Product details
Overview
MAX4524EUB-TG068 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 operates from +2V to +12V and is widely used in battery-powered audio routing and low-voltage data-acquisition systems.
For engineers reviewing the MAX4524EUB-TG068 datasheet, MAX4524EUB-TG068 pinout, MAX4524EUB-TG068 application, or MAX4524EUB-TG068 equivalent, this device delivers precise channel selection, sub-2nA off-leakage at +25°C, guaranteed on-resistance matching (≤8Ω), and fast inhibit switching (tON/tOFF ≤ 200ns at +5V), making it suitable for precision analog signal routing where supply headroom and leakage integrity are critical.
Technical Context
The MAX4524EUB-TG068 implements a CMOS transmission-gate architecture with dual-level logic translators that convert TTL/CMOS inputs into full-rail gate drive signals-enabling rail-to-rail analog conduction without external level-shifting. Its internal ESD diodes clamp analog pins to V+ and GND, defining absolute signal limits and contributing to leakage behavior.
It features break-before-make switching (tBBM = 5ns typical), minimal charge injection (0.8–5pC), and flat on-resistance (RFLAT ≤ 12Ω) across its 0V–V+ analog range. The inhibit function overrides address decoding, forcing all four NO–COM paths open regardless of ADDA/ADDB state.
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 (V+ = +5V) | 200Ω max; ensures <1% gain error in 600Ω audio paths and supports 10-bit accuracy in 12-bit ADC front-ends. |
| On-Resistance Match | ≤8Ω between channels at +5V; minimizes crosstalk-induced amplitude mismatch in multi-channel sampling. |
| Off-Leakage Current | ≤2nA at +25°C; preserves high-impedance sensor node integrity and prevents DC offset drift in precision amplifiers. |
| Inhibit Turn-On/Off Time | 200ns max at +5V; allows synchronous channel blanking during ADC sampling windows or power-state transitions. |
| Analog Signal Range | Rail-to-rail (V– to V+); supports full-scale operation with unipolar 0–5V or bipolar ±2.5V signals without clipping. |
| Logic Thresholds | VIL ≤ 1.5V, VIH ≥ 2.4V at +5V; ensures robust noise margin and direct interface with standard 5V TTL/CMOS controllers. |
Pinout & Package
MAX4524EUB-TG068 uses a 10-pin µMAX package (3mm × 3mm, 0.5mm pitch), with exposed pad connected to V+. Pin functions are validated per Maxim's official datasheet Rev 2 (19-1332).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NO0 | Channel 0 normally open analog terminal; bidirectional path to COM when selected via ADDA/ADDB = 00. |
| 2 | NO1 | Channel 1 normally open analog terminal; active when ADDA/ADDB = 01; shares same RON and leakage specs as NO0. |
| 3 | NO2 | Channel 2 normally open analog terminal; selected at ADDA/ADDB = 10; matched RON ensures uniform gain across mux outputs. |
| 4 | NO3 | Channel 3 normally open analog terminal; activated at ADDA/ADDB = 11; fully interchangeable with NO0–NO2 in layout. |
| 5 | INH | Inhibit control input; logic-high forces all channels open regardless of address state-critical for system-safe shutdown. |
| 6 | ADDA | LSB address input; controls binary selection of one of four NO paths; compatible with 3.3V or 5V logic drivers. |
| 7 | ADDB | MSB address input; used with ADDA to decode 00–11; no internal pull-up/down-requires external termination. |
| 8 | GND | Digital/analog ground reference; all logic thresholds and ESD clamps referenced to this pin; must be low-impedance. |
| 9 | COM | Common analog terminal; bidirectional I/O port shared across all four channels; handles rail-to-rail signals up to V+. |
| 10 | V+ | Positive supply for analog switches and logic translators; powers internal CMOS gates and defines analog voltage ceiling. |
Key Features
| Feature | Design Value |
|---|---|
| Tiny 10-pin µMAX package | 3mm × 3mm footprint with exposed thermal pad-reduces PCB area by >40% vs. SOIC-16 while enabling high-density analog routing. |
| Guaranteed on-resistance match | ≤8Ω max difference between any two channels at +5V-eliminates inter-channel gain skew in simultaneous-sampling applications. |
| Sub-2nA off-leakage at +25°C | Preserves signal integrity in high-Z sensor interfaces (e.g., piezoelectric transducers, pH electrodes) without calibration drift. |
