Product details
Overview
MAX4711CUE+ from Maxim Integrated is a fault-protected, quad SPST analog switch with four normally closed (NC) channels, rail-to-rail signal handling, 25Ω max on-resistance at +25°C, ±12V fault protection with power off, and operation from +2.7V to +11V single supply or ±2.7V to ±5.5V dual supplies. It enables robust signal routing in battery-operated test equipment where input overvoltage events must not damage downstream circuitry.
For engineers reviewing the MAX4711CUE+ datasheet, MAX4711CUE+ pinout, MAX4711CUE+ application, or MAX4711CUE+ equivalent, this page delivers verified specifications, fault-protection behavior under transient overvoltage, real-world switching timing across supply voltages, package-level thermal derating, and validated alternatives for redundant system design.
Technical Context
The MAX4711CUE+ uses parallel N- and P-channel FETs per channel to achieve low RON and flat on-resistance vs. signal voltage. Its dual comparator-based fault detection senses >±150mV excursion beyond V+ or V−, disabling the main switch path and activating clamp FETs to limit COM output to the appropriate supply rail.
Fault response is asymmetric: turn-on delay is 200ns, but recovery after fault removal takes 700ns (dual supply) or up to 2.2µs (+3V supply), dependent on COM load impedance. Digital inputs are TTL/CMOS-compatible with VIH = +2.4V and VIL = +0.8V under +4.5V–+11V or ±4.5V–±5.5V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 25Ω max at +25°C, +4.5V/+5.5V dual supply - ensures minimal signal attenuation in precision analog paths |
| On-resistance match | 1Ω max between channels - critical for matched gain/phase in multi-channel instrumentation |
| Fault protection range | ±12V on NO_/NC_ pins with power off - protects connected circuitry during system power-down |
| Switching speed | tON < 125ns, tOFF < 80ns (dual ±4.5V) - supports high-speed multiplexing in data acquisition |
| Supply range | +2.7V to +11V single or ±2.7V to ±5.5V dual - enables use in 3V, 5V, and ±5V industrial systems |
| Logic compatibility | TTL/CMOS thresholds (VIH = +2.4V, VIL = +0.8V) - simplifies interface with microcontrollers and FPGAs |
| Off-isolation | -59dB at 1MHz - suppresses crosstalk between inactive channels in dense signal routing |
Pinout & Package
MAX4711CUE+ is housed in a 16-pin TSSOP package (3.1mm × 5.1mm, 0.65mm pitch), rated for 0°C to +70°C operation. Thermal derating is 5.70mW/°C above +70°C (457mW max at +70°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Fault-protected to (V− + 12V); drive internal switches; compatible with TTL/CMOS logic levels |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Not fault-protected; must remain within V− to V+; connect to load or signal path |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog inputs | Fault-protected to ±12V (power off) or −12V+V+ to +12V (power on); default closed path |
| V+ (Pin 13) | Positive supply input | Accepts +2.7V to +11V; powers internal logic and clamp FETs |
| V− (Pin 4) | Negative supply input | Accepts −2.7V to −5.5V; connect to GND for single-supply operation |
| GND (Pin 5) | Ground reference | Logic and analog ground return; ties to system GND plane |
| N.C. (Pin 12) | No connection | Internally unconnected; leave floating or tie to GND for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Fault-protected NC inputs | NO_/NC_ pins withstand ±12V transients with power off - eliminates need for external TVS diodes in field-deployed test gear |
| Rail-to-rail analog switching | Signal range extends from V− to V+ - preserves full dynamic range of sensors and DAC outputs |
| Clamped COM output during fault | COM is actively limited to V+ or V− polarity during overvoltage - prevents latch-up or damage to downstream ADCs |
| Pin-compatible upgrade | Direct replacement for MAX391/MAX392/MAX393 - enables retrofitting fault protection without PCB redesign |
| Low leakage performance | <±10nA COM/NO_/NC_ off-leakage at +25°C - maintains accuracy in high-impedance sensor front-ends |
Applications
| Battery-Operated Test Equipment | Redundant Signal Routing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4712CUE+ | Four normally open (NO) configuration instead of NC; identical fault protection, RON, and timing specs | Suitable when default-open signal path is required (e.g., safety-critical disconnect on power-up) | Select MAX4712CUE+ only if system logic requires active-low enable behavior or failsafe open state |
| ADG1412BRUZ | Non-fault-protected, 1.5Ω typical RON, 16-TSSOP, +3V to +40V supply - no ±12V fault tolerance or clamp action | Used in high-precision DC-coupled instrumentation where overvoltage risk is controlled externally | Choose ADG1412BRUZ only when fault protection is handled at board level and ultra-low RON outweighs protection needs |
Compared with MAX4712CUE+, the MAX4711CUE+ provides fail-safe closed-path behavior ideal for monitoring circuits that must remain connected until commanded otherwise; versus ADG1412BRUZ, it trades 1.5Ω lower RON for integrated ±12V fault resilience-critical in uncontrolled field environments.

FAQ
What is the maximum fault voltage the MAX4711CUE+ can withstand with power removed?
The MAX4711CUE+ guarantees ±12V fault protection on NO_/NC_ pins even when powered off. This is specified in the Absolute Maximum Ratings table and confirmed in the Fault-Protection Voltage and Power Off section of the datasheet. The device achieves this via internal high-impedance isolation, making it suitable for hot-swap or maintenance scenarios where inputs may be exposed before system power-up.
Does the MAX4711CUE+ support single-supply operation, and what is the minimum voltage?
Yes, the MAX4711CUE+ operates from a single +2.7V to +11V supply, with V− tied to GND. At +2.7V, logic thresholds shift to VIH = +2.0V and VIL = +0.6V, and RON rises to 100Ω max. This enables use in 3V battery-powered systems, though designers must verify timing (tON up to 600ns) and leakage (<±10nA) meet application requirements.
How does the fault protection mechanism affect the COM pin during overvoltage?
During a fault, the MAX4711CUE+ clamps the COM output to the same-polarity supply rail (V+ for positive faults, V− for negative faults) using internal clamp FETs. The COM pin itself is not fault-protected - exceeding V+ or V− by more than a diode drop forward-biases ESD diodes, risking damage. Therefore, COM must always remain within the supply rails, unlike NO_/NC_.
Is the MAX4711CUE+ pin-compatible with legacy analog switches?
Yes, the MAX4711CUE+ has identical pinout to the industry-standard MAX391/MAX392/MAX393 family. However, only NO_/NC_ pins are fault-protected - COM pins retain standard CMOS switch behavior. When replacing non-fault-protected parts, ensure system-level overvoltage risks are assessed, as the fault response (clamping, high-Z input) differs fundamentally from basic switches.
What is the on-resistance match specification for the MAX4711CUE+, and why does it matter?
The MAX4711CUE+ guarantees ≤1Ω on-resistance match (∆RON) between its four NC channels at +25°C. This tight matching ensures uniform signal gain, phase, and settling time across all switched paths - essential in multi-channel data acquisition, precision calibration systems, and differential signal routing where channel-to-channel consistency directly impacts measurement accuracy.
