Product details
Overview
The MAX4524EUB+T from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer configured as a 1-of-4 switch with inhibit control, operating from +2V to +12V, delivering 200Ω on-resistance at +5V, 500Ω at +3V, and rail-to-rail signal handling for battery-powered audio routing and data-acquisition systems.
For engineers reviewing the MAX4524EUB+T datasheet, MAX4524EUB+T pinout, MAX4524EUB+T application, or MAX4524EUB+T equivalent, this page provides verified electrical parameters, µMAX package layout, truth-table–driven switching behavior, leakage and crosstalk performance at temperature extremes, and real-world selection guidance against functionally aligned alternatives.
Technical Context
The MAX4524EUB+T implements a CMOS transmission-gate architecture with dual address inputs (ADDA/ADDB) selecting one of four normally open analog paths (NO0–NO3) to a common terminal (COM), while INH asserts global disable by forcing all switches into high-impedance off-state. Its logic thresholds (0.8V/2.4V at +5V) ensure TTL/CMOS compatibility without level-shifting.
Each channel supports bidirectional rail-to-rail analog signals up to V+, with guaranteed 8Ω on-resistance matching between channels at +5V and 2nA max on-leakage at +25°C. Off-isolation exceeds –75dB at 1MHz, and charge injection is limited to 5pC - critical for precision sampling in low-power data converters.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V or 5V battery-powered systems without auxiliary rails |
| On-Resistance (RON) | 200Ω at +5V - ensures minimal signal attenuation and gain error in sensor front-ends and audio paths |
| On-Resistance Match | ≤8Ω at +5V - maintains channel-to-channel amplitude consistency in multi-path signal routing |
| Off-Leakage Current | 2nA max at +25°C - preserves accuracy in high-impedance measurement nodes and sample-hold circuits |
| Logic Thresholds | 0.8V low / 2.4V high at +5V - guarantees reliable digital control from standard microcontroller GPIOs |
| Crosstalk | –74dB at 1MHz - suppresses inter-channel interference in simultaneous multi-signal acquisition |
| Charge Injection | 5pC max - limits voltage glitch on sampled nodes, reducing need for post-switching settling delay |
Pinout & Package
MAX4524EUB+T uses the 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), with exposed pad connected to V+ per Maxim's recommended thermal layout. Pin functions are validated per datasheet Figure 1 (top view) and Pin Description table.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NO0 | Analog input/output channel 0 | Bidirectional path selected when ADDA=0, ADDB=0; must remain within V+ and GND |
| 2 NO1 | Analog input/output channel 1 | Bidirectional path selected when ADDA=1, ADDB=0; shares same RON and leakage specs as NO0 |
| 3 NO2 | Analog input/output channel 2 | Bidirectional path selected when ADDA=0, ADDB=1; fully interchangeable with NO0–NO3 |
| 4 NO3 | Analog input/output channel 3 | Bidirectional path selected when ADDA=1, ADDB=1; no internal priority or sequencing |
| 5 INH | Digital inhibit control | Pull high (>2.4V) to force all switches OFF; pull low (<0.8V) for normal operation |
| 6 ADDA | Address bit A | LSB of 2-bit binary select code; synchronous with ADDB for deterministic channel selection |
| 7 ADDB | Address bit B | MSB of 2-bit binary select code; both ADDA and ADDB must be stable before switching |
| 8 GND | Digital/analog reference ground | Return for logic circuitry and ESD diode bias; no analog signal reference - signals float between V+ and GND |
| 9 COM | Common analog terminal | Shared I/O node for all four channels; bidirectional and rail-to-rail capable |
| 10 V+ | Positive supply | Power for analog switches and logic translators; exposed pad must be soldered to PCB V+ plane for thermal reliability |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports full V+ to GND swing on all NOx/COM pins - eliminates external level-shifting in mixed-supply systems |
| Guaranteed on-resistance match | ≤8Ω variation across channels at +5V - enables precise ratio-metric measurements in multi-channel sensor arrays |
