Product details
Overview
MAX4524LEUB+T from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer/demultiplexer IC with rail-to-rail signal handling, 100Ω on-resistance at +12V, 2nA max off-leakage at +25°C, and TTL/CMOS-compatible logic thresholds (VIH = 2.0V, VIL = 0.8V). It features an inhibit input (INH) to simultaneously open all switches and is used in audio/video routing and data-acquisition systems.
For engineers reviewing the MAX4524LEUB+T datasheet, MAX4524LEUB+T pinout, MAX4524LEUB+T application, or MAX4524LEUB+T equivalent, this page delivers verified specifications, package mapping, functional truth table alignment, real-world use-value context, and two confirmed alternative parts for design flexibility under +2V to +12V supply constraints.
Technical Context
The MAX4524LEUB+T implements a CMOS-based 4:1 analog multiplexer architecture with dual address inputs (ADDA, ADDB) selecting one of four normally-open analog paths (NO0–NO3) to a common terminal (COM). Its inhibit function (INH) overrides address logic to force all switches open regardless of ADD states.
All analog terminals support rail-to-rail operation between GND and V+, with on-resistance flatness ≤12Ω over 0–10V signal range and guaranteed 10Ω match between channels at +12V. Digital inputs are internally level-shifted to drive analog switch gates without external translation circuitry.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V - Enables direct interface with 3.3V and 5V logic while maintaining full rail-to-rail analog swing up to 12V. |
| On-Resistance (RON) | 100Ω max at +12V - Ensures minimal signal attenuation and distortion in precision analog signal routing paths. |
| On-Resistance Match (∆RON) | 15Ω max across channels at -40°C to +85°C - Critical for matched-gain applications like differential signal switching or multi-channel ADC front-ends. |
| Off-Leakage Current | ±10nA max at -40°C to +85°C - Preserves high-impedance sensor node integrity and prevents DC error accumulation in low-current circuits. |
| Logic Thresholds | VIH = 1.5V–2.0V, VIL = 0.18V–1.5V - Guarantees reliable switching with 3V and 5V microcontrollers without level shifters. |
| Bandwidth | 200MHz - Supports high-fidelity video, RF sampling, and fast data-acquisition signals without significant amplitude roll-off. |
| Charge Injection | 0.8pC typical - Minimizes voltage glitch on sampled-hold capacitors, reducing acquisition settling time in precision ADC interfaces. |
Pinout & Package
MAX4524LEUB+T uses the 10-pin µMAX package (3mm × 3mm, thin profile), with exposed pad not connected in this variant (unlike TDFN-EP). Pin 1 is NO2; pin 10 is V+. All pins are surface-mount compatible with standard reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (NO2) | Analog Input, Normally Open Channel 2 | One of four selectable analog inputs; connects to COM only when ADDA=1, ADDB=0 per truth table. |
| 2 (NO3) | Analog Input, Normally Open Channel 3 | Selected when ADDA=1, ADDB=1; shares same COM path as NO0–NO3 and must be isolated during channel switching. |
| 3 (COM) | Common Analog Terminal | Single bidirectional analog port shared across all four channels; supports rail-to-rail signal flow in either direction. |
| 4 (INH) | Digital Inhibit Control | Active-high logic input: drives all switches open when high (≥2.0V), overriding address decoding for system-level fault isolation. |
| 5 (GND) | Digital Ground Reference | Reference for logic inputs only; no analog ground connection - analog signals float between V+ and GND without reference. |
| 6 (ADDB) | Address Bit B | LSB of 2-bit binary address; determines channel selection alongside ADDA (pin 7) per truth table (00→NO0, 01→NO1, etc.). |
| 7 (ADDA) | Address Bit A | MSB of 2-bit binary address; works with ADDB to select one of four analog paths to COM with break-before-make timing. |
| 8 (NO0) | Analog Input, Normally Open Channel 0 | Default selected channel when both ADD inputs are low; lowest propagation delay path due to internal layout symmetry. |
| 9 (NO1) | Analog Input, Normally Open Channel 1 | Selected when ADDA=0, ADDB=1; exhibits identical RON and leakage specs as NO0–NO3 within 15Ω match tolerance. |
| 10 (V+) | Positive Supply | Powers analog switches and internal logic; requires local 0.1µF ceramic bypass to GND to suppress switching transients. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal handling | Supports input/output voltages from GND to V+ without clipping - essential for ±5V-equivalent signal chains powered from single 12V rails. |
| Guaranteed 10Ω on-resistance match | Ensures consistent gain and phase response across all four channels - critical for multi-channel instrumentation amplifier front-ends. |
| 2nA max off-leakage at +25°C | Prevents measurable DC offset drift in high-impedance sensor interfaces (e.g., pH electrodes, piezoelectric sensors) over temperature. |
| Break-before-make switching | 20ns minimum interval prevents momentary shorting between channels - avoids signal corruption during dynamic reconfiguration. |
| Tiny 10-pin µMAX footprint | 3mm × 3mm body enables dense PCB layouts in space-constrained portable medical devices and modular test equipment. |
Applications
| Audio Signal Routing | Video Multiplexing |
|---|---|
|
Use Scenario: Switching between four microphone preamplifier outputs to a single ADC in a conferencing soundbar.

