Product details
Overview
The MAX4524EUB+ from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer configured as a COM-to-NO0/NO1/NO2/NO3 switch with digital address control (ADDA/ADDB) and global inhibit (INH). It delivers 200Ω on-resistance at +5V, 2nA max off-leakage at +25°C, rail-to-rail signal handling, and operates from +2V to +12V - ideal for battery-powered audio routing and low-voltage data-acquisition front-ends.
For engineers reviewing the MAX4524EUB+ datasheet, MAX4524EUB+ pinout, MAX4524EUB+ application, or MAX4524EUB+ equivalent, key selection criteria include guaranteed on-resistance matching (≤8Ω at +5V), TTL/CMOS logic compatibility with single +5V supply, -40°C to +85°C industrial temperature rating, µMAX-10 package footprint, and break-before-make timing (400ns max).
Technical Context
The MAX4524EUB+ implements a CMOS transmission-gate architecture with dual address inputs (ADDA, ADDB) selecting one of four normally-open analog paths between COM and NO0–NO3. Its inhibit input (INH) forces all channels open simultaneously, independent of address state.
All analog terminals (COM, NO0–NO3) support bidirectional rail-to-rail signals up to V+, with ESD protection diodes clamping voltages beyond GND or V+. Logic thresholds (0.8V low / 2.4V high at +5V) ensure direct interface with standard TTL/CMOS outputs without level-shifting.
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 auxiliary rails |
| On-Resistance (RON) | 200Ω max at +5V - ensures minimal signal attenuation and gain error in precision sensor or audio paths |
| On-Resistance Match | ≤8Ω max at +5V - guarantees consistent channel-to-channel gain and phase response in multi-path routing |
| Off-Leakage Current | 2nA max at +25°C - preserves accuracy in high-impedance measurement circuits (e.g., thermocouple, pH probe front-ends) |
| Logic Thresholds | 0.8V low / 2.4V high at +5V - ensures reliable switching with standard 5V microcontroller GPIO without external biasing |
| Operating Temp | -40°C to +85°C - qualified for industrial and automotive under-hood environments requiring extended thermal stability |
| Turn-On/Off Time | 200ns / 180ns at +5V - supports fast multiplexing in real-time data acquisition up to ~2MHz channel rate |
Pinout & Package
Package: 10-pin µMAX (3mm × 3mm, 0.6mm height), exposed pad (EP) connected to V+ per datasheet recommendation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO0) | Analog Normally-Open Input 0 | Signal path connects to COM when ADDA=0, ADDB=0; bidirectional, rail-to-rail capable |
| 2 (NO1) | Analog Normally-Open Input 1 | Connects to COM when ADDA=1, ADDB=0; matched RON ensures uniform channel performance |
| 3 (NO2) | Analog Normally-Open Input 2 | Connects to COM when ADDA=0, ADDB=1; same leakage and capacitance specs as NO0–NO3 |
| 4 (NO3) | Analog Normally-Open Input 3 | Connects to COM when ADDA=1, ADDB=1; 12pF off-capacitance minimizes crosstalk in high-frequency routing |
| 5 (INH) | Inhibit Control Input | Active-high logic: drives all switches open regardless of ADDA/ADDB state - critical for safe power-up sequencing |
| 6 (ADDA) | Address Bit A | LSB of 2-bit binary select; 0.8V/2.4V thresholds allow direct MCU GPIO drive at +5V |
| 7 (ADDB) | Address Bit B | MSB of 2-bit binary select; synchronous with ADDA - no internal clock required |
| 8 (GND) | Digital and Analog Ground Reference | Common return for logic and switch substrate; no analog signal reference to GND - true floating operation |
| 9 (COM) | Analog Common Terminal | Bidirectional hub: routes selected NOx signal in or out; handles ±0.3V beyond rails via ESD diodes |
| 10 (V+) | Positive Supply | Powers internal CMOS gates and sets analog voltage limits; EP pad must be soldered to V+ plane for thermal/safety compliance |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output voltages from GND to V+ - eliminates level-shifting in mixed-supply systems |
| Guaranteed on-resistance match | ≤8Ω max variation across all four channels at +5V - enables precision ratio-metric measurements |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V - allows direct connection to FPGA or MCU I/O without pull-ups or translators |
| Low off-leakage current | 2nA max at +25°C - maintains integrity of high-Z sensor nodes and sample-and-hold circuits |
| Break-before-make switching | 400ns min interval prevents momentary shorting during channel transitions - protects sensitive sources and loads |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524ETB+ | Same electrical specs but in 10-pin TDFN-EP (3mm × 3mm) with exposed pad tied to V+; higher power dissipation rating (1951mW vs. 330mW) | Better thermal performance in high-density PCB layouts; requires different land pattern and reflow profile | Select MAX4524ETB+ for designs needing enhanced thermal management or higher continuous current capability |
| TMUX1104DCUR | 4-channel mux with 1.5Ω typical RON at +5V, 1.2pF off-capacitance, but only rated for -40°C to +125°C and lacks inhibit function | Superior bandwidth and lower distortion for high-fidelity audio, but no global INH - requires software-controlled disable | Select TMUX1104DCUR where ultra-low RON and capacitance are critical, and inhibit functionality is implemented externally |
Compared with MAX4524ETB+, the MAX4524EUB+ offers identical switching performance in a smaller µMAX footprint but lower thermal headroom; compared with TMUX1104DCUR, it trades lower RON and capacitance for integrated inhibit control and proven industrial temperature stability.

FAQ
What is the maximum supply voltage rating for the MAX4524EUB+?
The MAX4524EUB+ has an absolute maximum supply voltage (V+) of +13V, but its specified operational range is +2V to +12V. Operation at +12V is fully characterized for on-resistance, leakage, and switching times. Exceeding +13V risks permanent damage due to internal ESD diode breakdown, as confirmed in the Absolute Maximum Ratings table.
Does the MAX4524EUB+ support bidirectional signal flow?
Yes, the MAX4524EUB+ supports fully bidirectional analog signal flow on all channels (COM ↔ NO0–NO3). The CMOS transmission-gate structure imposes no inherent directionality, and the datasheet explicitly states "signals pass equally well in both directions" - making it suitable for both sensor input multiplexing and DAC output distribution in the MAX4524EUB+ design.
How does the INH pin function in the MAX4524EUB+?
The INH pin on the MAX4524EUB+ is an active-high inhibit control: when driven to logic high (≥2.4V at +5V supply), it forces all four analog switches into the open (non-conducting) state regardless of ADDA/ADDB address inputs. This provides hardware-level channel isolation for safety-critical power sequencing or fault conditions in the MAX4524EUB+ application.
What is the on-resistance flatness specification for the MAX4524EUB+?
The MAX4524EUB+ guarantees 12Ω maximum on-resistance flatness (RFLAT) over the full analog signal range (0V to V+) at +5V supply. Flatness is defined as the difference between maximum and minimum RON measured across the signal swing - critical for minimizing harmonic distortion in audio paths and gain nonlinearity in precision measurement using the MAX4524EUB+.
Is the exposed pad on the MAX4524EUB+ package electrically connected?
Yes, the exposed pad (EP) on the MAX4524EUB+ µMAX package is internally connected to V+ and must be soldered to the V+ copper pour on the PCB. This connection is mandatory for thermal performance, ESD robustness (>2000V HBM), and safe operation - as stated in the Package Information section and confirmed by the topography diagram showing substrate tied to V+ in the MAX4524EUB+ silicon layout.
