Product details
Overview
DG411FEUE+ from Maxim Integrated is a quad, normally closed (NC), fault-protected SPST analog switch with rail-to-rail signal handling, 35Ω max on-resistance at ±15V, ±36V fault protection with power on, and 16-pin TSSOP package. It operates across ±4.5V to ±20V dual supplies or +9V to +36V single supply, and is used in industrial signal routing where overvoltage resilience and channel isolation are critical.
For engineers reviewing the DG411FEUE+ datasheet, DG411FEUE+ pinout, DG411FEUE+ application, or DG411FEUE+ equivalent, key selection criteria include fault-protection voltage limits (±40V power-off), NC-only topology, matched on-resistance (≤1.5Ω), sub-20ns fault response time, and compatibility with TTL/CMOS logic under ±15V or +12V supply conditions.
Technical Context
The DG411FEUE+ implements dual-FET (N+P channel) parallel switching per channel to achieve low RON and true rail-to-rail conduction. Its internal comparators monitor COM/NO/NC terminals continuously against V+ and V−, triggering immediate high-impedance isolation upon overvoltage detection.
Fault response is polarity-agnostic: positive faults (>V+ +50mV) and negative faults ( Package: 16-pin TSSOP (JEDEC MO-153, outline 21-0066), RoHS-compliant, 4.4mm × 5.0mm footprint, 0.65mm pitch. Use Scenario: Multiplexing sensor outputs (e.g., thermocouples, strain gauges) into a shared ADC in harsh factory environments with ESD and cable-induced transients. IC Role / Device Role / Timing Role: Fault-protected analog switch providing channel selection and overvoltage isolation prior to signal conditioning. Use Value: Prevents damage to precision front-end amplifiers during ±36V line surges while maintaining <35Ω path resistance for minimal gain error. Use Scenario: Selecting between primary and backup flight control sensors in airborne systems where power interruption and lightning-induced transients are mission-critical concerns. IC Role / Device Role / Timing Role: NC-configured switch ensuring default signal path continuity during power loss or control failure. Use Value: Maintains signal integrity during V+ dropout via automatic shutdown and ±40V power-off fault tolerance - meets DO-160 Section 22 surge immunity requirements. Use Scenario: Routing DUT signals through calibration paths and protection networks in semiconductor test handlers exposed to repeated hot-plug events and probe contact bounce. IC Role / Device Role / Timing Role: High-speed, low-leakage analog switch enabling repeatable measurement paths with sub-20ns fault cutoff. Use Value: 0.25nA max off-leakage preserves femtoamp-level current measurements; 20ns fault trip prevents transient-induced measurement corruption. Use Scenario: Isolating 4–20mA loop transmitters from PLC analog inputs in chemical plant control cabinets subject to ground potential differences and lightning coupling. IC Role / Device Role / Timing Role: Fault-tolerant interface switch decoupling field wiring from sensitive controller circuitry. Use Value: ±36V fault protection withstands common-mode surges on long cable runs; rail-to-rail operation accommodates full 0–24V loop compliance range. The following parts are listed as comparable options for similar analog switch applications. Compared with MAX4711EUE+ and ADG411BRUZ, the DG411FEUE+ uniquely delivers integrated ±40V power-off fault tolerance, rail-to-rail operation, and pin compatibility with legacy DG411 - eliminating external protection components and enabling direct upgrade paths in existing industrial and avionics platforms. DG411FEUE+ is available at Aetrix Electronics and suitable for industrial signal routing, avionics redundancy switching, and automated test equipment requiring stable component supply, long-term lifecycle support, and guaranteed fault-protection performance. Supply support for DG411FEUE+ includes scheduled delivery planning, volume procurement assistance, BOM continuity management, traceable sourcing, and lifecycle availability coordination for OEM customers, industrial embedded developers, connected-device designers, and electronics production programs. Maxim Integrated (now part of Analog Devices) designs high-performance analog, mixed-signal, and power management ICs for demanding industrial, automotive, and communications applications. The DG411FEUE+ belongs to Maxim's fault-protected analog switch family, engineered specifically for systems where signal integrity must be preserved under electrical stress - including factory automation, aerospace, and test instrumentation. The DG411FEUE+ sustains ±36V fault voltage on COM_, NC_, or NO_ terminals with power applied - verified across ±15V dual supplies and +12V single-supply operation. This rating applies regardless of switch state (on/off) and ensures protection against common industrial transients without external components. No - the DG411FEUE+ does not require power-supply sequencing. V+ and V− may be powered in any order, and the device remains functional and fault-protected throughout startup. This eliminates risk of undefined logic states or latch-up in systems with asymmetric supply ramp rates. When V+ is disconnected, all four switches in the DG411FEUE+ turn off immediately - even if V− is still powered and IN inputs are asserted. This fail-safe behavior prevents unintended conduction and maintains isolation, aligning with safety-critical system requirements. Yes - the DG411FEUE+ uses identical pinout and footprint as the industry-standard DG411. All COM_, NC_, IN_, V+, V−, GND, and N.C. assignments match exactly, enabling drop-in replacement without PCB modification or layout changes. The DG411FEUE+ exhibits ≤3Ω on-resistance flatness (RFLAT(ON)) across ±5V and 0V signal conditions at +25°C. This tight variation ensures consistent gain and minimal harmonic distortion in audio, sensor, and instrumentation signal paths.Key Specifications

Selection Advice
MAX4711EUE+
Same NC topology, but rated only for ±5V/5V supplies; lacks ±36V fault protection and rail-to-rail capability
Suitable for low-voltage battery-powered systems only; cannot replace DG411FEUE+ in industrial ±15V designs
Select MAX4711EUE+ only when supply is strictly ≤5V and fault exposure is negligible
ADG411BRUZ
Quad NC SPST, 35Ω RON, but no integrated fault protection - requires external TVS diodes and clamping circuits
Demands additional board space and BOM cost for discrete protection; no guaranteed ±40V power-off isolation
Choose ADG411BRUZ only when design allows external protection and cost sensitivity outweighs integration benefit
