Product details
Overview
MAX4524CUB+T from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer/demultiplexer IC with TTL/CMOS-compatible digital control, 200Ω on-resistance at +5V, rail-to-rail signal handling, and an inhibit input that simultaneously opens all channels. It serves as a precision signal routing switch in battery-powered data-acquisition systems.
For engineers reviewing the MAX4524CUB+T datasheet, MAX4524CUB+T pinout, MAX4524CUB+T application, or MAX4524CUB+T equivalent, key selection criteria include on-resistance matching (≤8Ω), off-leakage current (≤2nA at +25°C), inhibit-controlled channel shutdown timing (tON/tOFF ≤200ns), and compatibility with +2V to +12V single-supply operation.
Technical Context
The MAX4524CUB+T implements four independent bidirectional analog switches controlled by two address bits (ADDA, ADDB) and a global inhibit (INH). Its CMOS architecture uses internal level translators to drive analog switch gates directly from logic-level inputs without requiring dual supplies.
All analog terminals (COM, NO0–NO3) support rail-to-rail voltage swing from GND to V+, with ESD protection diodes connected between each signal pin and both V+ and GND. On-resistance varies with supply voltage (200Ω @ +5V, 500Ω @ +3V) and analog common voltage (VCOM), exhibiting flatness of ≤12Ω over full signal range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | +2V to +12V single supply - enables direct integration into 3.3V and 5V systems without level-shifting circuitry |
| On-Resistance (V+ = +5V) | 200Ω typical - ensures minimal signal attenuation and gain error in precision analog paths |
| On-Resistance Match | ≤8Ω max - guarantees consistent channel-to-channel gain and phase response in multi-path routing |
| Off-Leakage Current | ≤2nA at +25°C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| Inhibit Turn-On/Off Time | ≤200ns - supports fast system-level power gating and dynamic reconfiguration |
| Logic Thresholds | 0.8V to 2.4V - ensures reliable TTL/CMOS compatibility with +5V supply without external biasing |
| Analog Signal Range | Rail-to-rail (GND to V+) - allows full utilization of ADC/DAC dynamic range without clipping |
Pinout & Package
MAX4524CUB+T is housed in a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch) with exposed pad for thermal enhancement. Pin 10 is V+, pin 5 is GND, and pin 4 is INH.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO0) | Analog switch normally open input 0 | Bidirectional signal path; connects to COM when ADDA=0, ADDB=0 |
| 2 (NO1) | Analog switch normally open input 1 | Bidirectional signal path; connects to COM when ADDA=1, ADDB=0 |
| 3 (NO2) | Analog switch normally open input 2 | Bidirectional signal path; connects to COM when ADDA=0, ADDB=1 |
| 4 (INH) | Inhibit control input | Active-high logic; forces all switches open regardless of address state |
| 5 (GND) | Digital/analog ground reference | Return path for internal logic and ESD diodes; no analog signal reference |
| 6 (ADDA) | Address bit A | LSB of 2-bit binary select code for channel routing |
| 7 (ADDB) | Address bit B | MSB of 2-bit binary select code for channel routing |
| 8 (NO3) | Analog switch normally open input 3 | Bidirectional signal path; connects to COM when ADDA=1, ADDB=1 |
| 9 (COM) | Analog common terminal | Shared I/O node; routes selected NOx signal bidirectionally |
| 10 (V+) | Positive supply | Powers analog switches and internal logic; also connects to exposed pad |
Key Features
| Feature | Design Value |
|---|---|
| Tiny 10-pin µMAX package | 3mm × 3mm footprint with exposed pad - reduces PCB area and improves thermal performance in space-constrained portable designs |
| Guaranteed on-resistance match | ≤8Ω max at +5V - eliminates inter-channel gain mismatch in multi-sensor data acquisition |
| Rail-to-rail analog signal handling | GND to V+ range - avoids signal clipping when interfacing with modern low-voltage ADCs and DACs |
| Low charge injection | ≤5pC - minimizes voltage glitch on sampled nodes in precision hold circuits |
| Break-before-make switching | ≥5ns guaranteed - prevents momentary shorting between channels during address transitions |

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; same electrical specs; exposed pad improves thermal dissipation | Better suited for high-density layouts requiring lower junction-to-board thermal resistance | Select MAX4524ETB+ when operating ambient exceeds +70°C or power dissipation >150mW |
| ADG1404BRUZ | 4-channel mux with 4.7Ω on-resistance (lower), but requires dual ±15V or single +30V supply; no inhibit pin | Higher precision but incompatible with low-voltage battery systems; lacks global shutdown | Choose ADG1404BRUZ only for industrial test equipment needing sub-5Ω RON and wide signal range |
Compared with MAX4524ETB+, the MAX4524CUB+T offers identical functionality in a legacy µMAX package optimized for established designs and hand-soldering; compared with ADG1404BRUZ, it trades lower on-resistance for single +2V to +12V operation and integrated inhibit control-critical for portable and safety-critical power-gated systems.

FAQ
What is the maximum supply voltage rating for MAX4524CUB+T?
The absolute maximum supply voltage for MAX4524CUB+T is +13V, though its specified operational range is +2V to +12V. Operation above +12V risks permanent damage, and the device is characterized and guaranteed only within the +2V to +12V range. At +12V, on-resistance drops to ~130Ω, but total harmonic distortion increases slightly compared to +5V operation.
Does MAX4524CUB+T support bidirectional signal flow?
Yes, MAX4524CUB+T supports fully bidirectional analog signal flow. All analog pins (COM, NO0–NO3) are symmetrical and interchangeable - either side can serve as input or output. This enables flexible routing in both source-to-load and load-to-source configurations without polarity constraints, essential for applications like sensor excitation and return path switching.
How does the INH pin function in MAX4524CUB+T?
The INH (inhibit) pin on MAX4524CUB+T is an active-high control that forces all four analog switches into the open (off) state regardless of ADDA/ADDB address states. When INH = logic high (≥2.4V at +5V supply), all channels disconnect; when INH = logic low (≤0.8V), normal address-controlled switching resumes. This provides hardware-level channel isolation for safety or power-saving modes.
What is the on-resistance flatness specification for MAX4524CUB+T?
MAX4524CUB+T guarantees ≤12Ω on-resistance flatness (RFLAT) over the full analog signal range (GND to V+) at +5V supply. Flatness is defined as the difference between maximum and minimum on-resistance measured across VCOM = 0V to V+, ensuring minimal distortion and amplitude variation for AC signals spanning the entire supply rail.
Is MAX4524CUB+T compatible with 3.3V logic systems?
Yes, MAX4524CUB+T is compatible with 3.3V logic systems when operated from a +3.3V supply. Its logic thresholds are specified as VIL ≤1.0V and VIH ≥2.0V at +3.3V, ensuring robust noise margins with standard 3.3V CMOS outputs. Address and inhibit inputs draw <1µA, imposing negligible loading on driving GPIOs.
