and PMOS switch drivers; must be applied before VEE to prevent ESD diode conduction |
| VEE | Negative supply | Powers NMOS switch drivers; tied to GND for single-supply operation (+2V to +12V) |
| GND | Digital ground reference | Logic-level reference only; no analog signal path to ground - analog signals float between VCC and VEE |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output voltages from VEE to VCC - eliminates level-shifting in ±5V or +3.3V systems |
| Guaranteed on-resistance match | ≤10Ω difference between any two channels - critical for gain-matched multi-channel ADC front-ends |
| Low charge injection | 0.5–5pC - minimizes voltage glitch on sample-hold capacitors during switching |
| TTL/CMOS logic compatibility | 0.8V to 2.4V input thresholds at +5V supply - interoperable with microcontrollers and FPGAs without level shifters |
| Pin-compatible with 74HC4051 | Identical pinout and truth table - enables direct replacement in existing PCB layouts |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4581CSE+ | Same die, identical specifications, same narrow SO package - differs only in tape-and-reel packaging (TGA8 denotes 2500-piece reel) | No functional or electrical difference; suitable for identical use cases including production builds and prototyping | Select MAX4581CSE+TGA8 for volume automated assembly; MAX4581CSE+ for smaller-batch hand-solder or evaluation |
| ADG408BRUZ | 8:1 CMOS mux with 75Ω RON (±15V supply), higher 25nA off-leakage at +25°C, and different pinout (non-74HC4051 compatible) | Requires PCB redesign due to incompatible pin mapping; better suited for ±15V industrial systems than low-voltage portable designs | Choose ADG408BRUZ only when ±15V operation is required and layout revision is acceptable |
Compared with MAX4581CSE+ and ADG408BRUZ, the MAX4581CSE+TGA8 offers identical electrical performance to MAX4581CSE+ but optimized for high-volume SMT placement, while ADG408BRUZ trades lower on-resistance for higher leakage and non-interchangeable layout - making MAX4581CSE+TGA8 the preferred choice for cost-sensitive, space-constrained, and legacy-pin-compatible designs.

FAQ
What supply configurations does the MAX4581CSE+TGA8 support?
The MAX4581CSE+TGA8 supports dual supplies from ±2V to ±6V and single supplies from +2V to +12V. When using single supply, VEE must be tied to GND. Operation below +2V is not specified; at +1.7V it may function but with degraded on-resistance and timing. The MAX4581CSE+TGA8 requires correct sequencing: VCC powered first, then VEE, then logic/analog signals to prevent ESD diode conduction.
Is the MAX4581CSE+TGA8 pin-compatible with the 74HC4051?
Yes, the MAX4581CSE+TGA8 is fully pin-compatible and functionally identical to the 74HC4051, including matching pin assignments (X₀–X₇, X, A/B/C, ENABLE, VCC, VEE, GND) and truth table behavior. This allows direct drop-in replacement in existing designs without PCB modification - a key advantage confirmed in Maxim's Applications Information section and Pin Description table.
What is the maximum off-isolation and crosstalk performance of the MAX4581CSE+TGA8?
The MAX4581CSE+TGA8 delivers off-isolation of <−74dB and crosstalk of <−96dB, both measured at 50Ω and 1MHz. These values are guaranteed over temperature and supply conditions per the Electrical Characteristics tables. The high off-isolation ensures minimal signal bleed-through to unselected channels, while the low crosstalk prevents interference between active and adjacent paths - essential for multi-channel precision measurement systems using the MAX4581CSE+TGA8.
How does the MAX4581CSE+TGA8 handle analog signal polarity and grounding?
The MAX4581CSE+TGA8 has no internal ground reference for analog signals: they are strictly bounded between VEE and VCC. Signals pass bidirectionally with rail-to-rail capability, and there is no connection between analog paths and GND. GND serves only as the digital logic reference. This architecture enables true floating differential signal routing - a defining feature of the MAX4581CSE+TGA8 that distinguishes it from ground-referenced switches.
What is the significance of the "TGA8" suffix in MAX4581CSE+TGA8?
The "TGA8" suffix indicates a tape-and-reel packaging option containing 2500 units per reel, compliant with EIA-481-D standards. It shares identical die, electrical specifications, and narrow SO package dimensions with the base MAX4581CSE+, differing only in packaging format - making MAX4581CSE+TGA8 the optimal choice for automated SMT assembly lines requiring high-volume, machine-placed components.
