Product details
Overview
MAX4582CSE from Maxim Integrated is a dual 4-channel CMOS analog multiplexer configured for bidirectional signal routing in low-voltage systems. It supports ±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 achieves -96dB crosstalk (50Ω) - enabling precision audio/video switching and battery-powered data acquisition.
For engineers reviewing the MAX4582CSE datasheet, MAX4582CSE pinout, MAX4582CSE application, or MAX4582CSE equivalent, this page provides verified electrical specs, package mapping to 16-pin narrow SO, functional pin roles, automotive-grade alternatives, and design-critical leakage/on-resistance behavior across temperature and supply conditions.
Technical Context
The MAX4582CSE implements two independent 4:1 analog multiplexers with shared digital address inputs (A, B) and individual enable control. Each mux channel features rail-to-rail analog signal handling, break-before-make switching (4–20ns), and TTL/CMOS-compatible logic thresholds (0.8V/2.4V at +5V).
Its BICMOS process ensures low charge injection (0.5–5pC), flat on-resistance over signal range (±3V), and high off-isolation (-74dB at 50Ω). Operation is validated from 0°C to +70°C, with ESD protection >2000V per Method 3015.7.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±2V to ±6V dual or +2V to +12V single - enables direct interface with Li-ion, 3.3V, and 5V systems without level shifters |
| On-Resistance | 80Ω max at ±5V - ensures minimal signal attenuation and gain error in precision sensor/ADC front-ends |
| Off-Leakage Current | 1nA max at +25°C - preserves accuracy in high-impedance measurement paths (e.g., pH sensors, thermocouples) |
| Crosstalk | <-96dB at 1MHz (50Ω) - prevents audible artifacts in stereo audio routing and cross-channel interference in multi-sensor DAQ |
| Switching Time | tON/tOFF ≤ 200ns - supports multiplexed sampling up to ~2.5 MSPS in time-critical data acquisition |
| Analog Bandwidth | 50MHz flat response - suitable for composite video (NTSC/PAL) and baseband RF signal routing |
| Logic Compatibility | 0.8V/2.4V thresholds at +5V - interoperates directly with 3.3V and 5V microcontrollers without external translators |
Pinout & Package
MAX4582CSE is housed in a 16-pin narrow SO package (SOIC-16, 3.9mm width), RoHS-compliant, with exposed pad not present (TQFN variant has EP; CSE does not).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | X0–X3 analog inputs | First 4-channel input bank; bidirectional - may serve as inputs or outputs depending on signal flow direction |
| 5, 6, 7, 8 | Y0–Y3 analog inputs | Second independent 4-channel input bank; electrically isolated from X-bank except via common VCC/VEE/GND |
| 9, 10 | A, B address inputs | Binary select lines controlling both mux banks simultaneously - simplifies control logic vs. separate addressing |
| 11 | ENABLE | Active-high global enable - disables all switches when low, reducing system power and preventing signal contention |
| 12, 13 | X, Y outputs | Dedicated output terminals per mux bank; support rail-to-rail swing from VEE to VCC |
| 14 | GND | Digital ground reference only - analog signals are floating between VCC and VEE, with no GND reference |
| 15 | VEE | Negative supply pin - tied to GND for single-supply operation; sets lower analog voltage limit |
| 16 | VCC | Positive supply pin - powers internal logic and analog switch drivers; defines upper analog voltage limit |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full VEE-to-VCC swing without clipping - essential for unipolar/bipolar sensor interfaces and audio line-level signals |
| Guaranteed on-resistance match | ΔRON ≤ 10Ω between channels - minimizes gain mismatch in multi-channel instrumentation amplifier front-ends |
| Low distortion | <0.02% THD at 600Ω - preserves fidelity in audio path switching and high-fidelity signal conditioning |
| High off-isolation | <-74dB at 50Ω - prevents signal bleed between inactive channels in communication circuit routing |
| AEC-Q100 qualified variants available | MAX4582ASE+/AUE/V+T versions rated for -40°C to +125°C - enables drop-in use in automotive infotainment and ADAS sensor hubs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4582ESE+ | Same functionality and pinout; extended temp range (-40°C to +85°C) and higher guaranteed leakage (5nA at +85°C) | Suitable for industrial control cabinets and outdoor telemetry where ambient exceeds +70°C | Select MAX4582ESE+ when operating above 70°C is required; no PCB change needed |
| ADG408BRUZ | 8-channel single mux (not dual 4:1); 100Ω RON at ±5V; 20nA off-leakage at +25°C; different pinout (16-TSSOP, non-pin-compatible) | Better suited for single-bus, high-channel-count routing (e.g., sensor matrix scanning) rather than parallel dual-path routing | Choose ADG408BRUZ only if consolidating to one 8:1 path is acceptable and layout revision is feasible |
Compared with MAX4582ESE+, the MAX4582CSE offers tighter leakage spec at room temperature but narrower thermal rating; versus ADG408BRUZ, it provides true dual-path independence and superior leakage performance, though at the cost of reduced channel count per device.

FAQ
What supply voltages does the MAX4582CSE support?
The MAX4582CSE operates from ±2V to ±6V dual supplies or a single +2V to +12V supply with VEE tied to GND. At ±5V, it delivers 80Ω typical on-resistance and guarantees <1nA off-leakage at +25°C. The device remains functional down to +1.7V single supply, though RON and switching times degrade significantly below +2V.
Is the MAX4582CSE pin-compatible with industry-standard analog multiplexers?
Yes, the MAX4582CSE is pin-compatible with the 74HC4052 and MAX4052 in 16-pin narrow SO packages. Its pinout matches the RCA CD4052 standard: pins 1–4 and 5–8 are X0–X3 and Y0–Y3 inputs, pins 12 and 13 are X and Y outputs, and pins 9–11 are A, B, and ENABLE - enabling drop-in replacement in existing designs.
What is the maximum analog signal bandwidth supported by the MAX4582CSE?
The MAX4582CSE maintains flat frequency response up to 50MHz in 50Ω systems. Above 20MHz, minor on-response peaks appear due to layout-dependent parasitics, while off-isolation degrades at ~20dB/decade. For composite video (up to 6MHz) or audio (20Hz–20kHz), its <0.02% THD and -96dB crosstalk ensure signal integrity without external filtering.
How does the MAX4582CSE handle leakage current in high-impedance sensor applications?
The MAX4582CSE guarantees ≤1nA off-leakage current at +25°C and ≤5nA at +85°C - critical for preserving accuracy in high-Z sensor interfaces like thermistors, pH electrodes, or piezoelectric transducers. Its leakage originates from balanced ESD diodes between each signal pin and VCC/VEE, minimizing net current injection into sensitive nodes.
Does the MAX4582CSE require external protection diodes for overvoltage conditions?
No, the MAX4582CSE integrates reverse ESD-protection diodes between each analog pin and VCC/VEE. However, if analog signals may exceed VCC or fall below VEE, external series diodes (e.g., 1N4148) on VCC/VEE are recommended per Figure 1 in the datasheet to prevent forward conduction - adding ~0.7V headroom reduction but preserving RON and leakage specs.
