Product details
Overview
DG211EUE+T from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage bipolar signal routing in precision instrumentation and test systems. It operates over ±4.5V to ±18V supplies, delivers 175Ω max RDS(ON) at ±15V, exhibits 1000ns max turn-on time, and supports analog signal ranges up to ±15V - enabling reliable switching of audio, sensor, and control signals in military radios and PBX equipment.
For engineers reviewing the DG211EUE+T datasheet, DG211EUE+T pinout, DG211EUE+T application, or DG211EUE+T equivalent, key selection criteria include guaranteed break-before-make timing, no VL supply requirement, nonlatching behavior under powered-off signal conditions, and TSSOP-16 packaging compatible with automated SMT assembly for industrial and aerospace-grade designs.
Technical Context
The DG211EUE+T implements four independent CMOS SPST switches with complementary logic inputs driving transmission gates. Each switch features internal level-shifting circuitry eliminating the need for a separate VL supply, unlike legacy DG211 variants.
Its ±18V absolute maximum rating enables operation across wide analog signal swings, while guaranteed break-before-make timing (tOFF1 ≤ 500ns, tON ≤ 1000ns) prevents momentary shorting during channel transitions - critical for protecting sensitive downstream circuitry in guidance and control systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail bipolar signal routing without clipping in ±15V systems |
| RDS(ON) Max | 175Ω at VD = ±10V - ensures low insertion loss and minimal signal distortion for precision DC/low-frequency AC paths |
| Turn-On Time Max | 1000ns - defines minimum channel settling time for digital-controlled analog multiplexing |
| Turn-Off Time Max | 500ns - guarantees fast channel isolation to prevent crosstalk in time-critical sampling applications |
| Supply Range | ±4.5V to ±18V - enables direct integration into legacy ±12V and ±15V industrial power rails |
| OFF-Isolation | 70dB at 100kHz - suppresses unwanted coupling between active and inactive channels in multi-channel test fixtures |
| Channel Capacitance | 16pF (CD+S(ON)) - minimizes capacitive loading on high-impedance sources such as piezoelectric sensors |
Pinout & Package
Package: 16-pin TSSOP (4.4mm body width), RoHS-compliant, lead-free, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS/TTL-compatible logic inputs controlling respective SPST switch states (active-high) |
| 2, 15, 10, 7 | D1–D4 | Drain terminals - connect to load side of switched analog path; rated for ±15V continuous voltage |
| 3, 14, 11, 6 | S1–S4 | Source terminals - connect to signal source side; symmetric with drain for bidirectional analog conduction |
| 4 | V− | Negative supply rail input - must be connected to system −15V (or −4.5V to −18V) for proper biasing |
| 5 | GND | Digital ground reference - isolated from analog signal paths but tied to substrate via V+ connection |
| 12 | N.C. | No internal connection - left unconnected; not usable as thermal pad or auxiliary terminal |
| 13 | V+ | Positive supply rail input - connected internally to substrate; requires +4.5V to +18V relative to V− |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates external 5V rail and associated decoupling, reducing BOM count and PCB area in portable and space-constrained systems |
| Guaranteed break-before-make | Prevents transient short-circuits during channel switching - essential for protecting DAC outputs and sensor front-ends |
| Nonlatching under signal-present power-off | Allows safe hot-swap of analog signal sources even when V+ and V− are disconnected - critical for field-replaceable modules |
| CMOS/TTL logic compatibility | Accepts 0.8V/2.4V logic thresholds directly from microcontrollers and FPGAs without level-shifting circuitry |
| Monolithic low-power design | Draws only 0.4mA total supply current - extends battery life in handheld test equipment and avionics displays |

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+ | Lower RDS(ON) (60Ω), but limited to ±5.5V supplies and single-supply operation only | Better for low-voltage portable instruments; unsuitable for ±12V/±15V legacy systems | Select MAX4617ESE+ only when supply rails are ≤ ±5.5V and sub-100Ω ON-resistance is mandatory |
| ADG1412BRUZ | Higher voltage rating (±20V), lower leakage (0.1nA), but requires VL supply and has slower turn-off (650ns) | Preferred for ultra-low-leakage medical sensor interfaces; adds complexity due to VL rail | Choose ADG1412BRUZ when <1nA OFF-leakage is required and VL supply infrastructure already exists |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG211EUE+T uniquely balances ±18V operation, no-VL simplicity, and guaranteed break-before-make timing - making it optimal for retrofitting legacy ±15V test and comms hardware without board redesign.

FAQ
What is the operating temperature range for DG211EUE+T?
The DG211EUE+T is rated for −40°C to +85°C operation, matching the DG211E grade specification. This extended industrial temperature range ensures stable performance in harsh environments such as vehicle-mounted radios, outdoor test gear, and avionics subsystems where ambient temperatures fluctuate widely. The TSSOP package maintains thermal integrity across this full range without derating.
Does DG211EUE+T require a VL supply voltage?
No, DG211EUE+T does not require a VL supply. Unlike earlier DG211 variants from other manufacturers, Maxim's implementation eliminates the third supply rail through integrated level-shifting circuitry. This simplifies power architecture, reduces component count, and improves reliability - a key differentiator confirmed in the device's General Description and Pin Description sections.
What is the maximum analog signal voltage supported by DG211EUE+T?
The DG211EUE+T supports analog signals from −15V to +15V, as specified in its VANALOG parameter under Electrical Characteristics. This ±15V range is fully compatible with standard industrial and military signal conditioning circuits. Absolute maximum ratings extend to ±18V, allowing margin for transient overvoltage events without damage.
How does DG211EUE+T ensure break-before-make switching?
DG211EUE+T guarantees break-before-make timing per datasheet specifications: maximum turn-off time tOFF1 is 500ns and maximum turn-on time tON is 1000ns. This timing asymmetry ensures that an output channel is fully disconnected before the next channel connects - preventing momentary shorts in multi-source analog multiplexers used in disk drive servo loops and test fixture calibration paths.
Is DG211EUE+T pin-compatible with DG201AEUE?
No, DG211EUE+T is not pin-compatible with DG201AEUE. Although both are 16-pin TSSOP quad SPST switches, their pin functions differ: DG201A assigns IN1–IN4 to pins 1, 2, 3, 4, whereas DG211 uses pins 1, 8, 9, 16 for logic inputs. Substituting DG211EUE+T for DG201AEUE would require PCB layout revision and firmware logic inversion to match the inverted control mapping.
