Product details
Overview
MAX4524EUB from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer/demultiplexer IC operating from +2V to +12V, featuring 200Ω on-resistance at +5V, 2nA max off-leakage at +25°C, and rail-to-rail analog signal handling - used in battery-powered audio/video routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4524EUB datasheet, MAX4524EUB pinout, MAX4524EUB application, or MAX4524EUB equivalent, key selection criteria include guaranteed on-resistance matching (±8Ω), TTL/CMOS logic compatibility with +5V supply, inhibit-controlled channel shutdown, -40°C to +85°C industrial temperature rating, and µMAX-10 package footprint constraints.
Technical Context
The MAX4524EUB implements four independent bidirectional analog switches controlled by two address bits (ADDA, ADDB) and a global inhibit (INH) input that forces all channels open simultaneously. Its CMOS transmission-gate architecture supports true rail-to-rail analog signals (VCOM, VNOx = GND to V+), with internal level translators enabling TTL/CMOS-compatible digital inputs across its full supply range.
Switching performance is characterized by 200ns typical turn-on/off times (at +5V, 300Ω load, 35pF), 400ns maximum break-before-make interval, and <0.2% THD at 20Hz–20kHz into 600Ω - optimized for precision signal routing where leakage (<2nA off, <1nA on), charge injection (<5pC), and channel-to-channel isolation (>74dB) are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V or 5V systems without level-shifting circuitry. |
| On-Resistance (RON) | 200Ω max at +5V - ensures minimal signal attenuation and voltage drop in low-level analog paths. |
| On-Resistance Match | ±8Ω max between channels at +5V - preserves gain/phase matching in multi-channel instrumentation or audio summing. |
| Off-Leakage Current | 2nA max at +25°C, 20nA max at +85°C - prevents DC error accumulation in high-impedance sensor front-ends or sample-hold circuits. |
| Logic Thresholds | VIL = 0.8V, VIH = 2.4V at +5V - guarantees reliable interface with standard TTL/CMOS outputs without external biasing. |
| Analog Signal Range | Rail-to-rail (GND to V+) - supports full dynamic range of unipolar or bipolar signals referenced to system ground. |
| Turn-On/Off Time | 200ns typical at +5V - suitable for multiplexing sampling rates up to ~1MHz in data-acquisition applications. |
Pinout & Package
MAX4524EUB uses a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), thermally enhanced with exposed pad connected to V+. Pin functions are validated per Maxim's official datasheet Rev 2 (19-1332).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NO0 | Analog switch normally open input 0 | Bidirectional signal path; connects to COM when selected via ADDA/ADDB = 00. |
| 2 NO1 | Analog switch normally open input 1 | Bidirectional signal path; connects to COM when selected via ADDA/ADDB = 01. |
| 3 NO2 | Analog switch normally open input 2 | Bidirectional signal path; connects to COM when selected via ADDA/ADDB = 10. |
| 4 NO3 | Analog switch normally open input 3 | Bidirectional signal path; connects to COM when selected via ADDA/ADDB = 11. |
| 5 INH | Inhibit control input | Active-high logic input; drives all switches open (high-Z) when logic high, overriding address inputs. |
| 6 ADDA | Address bit A | LSB of 2-bit binary channel select; determines NO0–NO3 connection to COM in conjunction with ADDB. |
| 7 ADDB | Address bit B | MSB of 2-bit binary channel select; used with ADDA to decode one of four analog paths. |
| 8 GND | Digital/analog reference ground | Return path for internal logic and ESD protection diodes; no analog signal reference - all analog pins swing rail-to-rail vs. GND. |
| 9 COM | Common analog terminal | Shared bidirectional I/O node; routes selected NOx signal to/from external circuitry. |
| 10 V+ | Positive supply | Powers internal CMOS switches and level translators; sets upper analog voltage limit and biases ESD diodes. |
Key Features
| Feature | Design Value |
|---|---|
| Single-supply operation | Eliminates need for dual ±5V rails in portable or space-constrained designs - simplifies power architecture. |
| Guaranteed RON match | ±8Ω max mismatch at +5V ensures consistent gain scaling across channels in multi-input sensor interfaces. |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V allow direct connection to microcontroller GPIOs without pull-ups or level shifters. |
| Low off-leakage current | 2nA max at +25°C minimizes error voltage in high-impedance measurement nodes (e.g., pH sensors, photodiode amps). |
| Small µMAX package | 3mm × 3mm footprint saves PCB area in handheld medical devices, test equipment, and modular instrumentation. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524ETB | TDFN-EP (3mm × 3mm) vs. µMAX; identical electrical specs; exposed pad improves thermal dissipation. | Better suited for high-density layouts requiring lower thermal resistance or automated optical inspection compatibility. | Select MAX4524ETB when board-level thermal management or reflow process stability is prioritized over legacy µMAX footprint reuse. |
| ADG1404BRUZ | 4-channel mux with 1.5Ω RON (at ±15V), higher supply range (±5V to ±16.5V), but requires dual supply and larger 16-TSSOP package. | Targeted at high-precision industrial DAQ where ultra-low RON and low tempco outweigh single-supply convenience. | Choose ADG1404BRUZ only if sub-2Ω on-resistance and dual-supply operation are mandatory - not a drop-in replacement for MAX4524EUB. |
Compared with MAX4524ETB, the MAX4524EUB offers identical functionality in a legacy µMAX package ideal for space-constrained designs with existing layout constraints; versus ADG1404BRUZ, it trades lower RON for single-supply simplicity, smaller size, and lower cost in battery-operated systems.

FAQ
What is the operating temperature range of the MAX4524EUB?
The MAX4524EUB is rated for operation from -40°C to +85°C, making it suitable for industrial and automotive-adjacent environments where ambient temperatures exceed commercial-grade limits. This extended range is confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet (Rev 2, p.2).
Does the MAX4524EUB support rail-to-rail analog signals?
Yes, the MAX4524EUB supports rail-to-rail analog signals - meaning its COM and NOx terminals can pass voltages from GND to V+ without clipping. This is explicitly stated in the General Description and verified in the Electrical Characteristics table under "Analog Signal Range" (VCOM, VNO = V− to V+).
What is the maximum on-resistance of the MAX4524EUB at +5V supply?
The maximum on-resistance of the MAX4524EUB at +5V supply is 200Ω, as specified in the Electrical Characteristics table (V+ = 4.5V to 5.5V, TA = TMIN to TMAX). This value is guaranteed across the full operating temperature range and is critical for minimizing signal loss in precision analog paths.
How does the INH (inhibit) pin function on the MAX4524EUB?
The INH pin on the MAX4524EUB is an active-high control input that forces all four analog switches into the open (high-impedance) state regardless of ADDA/ADDB settings. When INH = logic high, no NOx-to-COM path is closed - enabling safe signal isolation during system reset or fault conditions.
Is the MAX4524EUB pin-compatible with other variants in the MAX4524 family?
Yes, the MAX4524EUB shares identical pinout and functionality with MAX4524CUB and MAX4524ETB - all are 10-pin devices with the same µMAX or TDFN footprint and identical signal assignments. Differences are limited to temperature grade (E vs. C) and package type (µMAX vs. TDFN), not pin configuration.
