Product details
Overview
MAX4711ESE from Maxim Integrated is a fault-protected, quad SPST analog switch with four normally closed (NC) channels, 25Ω max on-resistance at +25°C, ±2.7V to ±5.5V dual-supply or +2.7V to +11V single-supply operation, and rail-to-rail signal handling - used in battery-operated test equipment for robust signal routing under overvoltage fault conditions.
For engineers reviewing the MAX4711ESE datasheet, MAX4711ESE pinout, MAX4711ESE application, or MAX4711ESE equivalent, this page delivers verified electrical specs, fault-protection behavior, thermal operating range (-40°C to +85°C), package mapping to 16-pin narrow SO, and real-world selection guidance against comparable analog switches.
Technical Context
The MAX4711ESE integrates parallel N- and P-channel FETs per channel to achieve low RON and flat on-resistance across signal range. Its dual-comparator fault-sensing circuit monitors NO_/NC_ pins continuously, triggering clamp FETs (P2/N2) when input exceeds V+ or V− by ~150mV - clamping COM_ to the appropriate supply without latch-up.
Fault response is asymmetric: turn-on delay is 200ns, but recovery time reaches 700ns after transient fault removal. The device remains fault-protected with power off (±12V tolerance), and digital inputs tolerate TTL/CMOS logic thresholds across supply ranges - enabling interoperability in mixed-voltage industrial control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance (RON) | 25Ω max at +25°C, dual ±4.5V - ensures minimal signal attenuation in precision data-acquisition paths |
| On-resistance match | 1Ω max between channels - critical for matched gain/phase in multi-channel instrumentation |
| Fault protection range | ±12V on NO_/NC_ with power off - enables safe hot-plug or sensor disconnect in avionics backup systems |
| Supply range | +2.7V to +11V single or ±2.7V to ±5.5V dual - supports wide-input battery systems (e.g., Li-ion, 2–3S) and legacy ±5V rails |
| Switching speed | tON < 125ns, tOFF < 80ns at ±4.5V - suitable for high-speed multiplexing in automated test equipment |
| Operating temperature | -40°C to +85°C - qualified for industrial and automotive under-hood environments |
| Logic compatibility | VIH = +2.4V / VIL = +0.8V at ±4.5V–±5.5V - direct interface with 3.3V/5V microcontrollers without level shifters |
Pinout & Package
MAX4711ESE is housed in a 16-pin narrow SO package (SOIC-16, 300 mil width), with exposed pad not present and moisture sensitivity level (MSL) rated per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 (Pins 1, 8, 9, 16) | Logic control inputs | Fault-protected to (V− + 12V); drive internal switch state; TTL/CMOS compatible |
| COM1–COM4 (Pins 2, 7, 10, 15) | Analog common terminals | Not fault-protected - must remain within V− to V+; output node during conduction |
| NC1–NC4 (Pins 3, 6, 11, 14) | Normally closed analog inputs | Fault-protected to ±12V (power off) or (V− +12V)/(V+ −12V) (power on); connected to COM when IN = 0 |
| V+ (Pin 13) | Positive supply | Accepts +2.7V to +11V (single) or +2.7V to +5.5V (dual); powers clamp and logic circuits |
| V− (Pin 4) | Negative supply | Accepts −2.7V to −5.5V (dual) or GND (single); reference for negative fault detection |
| GND (Pin 5) | Ground reference | System ground return; required for single-supply operation and ESD path |
| N.C. (Pin 12) | No connection | Internally unconnected - must be left floating or tied to GND for mechanical stability |
Key Features
| Feature | Design Value |
|---|---|
| Fault-protected NC inputs | NO_/NC_ pins withstand ±12V with power off - eliminates need for external TVS in field-deployed sensor interfaces |
| Rail-to-rail signal handling | Full V− to V+ analog swing passes through with <25Ω RON - preserves dynamic range in ±5V op-amp signal chains |
| Output clamping during fault | COM_ actively clamped to V+ or V− during overvoltage - protects downstream ADCs or FPGA I/O banks |
| Pin-compatible upgrade | Direct replacement for MAX391/MAX392/MAX393 - enables drop-in reliability enhancement in legacy designs |
| Low leakage performance | <±10nA COM_/NO_/NC_ off-leakage at +25°C - essential for high-impedance pH or thermocouple measurement front-ends |
Applications
| Battery-Operated Test Equipment | Avionics 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 |
|---|---|---|---|
| MAX391CSE | No fault protection; 35Ω RON max; same 16-pin narrow SO package and pinout | Lacks ±12V fault tolerance - requires external protection for field-connected sensors | Select when cost sensitivity outweighs fault resilience and system-level protection is already implemented |
| ADG1411BRUZ | 4-channel SPST, but normally open (NO); 1.8Ω RON max; 16-TSSOP only; no fault protection | Lower RON but incompatible pinout and logic polarity - requires PCB redesign | Choose for ultra-low on-resistance in lab-grade instrumentation where fault events are controlled |
Compared with MAX391CSE and ADG1411BRUZ, the MAX4711ESE uniquely combines pin compatibility with integrated ±12V fault protection and rail-to-rail operation - making it the only option that upgrades reliability without layout changes or external components.

FAQ
What is the maximum fault voltage the MAX4711ESE can withstand with power removed?
The MAX4711ESE guarantees ±12V fault protection on NO_/NC_ pins even with all supplies disconnected. This is confirmed in the Absolute Maximum Ratings table and applies regardless of V+ or V− voltage - enabling safe handling during maintenance or field servicing of MAX4711ESE-equipped equipment.
Does the MAX4711ESE support single-supply operation below +3V?
Yes, the MAX4711ESE operates from +2.7V to +11V single supply (V− = GND). At +2.7V, RON rises to 100Ω max and logic thresholds shift to VIH = +2.0V/VIL = +0.6V - verified in the +3V Single Supply Electrical Characteristics table for the MAX4711ESE's extended temperature grade.
Is the COM_ pin fault-protected on the MAX4711ESE?
No, the COM_ pins on the MAX4711ESE are not fault-protected. As stated in Note 1 of the datasheet, signals applied to COM_ must stay within V− to V+, otherwise ESD diodes conduct - risking damage if forward current exceeds ±40mA. External clamping is required for COM_-side overvoltage.
How does the MAX4711ESE differ from the MAX4712ESE in functionality?
The MAX4711ESE contains four normally closed (NC) switches, while the MAX4712ESE has four normally open (NO) switches. Both share identical fault protection, timing, and electrical specs - the difference lies solely in default state: MAX4711ESE connects COM to NC when logic input is low, whereas MAX4712ESE connects only when input is high.
Can the MAX4711ESE replace MAX391 in an existing PCB layout?
Yes - the MAX4711ESE is pin-compatible with MAX391CSE/MAX391ESE in the 16-pin narrow SO package and shares identical IN/COM/NC pin assignments. However, due to its fault-protection architecture, verify that NO_/NC_ nodes are not driven beyond ±12V relative to GND in the original design before substitution.
