Product details
Overview
DG211CUE+ from Maxim Integrated is a quad SPST normally closed analog switch IC designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features guaranteed break-before-make switching, 175Ω max RDS(ON) at ±15V, 1000ns max turn-on time, and operates across 0°C to +70°C - used in PBX systems, test equipment, and military radios where supply-disconnect robustness is critical.
For engineers reviewing the DG211CUE+ datasheet, DG211CUE+ pinout, DG211CUE+ application, or DG211CUE+ equivalent, key selection criteria include analog signal range (±15V), leakage performance (±5nA OFF-leakage), TSSOP-16 package compatibility, and absence of VL supply requirement compared to legacy DG211 variants.
Technical Context
The DG211CUE+ implements four independent CMOS SPST switches with integrated logic-level translation, enabling TTL/CMOS-compatible control without external level shifters. Its monolithic design eliminates latch-up risk even when power supplies are disconnected while analog signals remain applied.
Switching behavior is defined by guaranteed break-before-make timing, with tON ≤ 1000ns and tOFF ≤ 500ns under VS = 2V, RL = 1kΩ, CL = 35pF conditions. Analog signal handling supports full ±15V range with channel capacitance of 16pF (CD+S(ON)) and 5pF OFF-capacitance per terminal.
Key Specifications

|---|---|
| Analog Signal Range | ±15V - supports rail-to-rail analog signal switching without clipping in ±15V systems |
| RDS(ON) Max | 175Ω at VD = ±10V, IS = 1mA - ensures low insertion loss for precision signal paths |
| Turn-On Time Max | 1000ns - defines minimum pulse width support for digital control of analog signals |
| OFF-Leakage Current | ±5nA at VS/VD = ±14V - maintains signal integrity in high-impedance sensor or reference circuits |
| Supply Range | ±4.5V to ±18V continuous - enables operation across industrial, telecom, and military voltage rails |

| 3, 6, 11, 14 | S1–S4 | Source terminals - analog signal inputs from source or previous stage |
| 4 | V− | Negative supply rail input - connects to −15V or other negative bias |

Key Features
| Feature | Design Value |
|---|---|

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-pole double-throw (SPDT), 100Ω RDS(ON), +3V to +16V single-supply only | Requires redesign for SPDT topology and lacks negative supply support | Select only if system uses single-supply architecture and SPDT functionality is needed |
| ADG1412YRUZ | Quad SPST, 1.8Ω RDS(ON), ±15V supply, but requires VL bias and has 125°C max temp rating | Higher performance ON-resistance but adds VL supply complexity and exceeds commercial temp range | Choose for ultra-low distortion audio paths where VL supply overhead is acceptable |
Compared with DG211CUE+, MAX4617ESE+ offers lower RDS(ON) but mandates SPDT rework and loses bipolar supply capability, while ADG1412YRUZ delivers superior ON-resistance yet reintroduces the VL supply dependency DG211CUE+ was engineered to eliminate.

FAQ
What is the maximum analog signal voltage range supported by DG211CUE+?
The DG211CUE+ supports an analog signal range of ±15V when operated with ±15V supplies. This is specified under VANALOG in the Electrical Characteristics table and applies across the full 0°C to +70°C operating temperature range. The device maintains this range without clipping or distortion, making DG211CUE+ suitable for legacy industrial and defense systems using standard bipolar rails.
Does DG211CUE+ require a VL supply pin like some older analog switches?
No, DG211CUE+ does not require a VL supply pin. Unlike earlier DG211 variants from the original manufacturer, Maxim's DG211CUE+ eliminates the need for a third logic supply rail. All logic interface functions operate directly from the main V+ and V− supplies, simplifying power design and reducing component count - a key differentiator confirmed in the Features section of the datasheet.
What is the guaranteed RDS(ON) for DG211CUE+ at ±15V supplies?
The guaranteed maximum RDS(ON) for DG211CUE+ is 175Ω under test conditions of VD = ±10V, VIN = 0.8V, and IS = 1mA. This value is specified in the DG211 Electrical Characteristics table and reflects worst-case conduction resistance across temperature and process variation - critical for calculating insertion loss in precision analog paths using DG211CUE+.
Is DG211CUE+ pin-compatible with DG201ACUE+?
No, DG211CUE+ is not pin-compatible with DG201ACUE+. Although both use the same TSSOP-16 package, their pin functions differ: DG201A assigns IN1–IN4 to pins 1, 2, 3, 4, whereas DG211CUE+ places IN1–IN4 on pins 1, 8, 9, 16. Substituting DG211CUE+ for DG201ACUE+ without PCB revision will result in incorrect logic control and signal routing failure.
What is the OFF-isolation performance of DG211CUE+ at 100kHz?
The OFF-isolation of DG211CUE+ is guaranteed at ≥70dB at 100kHz, measured with ZL = 75Ω. This parameter quantifies signal rejection between an OFF switch's source and drain terminals, ensuring minimal crosstalk in multiplexed signal chains. The value is consistent across both DG211 and DG201A families and is validated under standard test conditions per the datasheet.