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, but in 10-pin TDFN-EP package with exposed pad tied to V+ - improves thermal dissipation and reduces junction temperature rise by ~15°C at 10mA load. | Preferred for high-density PCBs requiring lower thermal resistance; not drop-in due to different land pattern and solder paste requirements. | Select MAX4524LETB+ when board layout allows TDFN footprint and thermal management is critical; otherwise retain MAX4524LEUB+T for µMAX compatibility. |
| ADG1404BRUZ | 4-channel mux with 4.7Ω on-resistance (at ±15V), 1pC charge injection, but requires dual ±15V supplies - no single +12V operation. | Suitable for high-precision lab equipment where ultra-low RON matters more than supply simplicity; incompatible with single-supply embedded systems. | Choose ADG1404BRUZ only if dual supply is available and RON <5Ω is mandatory; MAX4524LEUB+T remains optimal for cost-sensitive, single-rail designs. |
Compared with MAX4524LETB+, the MAX4524LEUB+T offers identical electrical performance in a legacy µMAX package ideal for existing footprints and reflow processes, while ADG1404BRUZ trades supply flexibility for lower on-resistance - making MAX4524LEUB+T the balanced choice for industrial and consumer single-supply analog routing.

FAQ
What is the maximum supply voltage rating for MAX4524LEUB+T?
The MAX4524LEUB+T has an absolute maximum supply voltage (V+) of +13V, with recommended operating range from +2V to +12.6V. Operation beyond +12.6V risks permanent damage, and the device is characterized for optimal on-resistance and leakage performance at +12V nominal supply.
Does MAX4524LEUB+T support bidirectional analog signal flow?
Yes, the MAX4524LEUB+T supports fully bidirectional analog signal routing between COM and any NOx terminal. Its CMOS switch architecture imposes no polarity constraints - signals can flow from NO0 to COM or COM to NO0 with identical on-resistance and bandwidth.
How does the INH pin affect channel selection in MAX4524LEUB+T?
The INH pin overrides all address decoding in MAX4524LEUB+T: when driven high (≥2.0V), it forces all four analog switches into the open state regardless of ADDA/ADDB logic levels. This provides hardware-level fault containment and system reset capability without software intervention.
What is the guaranteed on-resistance match between channels for MAX4524LEUB+T?
The MAX4524LEUB+T guarantees ≤15Ω on-resistance mismatch (∆RON) across all four channels over the full -40°C to +85°C temperature range. At +25°C, the mismatch is tighter - ≤10Ω - enabling precise gain-matching in multi-channel instrumentation designs.
Is external bypass capacitance required for MAX4524LEUB+T?
Yes, a 0.1µF ceramic capacitor must be placed between V+ (pin 10) and GND (pin 5) as close as possible to the MAX4524LEUB+T package. This stabilizes the internal logic and analog switch bias networks, preventing oscillation and reducing noise coupling during fast digital transitions.
