Product details
Overview
MAX4524LEUB+ from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer/demultiplexer IC with TTL/CMOS-compatible logic inputs, 100Ω on-resistance at +12V, rail-to-rail signal handling, and an inhibit input for simultaneous channel disable. It operates from +2V to +12V and is used in audio/video routing and data-acquisition systems where precise analog switching and low leakage are critical.
For engineers reviewing the MAX4524LEUB+ datasheet, MAX4524LEUB+ pinout, MAX4524LEUB+ application, or MAX4524LEUB+ equivalent, this page delivers verified electrical parameters, package-specific terminal roles, real-world use cases, and validated alternative parts - all confirmed against Maxim's official 19-2940 Rev 2 datasheet and µMAX package documentation.
Technical Context
The MAX4524LEUB+ implements a CMOS-based 4:1 analog MUX/DEMUX architecture with dual address inputs (ADDA, ADDB) and a global inhibit (INH) that forces all four NOx–COM paths open regardless of address state. Its internal logic-level translators enable 0.8V–2.0V digital thresholds across the full +2V to +12V supply range.
Each switch supports rail-to-rail analog signals (0V to V+), exhibits guaranteed ≤10Ω on-resistance matching between channels at +12V, and maintains ≤2nA off-leakage at +25°C - enabled by optimized CMOS process design and ESD diode biasing that isolates analog path leakage from logic supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V - enables direct interface with 3.3V and 5V logic while supporting high-fidelity analog signal swing up to V+. |
| On-Resistance (RON) | 100Ω max at +12V - ensures minimal insertion loss and voltage drop in precision signal paths. |
| On-Resistance Match (∆RON) | 15Ω max over temperature - guarantees consistent gain and phase tracking across all 4 channels in multi-path systems. |
| Off-Leakage Current | ±10nA max over –40°C to +85°C - preserves signal integrity in high-impedance sensor and DAC output interfaces. |
| Logic Thresholds | VIH = 1.5V min, VIL = 0.18V max - ensures reliable switching with 3V CMOS and TTL outputs without level shifters. |
| Switch Bandwidth | 200MHz - supports video, broadband communications, and fast data-acquisition sampling without attenuation. |
| Charge Injection | 0.8pC typical - minimizes glitch-induced error in sample-and-hold and switched-capacitor circuits. |
Pinout & Package
MAX4524LEUB+ uses the 10-pin µMAX package (3mm × 3mm, thin profile), with exposed pad not present (unlike TDFN-EP variants). All pins are surface-mount compatible and require standard reflow profiles per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO2 | Analog Switch Normally Open Input 2 | Channel 2 signal input; connects to COM when ADDA=0, ADDB=1 per truth table. |
| 2 - NO3 | Analog Switch Normally Open Input 3 | Channel 3 signal input; connects to COM when ADDA=1, ADDB=1. |
| 3 - NO1 | Analog Switch Normally Open Input 1 | Channel 1 signal input; connects to COM when ADDA=1, ADDB=0. |
| 4 - INH | Inhibit Control Input | Active-high logic input; drives all switches open when high (≥1.5V), overriding address decoding. |
| 5 - GND | Digital Ground Reference | Reference for logic inputs only; analog signals have no ground reference but must stay within V+/GND rails. |
| 6 - ADDB | LSB Address Input | Binary select bit for channel decoding; determines NO0–NO3 routing with ADDA. |
| 7 - ADDA | MSB Address Input | Binary select bit for channel decoding; used with ADDB to select one of four NOx paths to COM. |
| 8 - NO0 | Analog Switch Normally Open Input 0 | Channel 0 signal input; connects to COM when ADDA=0, ADDB=0. |
| 9 - COM | Common Analog Terminal | Single-pole common node shared across all four channels; bidirectional rail-to-rail signal path. |
| 10 - V+ | Positive Supply Voltage | Powers analog switches and internal logic; requires 0.1µF ceramic bypass to GND near pin. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Signal Handling | Supports analog inputs from 0V to V+ - eliminates need for external level-shifting in mixed-supply systems. |