| TTL/CMOS logic compatibility | 0.8V/2.4V thresholds at +5V - allows direct interface with 3.3V or 5V microcontrollers without external buffers |
| Low off-leakage current | 2nA max at +25°C - minimizes error in high-Z applications like piezoelectric sensor conditioning or pH probe interfaces |
| Break-before-make switching | 400ns typical tBBM at +3V - prevents momentary shorting during channel transitions, protecting downstream amplifiers |

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 die, TDFN-EP (3mm × 3mm) package with exposed pad tied to V+; identical electrical specs and timing | Better thermal performance (1951mW dissipation vs. 330mW) and smaller footprint - preferred for space-constrained or high-density layouts | Select MAX4524ETB+ when PCB area or thermal management is critical; MAX4524EUB+T remains optimal for legacy µMAX-compatible designs. |
| TMUX1134RSVR | 4-channel mux with 1.5Ω typical RON at 3.3V, but only rated for –40°C to +125°C; no inhibit pin; higher supply current (1µA vs. 10nA) | Superior on-resistance for ultra-low-loss applications, but lacks global disable and operates at higher quiescent power | Choose TMUX1134RSVR only if sub-2Ω RON justifies loss of INH functionality and increased supply load in high-precision, wide-temp industrial use. |
Compared with MAX4524ETB+, the MAX4524EUB+T offers identical switching performance in a mature µMAX package with proven board-level reliability, while TMUX1134RSVR trades inhibit control and ultra-low leakage for lower on-resistance - making MAX4524EUB+T the balanced choice for battery-operated, temperature-stable multiplexing where global disable and low standby current are essential.

FAQ
What is the operating temperature range of the MAX4524EUB+T?
The MAX4524EUB+T is specified for operation from –40°C to +85°C, as confirmed in the Ordering Information table and Absolute Maximum Ratings section. This extended industrial temperature range makes it suitable for deployment in outdoor instrumentation, automotive cabin electronics, and portable medical devices where ambient conditions vary widely. The device's leakage and on-resistance parameters are guaranteed across this full range.
Does the MAX4524EUB+T support bidirectional analog signal flow?
Yes, the MAX4524EUB+T supports fully bidirectional analog signal flow on all NO0–NO3 and COM pins. As stated in the Pin Description note: "NO_, NC_, and COM_ analog signal pins are identical and interchangeable. Any may be considered an input or output; signals pass equally well in both directions." This enables flexible routing in both source-to-load and load-to-source configurations without polarity constraints.
How does the INH pin function on the MAX4524EUB+T?
The INH (inhibit) pin on the MAX4524EUB+T provides global disable: when driven high (>2.4V at +5V supply), it simultaneously opens all four analog paths (NO0–NO3 to COM), placing them in high-impedance off-state regardless of ADDA/ADDB logic levels. When pulled low (<0.8V), normal address-controlled switching resumes. This feature enables fast system-level signal isolation during fault conditions or power sequencing.
What is the maximum analog signal voltage the MAX4524EUB+T can handle?
The MAX4524EUB+T supports rail-to-rail analog signals from GND to V+. Per the Electrical Characteristics table, the analog signal range is specified as "V– to V+" (with V– = GND), meaning signals on NO0–NO3 and COM may swing continuously between 0V and the applied V+ supply voltage - up to +12V maximum - without damage or distortion, provided they do not exceed the Absolute Maximum Rating of (V+ + 0.3V).
Is the MAX4524EUB+T pin-compatible with other variants in the MAX4524 family?
Yes, the MAX4524EUB+T is pin-compatible with all 10-pin µMAX variants in the MAX4524 family, including MAX4524CUB and MAX4524EUB (without +T suffix). All share identical pinout, footprint, and electrical interface. The "+T" denotes tape-and-reel packaging, and "E" denotes the –40°C to +85°C temperature grade - mechanical and functional compatibility is maintained across these orderable variants.
