Product details
Overview
The MAX4534EPD from Maxim Integrated is a fault-protected, single 4-to-1 analog multiplexer designed for high-voltage signal routing in harsh environments. It operates from ±4.5V to ±20V dual supplies or +9V to +36V single supply, delivers ≤400Ω on-resistance, ±40V fault protection with supplies off, and rail-to-rail signal handling - enabling robust data acquisition in industrial control and avionics systems.
For engineers reviewing the MAX4534EPD datasheet, MAX4534EPD pinout, MAX4534EPD application, or MAX4534EPD equivalent, this device supports critical fault-tolerant switching where overvoltage transients, supply sequencing independence, and precise channel matching (≤10Ω RON mismatch) are mandatory design requirements.
Technical Context
The MAX4534EPD uses parallel N- and P-channel FETs per switch path to achieve low on-resistance and true rail-to-rail signal conduction. Its dual comparator-based fault detection clamps COM output to V+ or V− within 20ns when NO inputs exceed rails by ~150mV, while maintaining high-impedance isolation on NO pins during fault conditions.
Fault response is supply-agnostic: ±40V protection applies with supplies off; ±25V protection applies with ±15V supplies on. All digital inputs feature TTL/CMOS thresholds (0.8V low / 2.4V high), eliminating external level-shifting when used with +12V or ±15V logic systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Range | ±4.5V to ±20V dual or +9V to +36V single - supports wide industrial and avionic power architectures without regulation. |
| On-Resistance (max) | 400Ω - ensures minimal signal attenuation and thermal drift in precision sensor and DAC/ADC interface paths. |
| RON Match (max) | 10Ω between channels - enables accurate ratiometric measurements and matched gain paths in multi-channel systems. |
| Fault Protection | ±40V with supplies off; ±25V with ±15V supplies on - protects downstream circuitry from transient overvoltages without external components. |
| Fault Response Time | 20ns typical - limits fault energy injection into sensitive analog front-ends during fast transients. |
| Logic Compatibility | TTL/CMOS thresholds (0.8V/2.4V) - interoperates directly with standard microcontroller GPIOs and FPGA I/O banks. |
| Operating Temp | –40°C to +85°C - qualified for extended industrial and avionic environmental stress profiles. |
Pinout & Package
MAX4534EPD is housed in a 14-pin plastic DIP package with through-hole mounting and 0.3-inch width. Pin layout follows industry-standard SO/DIP/TSSOP footprints for drop-in compatibility across package variants.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 14 | A0, A1 | Binary address inputs selecting one of four NOx inputs to route to COM; CMOS/TTL compatible. |
| 2 | EN | Active-high enable controlling all switch paths; high-impedance state when low. |
| 3 | V− | Negative supply rail; must be connected for dual-supply operation or grounded for single-supply mode. |
| 4, 5, 10, 11 | NO1–NO4 | Fault-protected analog inputs; withstand ±40V with supplies off, clamp COM during overvoltage. |
| 7 | COM | Analog output common node; not fault-protected - must remain within V− to V+ during operation. |
| 12 | V+ | Positive supply rail; powers internal logic and switch drivers; sets logic threshold reference. |
| 13 | GND | Digital ground reference for logic inputs; internally isolated from analog signal paths. |
| 6, 8, 9 | N.C. | No internal connection; left unconnected per datasheet; no routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Passes signals from V− to V+ without clipping - preserves full dynamic range of ±10V sensors and DAC outputs. |
| No supply sequencing required | Operates safely regardless of V+ / V− / EN power-up order - eliminates complex power management in multi-rail systems. |
| All channels off with power off | NOx pins become high-impedance open circuits when V+ and V− = 0 - prevents backfeeding or latch-up in powered-down subsystems. |
| Output clamping during fault | COM is actively clamped to V+ or V− during overvoltage - protects downstream ADCs, op-amps, or microcontroller inputs. |
| 1.0kΩ typical clamp resistance | Limits fault current to ≤10mA at ±25V overvoltage - avoids tripping upstream fuses or damaging supply rails. |
Applications
| Data-Acquisition Systems | Industrial Process Control |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar fault-protected analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4534ESD | TSSOP-14 package; identical electrical specs and fault behavior; 2.1mm × 5mm footprint vs. DIP's 7.62mm pitch. | Better suited for space-constrained PCBs; requires reflow assembly vs. through-hole soldering. | Select MAX4534ESD when board real estate is limited and automated SMT assembly is available. |
| ADG508FBRZ | Single 8-to-1 mux; ±15V rating only; ±40V fault protection with supplies off; 450Ω max RON; no rail-to-rail signal handling. | Supports more inputs but lacks true rail-to-rail conduction and has higher on-resistance mismatch (25Ω). | Choose ADG508FBRZ only when 8-channel density outweighs need for sub-400Ω RON and full rail compliance. |
Compared with MAX4534ESD, the MAX4534EPD offers mechanical robustness and hand-solderability at the cost of larger footprint; versus ADG508FBRZ, it delivers superior signal fidelity and fault resilience in 4-channel systems where precision and transient immunity are prioritized over channel count.

FAQ
What is the maximum allowable voltage on NO pins for MAX4534EPD when supplies are off?
The MAX4534EPD guarantees ±40V fault protection on NO1–NO4 pins with V+ and V− disconnected. This allows safe connection to unpowered circuits or floating sensor lines up to ±40V relative to ground without damage. Exceeding this limit risks permanent ESD structure failure, as confirmed in Absolute Maximum Ratings Table.
Does MAX4534EPD support rail-to-rail signal operation with single-supply configuration?
Yes, the MAX4534EPD supports rail-to-rail signal handling from V− to V+ in both dual-supply (±4.5V to ±20V) and single-supply (+9V to +36V, with V− = GND) modes. The internal parallel FET architecture ensures full conduction across the entire supply range, verified in Typical Operating Characteristics Figure toc02.
How does fault protection behave on the COM pin of MAX4534EPD?
The COM pin of MAX4534EPD is explicitly not fault-protected. Per datasheet Note 1 and Detailed Description section, exceeding V− or V+ on COM risks forward-biasing internal ESD diodes and causing destructive current flow. Users must ensure COM remains within supply rails - unlike NOx pins, which tolerate ±40V faults.
What is the on-resistance matching specification for MAX4534EPD across its four channels?
The MAX4534EPD guarantees ≤10Ω maximum on-resistance mismatch (∆RON) between any two channels under specified conditions (V+ = +15V, V− = −15V, TA = +25°C). This tight matching enables high-accuracy ratiometric measurements in multi-sensor data acquisition systems, as documented in Electrical Characteristics Table.
Can MAX4534EPD operate with asymmetric dual supplies, such as +12V and −5V?
Yes, the MAX4534EPD supports asymmetric dual supplies as long as the absolute difference between V+ and V− does not exceed 44V and each rail stays within its Absolute Maximum Rating (V+ ≤ +44V, V− ≥ −44V). The device functions correctly with +12V/−5V, enabling flexible biasing in mixed-signal systems.