| Break-before-make timing | 5ns typical-prevents momentary shorting between channels during address transitions, avoiding signal glitches in audio/video paths. |
| Charge injection control | 0.8–5pC typical-limits voltage step errors (<1mV on 10nF hold capacitors), essential for sample-and-hold and switched-capacitor circuits. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4524EUB+ | RoHS-compliant (lead-free), identical electrical specs and µMAX package; top mark "U10+2". | No functional change; required for new designs targeting lead-free compliance or EU RoHS directives. | Select MAX4524EUB+ when environmental compliance or long-term supply continuity under RoHS mandates is prioritized. |
| ADG1404YRUZ | 4-channel mux with lower RON (4.7Ω typ), higher supply range (+5V to ±15V), but larger 16-lead TSSOP package and no inhibit pin. | Better performance in precision instrumentation, but requires PCB redesign and lacks hardware-level channel disable. | Choose ADG1404YRUZ only if sub-5Ω on-resistance justifies layout change and inhibit functionality is implemented externally. |
Compared with MAX4524EUB+, the MAX4524EUB-TG068 offers identical analog performance and pinout but lacks RoHS certification-making it suitable for legacy repair or non-regulated markets. Against ADG1404YRUZ, it trades lower RON and wider supply for smaller size, integrated inhibit, and lower cost in space-constrained battery-operated systems.

FAQ
What is the operating temperature range for the MAX4524EUB-TG068?
The MAX4524EUB-TG068 is rated for operation from -40°C to +85°C, as confirmed in the Ordering Information table and Absolute Maximum Ratings section of the official datasheet. This extended industrial temperature range makes it suitable for deployment in automotive cabin modules, outdoor instrumentation, and industrial control panels where ambient conditions exceed commercial-grade limits. The MAX4524EUB-TG068 maintains specified on-resistance, leakage, and timing parameters across this full range.
Does the MAX4524EUB-TG068 support rail-to-rail analog signals?
Yes, the MAX4524EUB-TG068 supports rail-to-rail analog signal operation-meaning it can pass signals from GND to V+ without clipping or distortion. This capability is explicitly stated in the General Description and verified in the Electrical Characteristics tables, where "Analog Signal Range" is defined as V– to V+ (i.e., 0V to V+). The internal CMOS transmission-gate structure and level-translated gate drive enable true bidirectional conduction across the full supply range.
What is the function of the INH pin on the MAX4524EUB-TG068?
The INH (inhibit) pin on the MAX4524EUB-TG068 provides hardware-level override control: when driven high (≥2.4V at +5V supply), it forces all four NO–COM channels into the open (off) state regardless of ADDA/ADDB address inputs. This feature enables rapid, glitch-free channel isolation during system reset, power sequencing, or fault conditions. The MAX4524EUB-TG068's inhibit turn-on/off times are specified at ≤200ns, ensuring tight synchronization with control logic.
Is the MAX4524EUB-TG068 pin-compatible with other variants in the MAX4524 family?
Yes, the MAX4524EUB-TG068 shares identical pinout and functionality with all 10-pin µMAX variants of the MAX4524, including MAX4524EUB, MAX4524EUB+, and MAX4524CUB. All use the same 10-pin µMAX package (drawing 21-0061I), identical pin numbering, and identical truth table behavior. Differences are limited to temperature grade, RoHS status, and top marking-ensuring drop-in replacement capability in existing layouts without modification.
What is the maximum on-resistance specification for the MAX4524EUB-TG068 at +3V supply?
At a +3V supply (V+ = 2.7V to 3.6V), the MAX4524EUB-TG068 has a maximum on-resistance (RON) of 500Ω, as specified in the Electrical Characteristics table for Single +3V Supply. This value is measured under standard conditions (VCOM = 1.5V, ICOM = 0.1mA) and reflects the expected increase in RON at lower supply voltages due to reduced gate overdrive. The MAX4524EUB-TG068 remains fully functional down to +2V, though RON rises further outside datasheet characterization limits.
