Product details
Overview
MAX4711CSE from Maxim Integrated is a fault-protected, quad SPST analog switch with normally closed (NC) configuration, designed for signal routing in low-voltage systems. It delivers 25Ω max on-resistance at +25°C, <125ns turn-on time, and ±12V fault protection with power off-enabling robust operation in battery-powered test equipment and avionics where input overvoltage transients are common.
For engineers reviewing the MAX4711CSE datasheet, MAX4711CSE pinout, MAX4711CSE application, or MAX4711CSE equivalent, key selection criteria include its rail-to-rail signal handling, guaranteed on-resistance match ≤1Ω between channels, fault-clamp behavior during overvoltage events, and pin compatibility with industry-standard MAX391/MAX392/MAX393 switches.
Technical Context
The MAX4711CSE uses dual parallel FETs (N- and P-channel) per switch to achieve low RON and flat on-resistance across the signal range. Its internal fault-sensing comparators detect when NO_/NC_ inputs exceed V+ or V− by ~150mV, triggering automatic shutdown and output clamping to the appropriate supply rail.
Fault response is asymmetric: during positive faults, P2 clamp FET sources current from V+ to COM_; during negative faults, N2 sinks current to V−. COM_ pins lack fault protection and rely on ESD diodes-exceeding V+/V− risks damage unless current-limited.

Use Value: 25Ω RON and ≤1Ω matching enable sub-0.1% gain error across ranges-meeting Class II handheld meter accuracy requirements. |
| Redundant Backup Systems | Industrial Process Control I/O |
Use Scenario: Dual-path analog signal selection in safety-critical PLC modules, where primary and backup sensor feeds feed separate AFEs. IC Role / Device Role / Timing Role: Normally closed configuration ensures default signal path remains active during controller boot or communication failure. Use Value: "Fail-safe" NC behavior maintains process visibility during firmware updates-avoiding production line downtime due to transient controller outages. | Use Scenario: Channel isolation in modular analog input cards for programmable logic controllers handling 4–20mA and ±10V field signals. IC Role / Device Role / Timing Role: Switches isolate individual channels before ADC sampling; fault protection absorbs induced surges from long cable runs. Use Value: ±7V fault tolerance with ±5V supplies eliminates need for discrete surge suppression per channel-reducing BOM cost by 35% vs. non-fault-protected alternatives. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar 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 transient immunity-requires external protection for industrial or avionics use | Select only for cost-sensitive, benign-environment applications where overvoltage risk is negligible |
| ADG1411BRUZ | Quad SPST, NC, but no fault protection; 1.8Ω RON typ; 16-TSSOP, not pin-compatible | Superior RON and bandwidth, but requires PCB layout change and adds external TVS for field deployment | Choose when ultra-low on-resistance is critical and board revision is feasible |

FAQ
What is the maximum fault voltage the MAX4711CSE can withstand with power removed?
The MAX4711CSE sustains ±12V fault voltage on its NO_/NC_ pins even with all supplies disconnected. This is specified in the Absolute Maximum Ratings table and verified across the commercial temperature range (0°C to +70°C). The device enters high-impedance mode during this condition, protecting downstream circuitry without external components. MAX4711CSE does not provide fault protection on COM_ pins-those must remain within V− to V+ rails at all times.
Does the MAX4711CSE support single-supply operation, and what is the minimum supply voltage?
Yes, the MAX4711CSE operates from a single +2.7V to +11V supply with V− tied to GND. At +2.7V, it maintains functional logic thresholds (VIH = 2.0V, VIL = 0.6V) and delivers 100Ω max on-resistance. The 2.7V minimum enables direct integration with 3V microcontrollers and low-power sensors. MAX4711CSE retains full fault-protection capability-including ±12V tolerance with power off-even at the 2.7V operating point.
How does the fault-clamp behavior of the MAX4711CSE affect connected loads?
During a fault, the MAX4711CSE clamps COM_ to V+ (for positive overvoltage) or V− (for negative overvoltage) via internal P2 or N2 FETs, which can source/sink up to ±15mA. Loads must be designed to accept this clamped voltage without drawing excessive current-absolute maximum COM_ current remains ±40mA. MAX4711CSE's clamp resistance is 200Ω typ (dual supply) or 500Ω typ (+5V single), limiting fault current naturally. Exceeding 40mA risks permanent damage.
Is the MAX4711CSE pin-compatible with the MAX391 series, and are there any layout considerations?
Yes, the MAX4711CSE shares identical pinout and footprint with MAX391CSE, MAX392CSE, and MAX393CSE in the 16-pin narrow SO package. However, only NO_/NC_ pins are fault-protected-COM_ pins retain standard CMOS switch behavior and lack overvoltage tolerance. When replacing MAX391CSE, verify that COM_ nodes are never driven beyond V+/V−, and confirm that system-level fault energy falls within the ±40mA absolute maximum rating. MAX4711CSE introduces no PCB changes but demands attention to COM_ voltage constraints.
What is the on-resistance flatness specification for the MAX4711CSE, and why does it matter in precision applications?
The MAX4711CSE guarantees on-resistance flatness (RFLAT) of ≤5Ω over the full signal range (V− to V+) at +25°C with ±4.5V supplies. Flatness quantifies variation in RON versus signal voltage-critical in precision gain-setting, filter tuning, and sensor interface circuits where nonlinear resistance causes harmonic distortion or gain error. With ≤5Ω variation across a 10V span, MAX4711CSE achieves <0.05% flatness error-supporting 12-bit+ accuracy in buffered analog paths without calibration.
