Product details
Overview
The MAX4510EUT from Maxim Integrated is a fault-protected, normally closed (NC), single-pole/single-throw (SPST) analog switch designed for high-reliability signal routing in industrial and avionics systems. It delivers rail-to-rail signal handling with ±15V dual supplies, 160Ω max on-resistance, 0.5nA off-leakage at +25°C, and ±36V fault protection during operation - enabling robust operation in data acquisition and redundant backup systems.
For engineers reviewing the MAX4510EUT datasheet, MAX4510EUT pinout, MAX4510EUT application, or MAX4510EUT equivalent, key selection considerations include its NC logic state, SOT23-6 package footprint, fault-protection behavior under power-on/off conditions, and compatibility with ±4.5V to ±20V dual or +9V to +36V single-supply configurations.
Technical Context
The MAX4510EUT uses dual parallel FETs (N1 and P1) to achieve low on-resistance and true rail-to-rail conduction. Two independent comparators continuously monitor the NC pin voltage against V+ and V−, triggering fault response within nanoseconds when signals exceed supply rails by ~50mV.
During overvoltage faults, the NC terminal becomes high-impedance while internal "booster" FETs (P2/N2) source or sink up to ±13mA from V+/V− to the COM output - clamping it to the appropriate supply rail without glitching. Fault protection remains active with power removed, supporting ±40V fault tolerance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST analog switch - COM connects to NC when IN = 0V |
| On-Resistance (max) | 160Ω at ±15V supplies - ensures minimal signal attenuation in precision analog paths |
| Fault Protection | ±36V with power applied; ±40V with power off - protects downstream circuitry without external components |
| Off-Leakage Current | 0.5nA at +25°C - preserves signal integrity in high-impedance sensor interfaces |
| Supply Range | ±4.5V to ±20V dual or +9V to +36V single - supports wide industrial and avionics input voltages |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) at ±15V or +12V - eliminates level-shifter requirements |
| Turn-On/Off Time | 60ns/175ns typical (±15V, RL=2kΩ, CL=35pF) - suitable for medium-speed multiplexing |
Pinout & Package
MAX4510EUT is housed in a 6-pin SOT23-6 package (JEDEC MO-178AA), with exposed pad not electrically connected. Pin 1 is V+, pin 2 is V−, pin 3 is IN, pin 4 is GND, pin 5 is COM, and pin 6 is NC (normally closed terminal).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| V+ | Positive supply input | Provides power for internal logic and gate drive; sets high-threshold logic level |
| V− | Negative supply input | Provides negative rail for dual-supply operation; connects to GND for single-supply use |
| IN | Digital control input | Active-low logic: IN = 0V enables NC–COM path; IN = high disables it |
| GND | Analog/digital reference | Reference for logic inputs and ESD diodes; no direct connection to analog signal path |
| COM | Common analog terminal | Signal output node; not fault-protected - must remain within V− to V+ range |
| NC | Fault-protected input | Normally closed analog input; withstands ±36V faults with power, ±40V with power off |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Passes signals from V− to V+ without clipping - essential for full-scale sensor or DAC outputs |
| Fault-induced open-circuit NC pin | NC terminal isolates at nanoamp leakage during overvoltage - prevents damage to upstream sources |
| Clamped COM output during fault | COM actively driven to V+ or V− (up to ±13mA) - maintains defined logic levels at load |
| No power-supply sequencing required | V+ and V− may be powered in any order - simplifies system power-up design |
| Low power consumption | <2mW typical - enables use in thermally constrained or battery-backed modules |
Applications
| Industrial Process Monitoring | Avionics Sensor Redundancy |
|---|---|
Use Scenario: Multiplexing multiple pressure/temperature transducer outputs into a shared ADC channel under harsh EMI and transient conditions. IC Role / Device Role / Timing Role: Fault-protected NC switch routes primary sensor signal; automatically isolates during wiring fault or lightning-induced surge.

IC Role / Device Role / Timing Role: SPST switch inserted in signal chain to enable/disable calibration reference injection or DUT stimulus. Use Value: Maintains signal fidelity across 1MHz bandwidth (−3dB) while providing 62dB off-isolation at 1MHz. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar fault-protected analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4520EUT | Identical architecture and specs, but normally open (NO) logic state - IN = 0V disconnects NC–COM path | Used where default-open safety state is required (e.g., emergency shutdown circuits) | Select MAX4520EUT when system requires de-energized default; MAX4510EUT for energized-default operation |
| ADG5412BRUZ | 4-channel, ±40V fault-protected SPST switch; higher on-resistance (30Ω typ); requires external fault flag monitoring | Supports multi-channel routing in compact 16-pin TSSOP; lacks integrated clamp current sourcing | Choose ADG5412BRUZ for multi-channel density; MAX4510EUT for single-channel simplicity and self-contained fault response |
Compared with MAX4520EUT and ADG5412BRUZ, the MAX4510EUT provides the only combination of NC default state, integrated ±13mA fault-current sourcing, and SOT23-6 footprint - making it optimal for space-constrained, single-path, fail-safe signal routing.

FAQ
What is the logic polarity of the MAX4510EUT control input?
The MAX4510EUT features active-low logic: when the IN pin is at 0V (or ≤0.8V), the NC–COM path is closed; when IN is at V+ (or ≥2.4V), the switch opens. This NC default state ensures signal continuity during power loss or controller reset - a critical safety feature in MAX4510EUT deployments.
Can the MAX4510EUT operate from a single +12V supply?
Yes, the MAX4510EUT supports single-supply operation from +9V to +36V. For +12V use, connect V− to GND. The device maintains 160Ω max on-resistance, ±36V fault protection, and TTL/CMOS-compatible logic thresholds - all verified in the MAX4510EUT electrical characteristics table under single-supply conditions.
Is the COM pin fault-protected on the MAX4510EUT?
No, the COM pin is not fault-protected on the MAX4510EUT. Only the NC pin has ±36V (power on) or ±40V (power off) fault tolerance. Exceeding V+ or V− at the COM pin forward-biases internal ESD diodes, risking permanent damage. System design must ensure COM remains within the supply rails at all times - a key constraint documented in the MAX4510EUT Absolute Maximum Ratings.
How does the MAX4510EUT respond during an overvoltage fault?
When the NC pin exceeds V+ or V− by ~50mV, the MAX4510EUT instantly disables the NC–COM path and presents >100MΩ impedance at NC. If the switch was previously closed, internal booster FETs drive COM to V+ (for positive faults) or V− (for negative faults) with up to ±13mA - ensuring clean rail clamping without transition glitches, as confirmed in the MAX4510EUT functional diagram and timing waveforms.
What package options are available for the MAX4510EUT?
The MAX4510EUT is specified exclusively in the 6-pin SOT23-6 package (ordering code suffix "EUT"). While the MAX4510 family also includes an 8-pin µMAX variant (MAX4510EUA), the MAX4510EUT designation refers only to the SOT23-6 version - verified in the Maxim ordering information table and top-marking legend (AADK).
