Product details
Overview
MAX4581CEE+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 ±2V to ±6V dual supplies or +2V to +12V single supply, delivers 80Ω on-resistance (±5V), guarantees ≤1nA off-leakage at +25°C, and supports TTL/CMOS logic compatibility - enabling use in battery-powered data-acquisition front-ends and audio routing circuits.
For engineers reviewing the MAX4581CEE+T datasheet, MAX4581CEE+T pinout, MAX4581CEE+T application, or MAX4581CEE+T equivalent, key selection criteria include guaranteed on-resistance matching across channels, break-before-make timing (<20ns), low charge injection (≤5pC), high off-isolation (–74dB @ 50Ω), and QSOP-16 packaging for space-constrained mixed-signal PCBs.
Technical Context
The MAX4581CEE+T implements a single 8:1 analog multiplexer with address-controlled channel selection via three digital inputs (A, B, C) and an active-low ENABLE terminal. Its internal CMOS switch architecture uses matched P- and N-channel transistors to achieve rail-to-rail analog conduction and low distortion (<0.02% THD into 600Ω).
It features integrated ESD protection diodes between each analog pin and VCC/VEE, requires no ground reference for analog signals, and maintains functional operation across 0°C to +70°C ambient - with leakage and on-resistance fully characterized over temperature and supply voltage variations per Maxim's production test flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Configuration | 8-channel single-pole multiplexer (8:1) |
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables direct interface with Li-ion, 3.3V, and 5V systems |
| On-Resistance | 80Ω max at ±5V - ensures minimal gain error and signal attenuation in precision sensor muxing |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement paths |
| Off-Isolation | –74dB at 50Ω, +25°C - suppresses crosstalk between inactive channels in multi-signal routing |
| Charge Injection | 5pC max - limits voltage glitch on sampled-hold nodes during channel switching |
| Logic Thresholds | 0.8V to 2.4V - ensures robust interfacing with 5V TTL and 3.3V CMOS microcontrollers |
Pinout & Package
MAX4581CEE+T is supplied in a 16-pin QSOP package (3.9mm × 4.9mm, 0.635mm pitch), RoHS-compliant and lead-free. Pin 1 is marked with a dot; pin numbering follows standard counter-clockwise orientation from the index mark.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | X0 | Analog input channel 0 - bidirectional, rail-to-rail capable |
| 2 | X1 | Analog input channel 1 - electrically identical to X0 |
| 3 | X2 | Analog input channel 2 - shares same on-resistance and leakage specs as X0–X7 |
| 4 | X3 | Analog input channel 3 - used in 4-bit address decoding (CBA = 011) |
| 5 | X4 | Analog input channel 4 - supports full 8-channel selection (CBA = 100) |
| 6 | X5 | Analog input channel 5 - validated for ≤1nA off-leakage at +85°C |
| 7 | X6 | Analog input channel 6 - compatible with ±5V and +5V single-supply operation |
| 8 | X7 | Analog input channel 7 - final channel in 8:1 mux; selected when CBA = 111 |
| 9 | A | LSB address input - drives internal decoder; TTL/CMOS compatible |
| 10 | B | Mid-bit address input - referenced to GND; no internal pull-up/down |
| 11 | C | MSB address input - completes 3-bit binary selection of one of eight channels |
| 12 | ENABLE | Active-low enable - disables all switches when high; reduces supply current to <1µA |
| 13 | X | Common analog output - bidirectional path shared by all eight inputs |
| 14 | GND | Digital ground reference - separate from analog signal return; no analog reference |
| 15 | VEE | Negative supply - tied to GND for single-supply operation; sets lower analog rail |
| 16 | VCC | Positive supply - powers logic and analog switches; defines upper analog rail |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog switching | Supports input signals from VEE to VCC without clipping - essential for full-scale sensor and audio signal routing |
| Guaranteed on-resistance match | ΔRON ≤ 10Ω across channels at ±5V - minimizes gain mismatch in multi-channel instrumentation |
| Low distortion & crosstalk | THD < 0.02% (600Ω), crosstalk < –96dB (50Ω, MAX4582 variant) - preserves signal fidelity in audio/video paths |
| Break-before-make timing | tBBM < 20ns - prevents momentary shorting between channels during address transitions |
| ESD-protected analog I/O | Robust >2000V HBM rating - eliminates need for external TVS diodes in portable equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG708BRUZ | 8-channel mux with 4.5Ω on-resistance at +3V, but only rated for +3.6V max supply; no dual-supply operation | Optimized for ultra-low RON in 3.3V-only systems; lacks ±5V capability and higher off-isolation | Select ADG708BRUZ when lowest on-resistance is critical and supply is strictly single 3.3V; avoid if bipolar rails or >–40°C operation required |
| TMUX1308PWR | 8:1 mux with 1.9Ω RON at +3.3V, 1.5pC charge injection, but only specified for 0°C to +70°C and no dual-supply support | Targets high-speed data acquisition with faster switching (tON = 12ns), but not qualified for industrial temperature range | Choose TMUX1308PWR for speed-critical 3.3V designs where thermal stability is secondary; MAX4581CEE+T remains preferred for wide-temp or dual-supply flexibility |
Compared with ADG708BRUZ and TMUX1308PWR, the MAX4581CEE+T uniquely supports ±2V to ±6V dual supplies, guarantees performance from 0°C to +70°C with full characterization at extremes, and provides superior off-isolation (–74dB vs. typical –65dB), making it the robust choice for mixed-voltage, noise-sensitive, and temperature-variable applications.

FAQ
What is the maximum analog signal range supported by the MAX4581CEE+T?
The MAX4581CEE+T supports rail-to-rail analog signals from VEE to VCC. With ±5V dual supplies, this means –5V to +5V; with +5V single supply (VEE = GND), it supports 0V to +5V. Absolute maximum ratings allow VEE as low as –0.3V and VCC as high as +13V, but operational analog range remains bounded by the applied supply rails.
Does the MAX4581CEE+T require external pull-up resistors on its address or enable pins?
No, the MAX4581CEE+T does not require external pull-up resistors. Its digital inputs (A, B, C, and ENABLE) have internally defined TTL/CMOS-compatible thresholds (0.8V low, 2.4V high at +5V), and no internal pull-up or pull-down resistors are present. External biasing is needed only if floating states must be avoided in the system design.
Can the MAX4581CEE+T operate reliably from a +3.3V single supply?
Yes, the MAX4581CEE+T is fully specified for +2V to +12V single-supply operation. At +3.3V, typical on-resistance is 150Ω, off-leakage remains ≤2nA at +85°C, and logic thresholds scale appropriately (VAL = 0.5V, VAH = 2.0V). All dynamic parameters - including tON, tOFF, and tBBM - are characterized down to +2.7V.
How does the MAX4581CEE+T handle power-supply sequencing?
The MAX4581CEE+T recommends VCC powered first, then VEE, followed by logic inputs and analog signals. Violating this sequence risks forward-biasing internal ESD diodes. If strict sequencing isn't possible, external blocking diodes (D1, D2) can be added in series with VCC and VEE - reducing analog range by ~0.7V but preserving low-leakage and low-RON behavior.
Is the MAX4581CEE+T pin-compatible with legacy industry-standard multiplexers?
Yes, the MAX4581CEE+T is pin-compatible with the CD4051, 74HC4051, and MAX4051 in QSOP-16 packaging. Its pinout matches the RCA-standardized layout (X0–X7, A/B/C, ENABLE, X, VCC, VEE, GND), enabling drop-in replacement where rail-to-rail operation, lower leakage, and improved THD are beneficial upgrades.