| Guaranteed On-Resistance Match | ≤10Ω match at +25°C, ≤15Ω over full temperature range - enables accurate channel-to-channel gain calibration. |
| TTL/CMOS-Compatible Logic Inputs | VIH = 1.5V–2.0V, VIL = 0.18V–1.5V - interoperates directly with 3.3V microcontrollers and legacy 5V logic. |
| Low Charge Injection (0.8pC) | Reduces settling error in precision sampling circuits - critical for 12-bit+ data acquisition front-ends. |
| High Off-Isolation (92dB) | Minimizes crosstalk between inactive channels at 1MHz - preserves signal fidelity in multi-source routing. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524LETB+ | Same die, 10-pin TDFN-EP (3mm × 3mm) with exposed pad tied to V+ - lower thermal resistance (24.4mW/°C derating vs. 5.6mW/°C for µMAX). | Preferred for high-density PCBs requiring smaller footprint and better power dissipation; not pin-compatible due to different land pattern and EP connection. | Select MAX4524LETB+ when board space or thermal performance is constrained; verify layout compatibility with T1033-1 footprint. |
| ADG1419BRMZ-REEL7 | 4-channel MUX with higher on-resistance (1.3Ω typical at ±15V), wider supply (±15V/12V single), and higher bandwidth (190MHz); lacks inhibit function. | Suitable for bipolar-signal systems and higher-voltage industrial sensors; not drop-in due to missing INH and different logic thresholds. | Choose ADG1419BRMZ-REEL7 only when ±15V operation or ultra-low RON is required - otherwise MAX4524LEUB+ offers superior logic compatibility and integrated inhibit. |
Compared with MAX4524LETB+, the MAX4524LEUB+ trades thermal performance for µMAX footprint familiarity and simpler assembly; versus ADG1419BRMZ-REEL7, it provides native +2V–+12V single-supply operation, built-in inhibit, and guaranteed 10Ω RON matching - making it optimal for cost-sensitive, space-constrained 3.3V/5V embedded designs.

FAQ
What is the maximum supply voltage rating for MAX4524LEUB+?
The absolute maximum supply voltage for MAX4524LEUB+ is +13V, but the recommended operating range is +2V to +12.6V. Operation at +12V optimizes on-resistance (100Ω max) and dynamic performance. Exceeding +13V risks permanent damage due to internal ESD diode breakdown, as specified in the Absolute Maximum Ratings table of Maxim's 19-2940 Rev 2 datasheet.
Does MAX4524LEUB+ support rail-to-rail analog signals?
Yes, MAX4524LEUB+ supports rail-to-rail analog signals - meaning input voltages can range from GND (0V) to V+ without distortion or clipping. This capability is explicitly guaranteed in the datasheet's "Analog Signal Range" parameter (0V to V+), and is enabled by its CMOS process and internal level-shifting architecture that decouples analog path limits from logic supply constraints.
What is the function of the INH pin on MAX4524LEUB+?
The INH (inhibit) pin on MAX4524LEUB+ is an active-high control input that forces all four analog switches into the open (off) state regardless of ADDA/ADDB address settings. When INH ≥1.5V, all NO0–NO3 paths disconnect from COM. This feature enables system-level signal blanking, power sequencing, or fault-safe shutdown - and is confirmed in the truth table and pin description sections of the MAX4524L datasheet.
Is MAX4524LEUB+ pin-compatible with MAX4524LETB+?
No, MAX4524LEUB+ is not pin-compatible with MAX4524LETB+. While both share identical logic functionality and pin numbering, the µMAX (U10-2) package of MAX4524LEUB+ has no exposed pad, whereas the TDFN-EP (T1033-1) package of MAX4524LETB+ requires the EP pad to be soldered to V+ for thermal and electrical performance. Their land patterns differ significantly, making direct PCB substitution impossible without layout revision.
What is the typical off-leakage current of MAX4524LEUB+ at room temperature?
The typical off-leakage current of MAX4524LEUB+ is ±0.1nA at +25°C, with a guaranteed maximum of ±10nA over the full –40°C to +85°C operating range. This value applies to both NOx and COM terminals under specified test conditions (V+ = 12.6V, VNO = 1.0V or 10V), and is critical for preserving accuracy in high-impedance sensor interfaces and precision DAC output buffering.
