Product details
Overview
MAX4712EUE+ from Maxim Integrated is a fault-protected, quad SPST analog switch with normally open (NO) configuration, operating from +2.7V to +11V single supply or ±2.7V to ±5.5V dual supplies. It delivers 25Ω max on-resistance at +25°C, <125ns turn-on time, and ±12V fault protection on NO pins with power off - enabling robust signal routing in battery-powered test equipment and industrial control systems.
For engineers reviewing the MAX4712EUE+ datasheet, MAX4712EUE+ pinout, MAX4712EUE+ application, or MAX4712EUE+ equivalent, this page provides verified specifications, fault-protection behavior under overvoltage transients, rail-to-rail analog signal handling, and pin-compatible alternatives for high-reliability analog switching designs.
Technical Context
The MAX4712EUE+ uses parallel N- and P-channel FETs per channel to achieve low RON and flat on-resistance across the signal range. Its dual comparators continuously monitor NO pin voltage against V+ and V−, triggering clamp FETs (P2/N2) during fault conditions to limit COM output to the appropriate supply rail.
Fault response is asymmetric: positive faults clamp COM to V+, negative faults clamp to V−, with ~200ns fault turn-on delay and 700ns recovery time (dual supply). The COM pins lack fault protection and rely on internal ESD diodes - exceeding V+/V− by >0.7V risks excessive current flow.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RON) | 25Ω max at +25°C, +4.5V/–4.5V supplies - ensures minimal signal attenuation in precision analog paths. |
| RON Match Between Channels | 1Ω max - enables matched gain/attenuation in multi-channel instrumentation or differential signal routing. |
| Turn-On / Turn-Off Time | <125ns / <80ns - supports high-speed multiplexing up to ~3 MHz without timing skew. |
| Fault Protection Range | ±12V on NO pins with power off; ±7V with ±5V supplies - protects downstream circuitry from accidental overvoltage during maintenance or hot-swap. |
| Logic Compatibility | TTL/CMOS inputs (VIH = 2.4V, VIL = 0.8V) - interoperable with microcontrollers and FPGA I/O without level-shifting. |
| Supply Range | +2.7V to +11V (single); ±2.7V to ±5.5V (dual) - supports wide-input battery systems and legacy bipolar rails. |
| Operating Temperature | –40°C to +85°C - qualified for industrial and avionics environments with thermal cycling stress. |
Pinout & Package
MAX4712EUE+ is housed in a 16-pin TSSOP package (4.4mm × 5mm, 0.65mm pitch), RoHS-compliant and moisture-sensitive level 1.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Fault-protected logic inputs; accept VIH ≥2.4V (TTL/CMOS) and tolerate up to (V− +12V) - enable direct MCU/FPGA control with transient immunity. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals; not fault-protected - must remain within V− to V+ to avoid ESD diode conduction and damage. |
| 3, 6, 11, 14 | NO1–NO4 | Fault-protected normally open analog inputs; withstand ±12V faults with power off - serve as protected signal entry points in test fixtures. |
| 4 | V− | Negative supply input; connect to GND for single-supply operation - simplifies design in +3.3V/+5V systems. |
| 5 | GND | Ground reference for logic and analog sections - requires low-impedance connection to minimize noise coupling into sensitive analog paths. |
| 12 | N.C. | No internal connection - leave unconnected; no routing or thermal relief required. |
| 13 | V+ | Positive supply input; supports up to +11V - enables operation directly from unregulated battery stacks or DC-DC outputs. |
Key Features
| Feature | Design Value |
|---|---|
| Fault-protected NO inputs | Withstands ±12V transients with power off - eliminates need for external TVS diodes in field-serviceable equipment. |
| Rail-to-rail signal handling | Passes analog signals from V− to V+ without clipping - preserves full dynamic range in sensor front-ends and DAC outputs. |
| Output clamping during fault | COM pins clamp to V+ (positive fault) or V− (negative fault) - prevents downstream IC latch-up or ADC saturation. |
| Pin-compatible with MAX392 | Direct drop-in replacement for legacy non-fault-protected switches - reduces redesign effort in existing PCB layouts. |
| Low charge injection (25pC) | Minimizes voltage glitch on high-impedance nodes (e.g., sample-hold capacitors) - critical for precision data acquisition accuracy. |
Applications
| Automated Test Equipment (ATE) | Battery-Powered Data Loggers |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX392ESE+ | No fault protection; 35Ω RON max; same 16-pin SO package and pinout. | Suitable only in benign environments where overvoltage risk is mitigated externally. | Select when cost sensitivity outweighs fault resilience and board space permits adding TVS diodes. |
| ADG1412BRUZ | 4-channel SPST, ±15V supply capable, 1.8Ω RON, but no integrated fault protection - requires external clamps. | Better performance in high-voltage industrial automation, but higher BOM count and layout complexity. | Choose for ultra-low RON and wider supply range where fault protection can be implemented at system level. |
Compared with MAX392ESE+ and ADG1412BRUZ, the MAX4712EUE+ uniquely integrates ±12V fault protection without external components, offers rail-to-rail signal handling down to +2.7V, and maintains pin compatibility with legacy designs - making it optimal for ruggedized, space-constrained, and retrofit applications.

FAQ
What is the maximum fault voltage the MAX4712EUE+ can withstand on its NO pins?
The MAX4712EUE+ withstands ±12V on NO pins with power off, and ±7V with ±5V dual supplies. With +5V single supply, it handles +12V and –7V; with +3V supply, +12V and –9V. These limits are absolute - exceeding them risks permanent damage. The fault protection activates when NO voltage exceeds V+ or V− by ~150mV, clamping COM to the respective rail.
Is the MAX4712EUE+ pin-compatible with non-fault-protected analog switches?
Yes, the MAX4712EUE+ has identical pinout to the industry-standard MAX392 and other 16-pin quad SPST switches. However, only NO/NC pins are fault-protected - COM pins retain standard CMOS behavior and must stay within V− to V+. Direct replacement is viable if system-level fault exposure is limited to NO-side signals.
Can the MAX4712EUE+ operate from a single +3.3V supply?
Yes, the MAX4712EUE+ operates from +2.7V to +11V single supply. At +3.3V, RON is ≤75Ω (typical), tON ≤500ns, and logic thresholds are VIH = 2.0V / VIL = 0.6V - fully compatible with 3.3V microcontrollers. Fault protection remains active, supporting ±12V transients with power off.
Why does the MAX4712EUE+ specify different fault recovery times for dual vs. single supply?
Fault recovery time depends on COM output resistance and load capacitance. Under dual ±5V supply, recovery is 700ns; under +5V single supply, it extends to 500µs for negative faults due to lower clamp current drive capability from V− (GND). This reflects actual measured behavior - not a specification limit - and must be accounted for in timing-critical fault-clearance sequences.
Does the MAX4712EUE+ require external pull-up or pull-down resistors on its IN pins?
No. The MAX4712EUE+ features TTL/CMOS-compatible logic inputs with guaranteed VIH ≥2.4V and VIL ≤0.8V across its full supply range. Input leakage is ±1µA max, so direct connection to microcontroller GPIOs is safe. External resistors are unnecessary unless specific noise immunity or default-state biasing is required by system architecture.
