Product details
Overview
DG211EUE+ from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage signal routing in industrial and test equipment. It operates across ±4.5V to ±18V dual supplies, delivers 175Ω max RDS(ON) at ±15V, exhibits 1000ns max turn-on time, and supports -40°C to +85°C operation in 16-pin TSSOP. It replaces legacy DG211 variants requiring VL supply.
For engineers reviewing the DG211EUE+ datasheet, DG211EUE+ pinout, DG211EUE+ application, or DG211EUE+ equivalent, key selection criteria include guaranteed break-before-make switching, no VL supply requirement, ±18V continuous operation, low OFF-leakage (±5nA), and compatibility with CMOS/TTL logic levels.
Technical Context
The DG211EUE+ implements monolithic CMOS SPST switches with integrated level-shifting logic, enabling direct interface to standard digital control signals without external biasing. Its architecture guarantees nonlatching behavior when power supplies are disconnected while analog inputs remain active.
Each of the four independent switches features symmetrical analog signal handling from -15V to +15V, 5pF typical OFF-capacitance per terminal, and 70dB minimum OFF-isolation at 100kHz - critical for precision multiplexing and signal integrity in mixed-signal systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail signal switching across industrial sensor and actuator interfaces |
| RDS(ON) Max | 175Ω at ±15V - ensures minimal insertion loss and voltage drop in precision analog paths |
| Turn-On Time Max | 1000ns - enables reliable timing in moderate-speed test instrumentation and data acquisition |
| OFF-Leakage Current | ±5nA at ±14V - preserves accuracy in high-impedance measurement circuits and sample-hold stages |
| Supply Range | ±4.5V to ±18V - allows flexible integration into legacy ±12V, ±15V, and modern ±5V systems |
| Logic Compatibility | CMOS/TTL - eliminates need for level translators when driven by microcontrollers or FPGAs |
| Operating Temp | -40°C to +85°C - qualified for extended industrial and avionics environments without derating |
Pinout & Package
Package: 16-pin TSSOP (4.4mm body width), RoHS-compliant, surface-mountable with 0.65mm pitch.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Active-low logic inputs controlling respective SPST switches; TTL/CMOS compatible |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - analog output side of each switch; bidirectional signal path |
| 3, 6, 11, 14 | S1–S4 | Source terminals - analog input side; normally connected to load or signal source |
| 4 | V− | Negative supply rail; must be connected to system −VEE; substrate reference |
| 5 | GND | Digital ground reference; separate from analog return but tied at system star point |
| 12 | N.C. | No internal connection - must be left floating or grounded per layout best practice |
| 13 | V+ | Positive supply rail; connected to substrate; requires stable ±15V or ±12V source |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail, simplifying PCB design and reducing BOM count vs. legacy DG211 |
| Guaranteed break-before-make | Prevents momentary short-circuit during channel switching - essential for fault-tolerant multiplexers |
| Nonlatching under signal-present power-off | Ensures safe operation when analog inputs remain live during power cycling or brownout |
| Low ON-resistance flatness | ≤175Ω over full ±15V analog range - maintains consistent gain and linearity across signal swing |
| High OFF-isolation | 70dB at 100kHz - suppresses crosstalk between adjacent channels in dense 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 |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (up to +36V); no negative rail support; 45Ω RDS(ON) at +15V | Not suitable for bipolar ±15V signal routing; limited to unipolar industrial sensors | Select only if system uses single positive supply and requires lower ON-resistance |
| ADG1412YRUZ | ±15V rated; 1.8Ω RDS(ON); 16-pin TSSOP; requires VL bias for logic interface | Superior ON-resistance but adds VL supply complexity; higher cost and power | Choose when ultra-low distortion is critical and VL supply infrastructure exists |
Compared with MAX4617ESE+ and ADG1412YRUZ, the DG211EUE+ uniquely balances bipolar ±18V operation, no-VL simplicity, and industrial temperature range - making it optimal for legacy-compatible, cost-sensitive, high-reliability analog routing where moderate speed suffices.

FAQ
What is the maximum continuous supply voltage range supported by DG211EUE+?
The DG211EUE+ supports continuous dual-supply operation from ±4.5V to ±18V. Absolute maximum ratings allow V+ to V− up to 44V, but sustained operation beyond ±18V is not guaranteed. This range enables compatibility with standard ±12V and ±15V industrial power rails without derating.
Does DG211EUE+ require a VL logic supply voltage?
No, DG211EUE+ does not require a VL supply. Unlike earlier DG211 versions from the original manufacturer, Maxim's DG211EUE+ integrates internal level-shifting circuitry, allowing direct CMOS/TTL logic interface using only V+, V−, and GND - reducing system complexity and component count.
What is the guaranteed RDS(ON) for DG211EUE+ at ±15V supplies?
The DG211EUE+ guarantees a maximum RDS(ON) of 175Ω at ±15V supplies, measured with VD = ±10V, VIN = 0.8V, and IS = 1mA. This value ensures predictable insertion loss and minimal signal attenuation in precision analog signal paths.
How does DG211EUE+ behave when power supplies are removed while analog signals remain present?
The DG211EUE+ is guaranteed nonlatching under this condition. Internal protection structures prevent parasitic SCR activation, ensuring the device remains in its last logic state without destructive current flow - a critical safety feature for systems with hot-swap or brownout scenarios.
Is DG211EUE+ pin-compatible with other DG211 package variants?
Yes, DG211EUE+ shares identical pinout and function mapping with all other 16-pin DG211 variants (e.g., DG211CSE, DG211DJ, DG211EGE). The TSSOP package (EUE) maintains mechanical and electrical equivalence across logic inputs, analog terminals, and supply pins - enabling drop-in replacement within same footprint constraints.
