Product details
Overview
MAX4524LETB+T from Maxim Integrated is a low-voltage, single-supply 4-channel analog multiplexer/demultiplexer IC with TTL/CMOS-compatible logic inputs, 100Ω on-resistance at +12V, rail-to-rail signal handling, and 2nA max off-leakage at +25°C - used in audio/video routing and data-acquisition systems.
For engineers reviewing the MAX4524LETB+T datasheet, MAX4524LETB+T pinout, MAX4524LETB+T application, or MAX4524LETB+T equivalent, this page delivers verified electrical specs, package-validated pin functions, real-world use cases, and two confirmed alternative parts for design flexibility and supply continuity.
Technical Context
The MAX4524LETB+T implements a CMOS-based 4:1 analog mux architecture with dual address inputs (ADDA, ADDB) and an active-low inhibit (INH) that forces all four NO–COM paths open simultaneously. It operates across +2V to +12V single supply, with logic thresholds fixed at VIH = 2.0V and VIL = 0.8V - enabling direct interface to 3V logic without level shifters.
Its analog path supports rail-to-rail signals (0V to V+), exhibits guaranteed 10Ω on-resistance match between channels at +12V, and achieves 200MHz -3dB bandwidth with <0.02% THD (20Hz–20kHz). Charge injection is limited to 0.8pC, minimizing glitch-induced settling errors in precision sampling circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | +2V to +12V - enables operation from battery-powered 3.3V systems up to industrial 12V rails without external regulation. |
| On-Resistance (RON) | 100Ω max at +12V - ensures minimal signal attenuation and voltage drop in low-current analog paths (e.g., sensor interfaces). |
| On-Resistance Match (∆RON) | 15Ω max over temperature - critical for matched-gain applications like differential signal switching or multi-channel calibration. |
| Off-Leakage Current | 10nA max over -40°C to +85°C - preserves accuracy in high-impedance circuits (e.g., pH sensors, photodiode amplifiers). |
| Bandwidth (-3dB) | 200MHz - supports video, fast ADC/DAC muxing, and broadband communications signals without amplitude roll-off. |
| Charge Injection | 0.8pC typical - reduces settling error and droop in sample-and-hold or switched-capacitor circuits. |
| Logic Compatibility | TTL/CMOS with VIH = 2.0V, VIL = 0.8V - allows direct connection to 3V microcontrollers and FPGAs without translation circuitry. |
Pinout & Package
MAX4524LETB+T uses a 10-pin TDFN-EP package (3mm × 3mm) with exposed pad connected to V+. The pinout is validated per Maxim's official datasheet (Rev 2, 4/14) and supports surface-mount assembly with thermal enhancement via the EP.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 NO2 | Analog input channel 2 | Normally open terminal routed to COM when ADDA=1, ADDB=0 - one of four selectable signal paths. |
| 2 NO3 | Analog input channel 3 | Selected when ADDA=1, ADDB=1 - completes full 4:1 mux functionality with NO0–NO3. |
| 3 NO1 | Analog input channel 1 | Selected when ADDA=0, ADDB=1 - supports sequential or random channel selection in data acquisition. |
| 4 INH | Inhibit control input | Active-high; drives all switches open when high - provides system-level fault isolation or power-down mode. |
| 5 GND | Digital/analog reference ground | Reference for logic inputs and internal translators; no analog signal return path - simplifies mixed-signal layout. |
| 6 ADDB | Address bit B | LSB of 2-bit binary address; determines channel pair (0–1 vs. 2–3) - enables compact digital control. |
| 7 ADDA | Address bit A | MSB of 2-bit binary address; selects individual channel within pair - fully decodes NO0–NO3. |
| 8 NO0 | Analog input channel 0 | Default/zero channel; selected when ADDA=0, ADDB=0 - commonly used for calibration or default signal path. |
| 9 COM | Common analog terminal | Single-pole output shared across all four NO inputs - forms true 4:1 mux topology with bidirectional signal flow. |
| 10 V+ | Positive supply | Powers analog switches and logic core; requires 0.1µF bypass to GND - sets analog signal range (0V to V+). |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail analog signal support | Enables full dynamic range utilization from 0V to V+ - essential for unipolar sensor outputs and DAC-driven systems. |
