Product details
Overview
DG411FEUE+T from Maxim Integrated is a quad SPST analog switch with normally closed (NC) configuration, fault-protected inputs, rail-to-rail signal handling, 35Ω max on-resistance at ±15V, ±36V fault protection with power on, and 16-pin TSSOP package. It serves in high-reliability signal routing for test equipment and industrial control systems where overvoltage transients are present.
For engineers reviewing the DG411FEUE+T datasheet, DG411FEUE+T pinout, DG411FEUE+T application, or DG411FEUE+T equivalent, key selection criteria include fault-protection voltage range, on-resistance matching across channels, rail-to-rail analog signal support, and compatibility with ±4.5V to ±20V dual or +9V to +36V single supplies.
Technical Context
The DG411FEUE+T implements dual-FET (N+P channel) parallel switching per channel to achieve low RON and symmetric bidirectional conduction. Its internal fault-detection comparators monitor COM_, NO_, and NC_ terminals against V+ and V−, triggering immediate high-impedance isolation when signals exceed V+ + 50mV or fall below V− − 50mV.
It operates with TTL/CMOS-compatible logic thresholds (VIH = 2.4V, VIL = 0.8V) across supply ranges and maintains all switches OFF during power-off or V+ loss - critical for system-level safety in avionics and redundant backup systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four switches conduct when logic input is low. |
| On-Resistance (RON) | 35Ω max at ±15V, +25°C - ensures minimal signal attenuation and thermal drift in precision analog paths. |
| Fault Protection | ±36V with power on, ±40V with power off - protects downstream circuitry without external clamping diodes. |
| Supply Range | ±4.5V to ±20V dual or +9V to +36V single - supports legacy ±15V industrial rails and modern high-voltage single-supply designs. |
| Logic Compatibility | TTL/CMOS thresholds (VIH = 2.4V, VIL = 0.8V) at ±15V or +12V - eliminates level-shifting in mixed-signal controller interfaces. |
| Turn-On/Off Time | 70ns/55ns typ (±15V), 120ns/70ns typ (+12V) - enables fast multiplexing in data acquisition and communication switching. |
| Leakage Current | ±0.25nA max COM_/NO_/NC_ off-leakage at ±10V - preserves signal integrity in high-impedance sensor front-ends. |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MO-153, outline 21-0066), RoHS-compliant, 4.4mm × 5.0mm footprint, 0.65mm pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Digital control inputs - active-low logic drives NC closure; CMOS/TTL compatible. |
| 2, 7, 10, 15 | COM1–COM4 | Analog common terminals - bidirectional signal path; fault-protected up to ±40V. |
| 3, 6, 11, 14 | NC1–NC4 | Normally closed analog terminals - conduct to COM when IN = low; fault-protected. |
| 4 | V− | Negative supply rail - connect to GND for single-supply operation; bypass with 0.1µF capacitor. |
| 5 | GND | Digital ground reference - separate from analog signal ground; no galvanic connection to COM/NC paths. |
| 12 | N.C. | No internal connection - leave unconnected; no routing or grounding required. |
| 13 | V+ | Positive supply rail - supports up to +36V; bypass with 0.1µF capacitor to GND. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail signal handling | Supports analog signals from V− to V+ without clipping - enables full dynamic range utilization in ±15V or +12V systems. |
| 20ns typical fault response time | Isolates faulted terminal within 20ns - prevents latch-up or damage in transient-heavy environments like motor drive feedback loops. |
| No power-supply sequencing required | V+ and V− may be powered in any order - simplifies power management in multi-rail systems and avoids startup glitches. |
| All switches OFF with power off | Guaranteed high-impedance state when V+ = 0 - prevents backfeeding or unintended signal coupling during brownout or shutdown. |
| ±4.5V to ±20V dual / +9V to +36V single supply | Single BOM supports both legacy bipolar and modern high-voltage unipolar architectures - reduces inventory complexity. |
Applications
| Test Equipment Signal Routing | Industrial Process Control I/O |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4711EUE+ | Same pinout, identical NC function, but rated only for ±5V/5V supplies - lacks ±36V fault protection and rail-to-rail operation. | Suitable for low-voltage portable instrumentation; not viable in ±15V industrial or avionics contexts. | Select MAX4711EUE+ only if supply is strictly ≤±5V and fault exposure is negligible. |
| ADG1411YRUZ | Quad NC SPST with 1.8Ω RON, but no integrated fault protection - requires external ±40V clamps and failsafe logic. | Better for ultra-low-distortion audio routing; unsuitable for unattended fault-prone environments without added protection. | Choose ADG1411YRUZ when lowest on-resistance is critical and board space allows discrete protection components. |
Compared with MAX4711EUE+, DG411FEUE+ delivers robust fault resilience at higher voltages; versus ADG1411YRUZ, it trades 33Ω higher RON for fully integrated ±40V power-off protection and zero-layout overhead.

FAQ
What is the fault-protection voltage rating of DG411FEUE+T with power applied?
DG411FEUE+T provides ±36V fault protection on COM_, NC_, and NO_ terminals when power is applied - verified under ±15V dual-supply conditions. This rating applies regardless of switch state (open or closed) and ensures no destructive current flows beyond ±10µA during overvoltage events within this range.
Does DG411FEUE+T support single-supply operation, and what is the minimum voltage?
Yes, DG411FEUE+T supports single-supply operation with V− tied to GND and V+ ranging from +9V to +36V. At +9V, RON remains ≤45Ω and logic thresholds stay functional (VIH = 2.4V, VIL = 0.8V), making it viable for battery-backed industrial sensors and portable test instruments.
How does DG411FEUE+T behave when V+ is disconnected while V− remains active?
DG411FEUE+T turns all switches OFF immediately when V+ is removed - even if V− remains powered. This behavior is guaranteed by internal circuitry and ensures no unintended conduction paths exist, which is essential for safety-critical isolation in redundant systems.
What is the maximum continuous current rating per terminal of DG411FEUE+T?
DG411FEUE+T supports ±30mA continuous current on any terminal (COM_, NC_, or NO_), validated across its full operating temperature range (−40°C to +85°C). Exceeding this limit risks thermal overstress and accelerated parametric shift, especially at elevated ambient temperatures.
Is DG411FEUE+T pin-compatible with the legacy non-fault-protected DG411?
Yes, DG411FEUE+T uses identical pinout and footprint as the industry-standard DG411 - including matching IN_, COM_, NC_, V+, V−, GND, and N.C. assignments. This enables drop-in replacement without PCB modification, preserving layout integrity while upgrading fault resilience.
