Product details
Overview
DG411CUE+T from Maxim Integrated is a quad, normally closed (NC), single-pole/single-throw (SPST) analog switch IC designed for precision signal routing in bipolar or single-supply systems. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, and operates from ±4.5V to ±20V or +10V to +30V supplies - enabling use in battery-operated test equipment and military radios.
For engineers reviewing the DG411CUE+T datasheet, DG411CUE+T pinout, DG411CUE+T application, or DG411CUE+T equivalent, key selection criteria include guaranteed RON matching (≤3Ω), rail-to-rail analog signal handling (±15.5V), TTL/CMOS logic compatibility, and ESD tolerance of ≥2000V per Method 3015.7.
Technical Context
The DG411CUE+T implements four independent NC SPST switches fabricated in a 44V silicon-gate process. Each channel guarantees matched on-resistance (ΔRDS(ON) ≤3Ω) and flat on-resistance over the full analog range (ΔRFLAT(ON) ≤4Ω), with bidirectional conduction capability and low charge injection (≤10pC).
It supports dual-supply operation (±4.5V to ±20V) or single-supply operation (+10V to +30V), with VL pin configurable for TTL (5V) or CMOS (V+) logic level compatibility. Switching times are specified at tON ≤150ns and tOFF ≤100ns under VD = ±10V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-Resistance (RDS(ON)) | 35Ω max at ±15V supplies - ensures minimal signal attenuation and voltage drop in precision analog paths |
| RDS(ON) Match | 3Ω max between channels - enables consistent gain/attenuation across multiple switched signal paths |
| Charge Injection | 10pC max - reduces sampling error and pedestal distortion in sample-and-hold circuits |
| Off-Leakage Current | <5nA at +85°C - maintains high-impedance isolation critical for low-current sensor interfaces |
| Analog Signal Range | ±15.5V with ±16.5V supplies - supports rail-to-rail signal handling without clipping |
| ESD Tolerance | 2000V min per Method 3015.7 - provides robust handling during board assembly and field operation |
| Supply Range | ±4.5V to ±20V or +10V to +30V - accommodates industrial, military, and battery-powered system architectures |
Pinout & Package

| D1–D4 | Analog Drain Terminal | High-impedance side of switch - connects to load or downstream circuitry |
| S1–S4 | Analog Source Terminal | Low-impedance side tied to common reference - bidirectional conduction supported |
| V+, V− | Analog Supply Rails | Establish analog signal range; V+ connected to substrate; absolute max differential = 44V |
| GND | Ground Reference | Signal return for logic and analog sections - separate from power ground in mixed-signal layouts |
| VL | Logic Supply Voltage | Set to 5V for TTL compatibility or V+ for CMOS thresholds - defines input logic threshold levels |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG411BRUZ | 44V supply rating; 35Ω RON; 15pC charge injection; SOIC-16 package | Higher charge injection limits use in sub-12-bit sample-and-hold; no TSSOP option | Select when SOIC-16 footprint required and 15pC injection is acceptable |
| TS5A23157DCUR | Single-supply only (1.65V–5.5V); 0.9Ω RON; 3pC charge injection; 10-pin VSSOP | Not suitable for ±15V signal routing; optimized for low-voltage digital I/O switching | Select only for 3.3V/5V logic-level signal routing - not a functional replacement for DG411CUE+T |
Compared with ADG411BRUZ and TS5A23157DCUR, the DG411CUE+T uniquely supports bipolar ±20V operation, guarantees ≤3Ω RON matching, and delivers NC fail-safe behavior - making it irreplaceable in high-voltage, precision, or safety-critical analog routing.

FAQ
What is the operating temperature range for DG411CUE+T?
The DG411CUE+T is rated for 0°C to +70°C ambient operation. This commercial-grade temperature range is defined by the 'C' suffix in the part number and validated per Maxim's characterization data. The device uses a silicon-gate process that ensures stable RDS(ON) and leakage performance across this range, with off-leakage guaranteed at <5nA at +85°C - providing margin beyond its rated max.
Is DG411CUE+T pin-compatible with legacy DG411 variants?
Yes, DG411CUE+T is pin-compatible with other 16-pin DG411 variants including DG411CJ (DIP), DG411CY (SO), and DG411EUE (industrial TSSOP). All share identical pinout, logic behavior (NC), and electrical specifications per the same datasheet. The 'CUE' designation indicates the 16-pin TSSOP package with commercial temperature grade - no PCB redesign is needed when upgrading from DIP or SO packages.
Does DG411CUE+T support single-supply operation?
Yes, DG411CUE+T supports single-supply operation from +10V to +30V. In this configuration, connect V− to ground (0V), apply the positive supply to V+, and set VL to 5V for TTL compatibility. The analog signal range becomes 0V to V+ − 1V (e.g., 0V to +29V at +30V supply), preserving rail-to-rail functionality while simplifying power design in portable or DC-powered systems.
What is the maximum analog signal voltage DG411CUE+T can handle?
DG411CUE+T supports an analog signal range of ±15.5V when operated with ±16.5V supplies - verified per the Electrical Characteristics table. This is limited by the absolute maximum ratings: signals on S/D pins must remain within (V− −2V) to (V+ +2V). Exceeding these clamps internal diodes and risks permanent damage; external protection diodes are recommended for overvoltage-prone applications.
How does the normally closed (NC) configuration affect system reliability?
The DG411CUE+T's NC topology ensures signal continuity between S and D terminals when IN = 0V (logic low) or during power loss, reset, or un-driven control states. This fail-safe behavior prevents open-circuit faults in critical paths such as sensor monitoring or safety interlocks - a key reliability advantage over NO switches like DG412CUE+T in systems where uninterrupted signal flow is mandatory.