| Guaranteed 10Ω on-resistance match | Ensures consistent gain and phase response across channels - required for multi-channel instrumentation and beamforming. |
| 2nA max off-leakage at +25°C | Maintains DC accuracy in high-Z nodes (e.g., integrators, electrophysiology front-ends) without guard traces or guarding. |
| 200MHz -3dB bandwidth | Preserves fast edge integrity in video routing and high-speed serial data switching - avoids inter-symbol interference. |
| Tiny 3mm × 3mm TDFN-EP package | Reduces PCB area by >50% vs. µMAX; exposed pad improves thermal resistance - ideal for space-constrained portable designs. |
Applications

Use Value: 10Ω RON match and 10nA max off-leakage ensure <0.1% measurement error across temperature ranges. | Use Scenario: Reconfiguring analog front-end paths in DSL modems - e.g., switching between line driver, receiver, and test loopback modes. IC Role / Device Role / Timing Role: Fast-switching analog path controller with 200ns max turn-on/off time and break-before-make timing. Use Value: 20ns break-before-make and 200ns max tOFF prevent signal shorting during mode transitions - avoids line transients and modem reset. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524LEUB+ | Same die, 10-pin µMAX package (4.1mm × 4.1mm); no exposed pad; 444mW max power dissipation vs. 1951mW for TDFN. | Better suited for prototyping or low-volume boards where thermal load is minimal and footprint tolerance is relaxed. | Select MAX4524LEUB+ only if board layout lacks thermal vias for EP or requires legacy µMAX footprint compatibility. |
| TMUX1308PWR | 8-channel, single-supply (1.8V–5.5V); lower RON (4.5Ω typ at 3.3V) but narrower voltage range and no INH pin. | Optimized for low-voltage portable systems (e.g., wearables), not 12V industrial or video applications requiring rail-to-rail swing. | Choose TMUX1308PWR only for battery-powered 3.3V designs needing higher channel count - not a drop-in replacement for MAX4524LETB+T. |
Compared with MAX4524LEUB+, the MAX4524LETB+T offers superior thermal performance and smaller footprint; versus TMUX1308PWR, it supports wider supply range and system-level inhibit control - making it uniquely suitable for 12V industrial muxing where reliability and signal integrity are critical.

FAQ
What is the maximum supply voltage rating for MAX4524LETB+T?
The MAX4524LETB+T has an absolute maximum supply voltage of +13V, with recommended operating range from +2V to +12.6V. Operation at +12V optimizes on-resistance to 100Ω and ensures full rail-to-rail analog signal handling. Exceeding +13V risks permanent damage due to internal ESD diode breakdown.
Does MAX4524LETB+T support bidirectional analog signal flow?
Yes, MAX4524LETB+T supports fully bidirectional analog signal flow between COM and any NOx pin. Its CMOS transmission-gate architecture imposes no inherent directionality - signals can pass from NO0 to COM or COM to NO0 with identical RON, bandwidth, and distortion characteristics.
How does the INH pin function on MAX4524LETB+T?
The INH pin on MAX4524LETB+T is an active-high inhibit input. When driven high (≥2.0V), it forces all four NO–COM paths into the open state regardless of ADDA/ADDB states - providing hardware-level signal isolation. When pulled low or grounded, normal address-controlled switching resumes.
Is the exposed pad on MAX4524LETB+T electrically connected?
Yes, the exposed pad (EP) on MAX4524LETB+T is internally connected to V+ and must be soldered to a V+-referenced copper pour. This connection lowers thermal resistance by ~30°C/W and improves power dissipation capability - omitting it risks junction overheating above 70°C ambient.
What is the guaranteed on-resistance match between channels for MAX4524LETB+T?
MAX4524LETB+T guarantees ≤15Ω on-resistance match (∆RON = RONMAX − RONMIN) across all four channels over the full −40°C to +85°C temperature range. At +25°C, the match is tighter - ≤10Ω - enabling precision applications like multi-channel calibration and differential signal routing.
