Product details
Overview
DG211CSE 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 and test equipment where rail-to-rail analog signal integrity is critical.
For engineers reviewing the DG211CSE datasheet, DG211CSE pinout, DG211CSE application, or DG211CSE equivalent, this page delivers verified electrical parameters, SO package mechanical data, real-world leakage and timing specs, and two validated alternative parts for design continuity and sourcing flexibility.
Technical Context
The DG211CSE implements four independent CMOS SPST switches with logic-compatible control inputs (TTL/CMOS), no VL supply requirement, and nonlatching behavior when power supplies are disconnected while analog signals remain present. Its monolithic structure ensures matched channel characteristics and low crosstalk (90dB).
Switching is controlled by four digital inputs (IN1–IN4) that drive internal gate drivers; each switch connects source (Sx) to drain (Dx) when logic low (0V), and opens when logic high (≥2.4V). Analog signal range spans ±15V with guaranteed operation down to ±4.5V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail analog signals 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 switched analog waveforms |
| OFF-Isolation | 70dB - suppresses signal coupling between inactive and active channels |
| Supply Range | ±4.5V to ±18V - enables use in legacy industrial and telecom power architectures |
| Logic Compatibility | CMOS/TTL - interfaces directly with microcontrollers and FPGA I/O without level shifters |
| Channel Count | 4 independent SPST switches - provides compact multiplexing or signal gating in space-constrained designs |
Pinout & Package
Package: 16-pin SOIC (Small Outline Integrated Circuit), 0.150" wide body, JEDEC MS-012 standard, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs; low = switch closed (normally closed), high = open |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - analog signal output side of each SPST switch |
| 3, 6, 11, 14 | S1–S4 | Source terminals - analog signal input side of each SPST switch |
| 4 | V− | Negative supply rail - must be connected to system −VDD or −15V |
| 5 | GND | Ground reference - common return for logic and substrate bias |
| 12 | N.C. | No connection - internally unconnected; must be left floating or tied to GND |
| 13 | V+ | Positive supply rail - connected to substrate; must be tied to +VDD or +15V |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail - simplifies PCB layout and reduces BOM count vs. legacy DG211 variants |
| Guaranteed break-before-make | Prevents momentary short-circuits during channel switching - essential for fault-tolerant analog routing |
| Nonlatching under signal-present power-off | Remains electrically stable when V+/V− are removed while analog inputs remain active - avoids destructive latch-up |
| Low OFF-leakage (±5nA max) | Minimizes DC error in high-impedance sensor or precision measurement paths |
| Low ON-capacitance (16pF) | Preserves bandwidth and reduces settling time in fast-switching analog applications |

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 |
|---|---|---|---|
| MAX4617CSE+ | Lower RDS(ON) (60Ω), faster tON (150ns), but only ±5V supply range | Better for low-voltage, high-speed data acquisition; unsuitable for ±15V telecom or military systems | Select MAX4617CSE+ only if supply rails ≤±5V and speed >1000ns is required |
| ADG1412BRUZ | Higher voltage rating (±20V), lower leakage (±0.5nA), but requires VL supply and has slower tOFF (250ns) | Preferred for ultra-low-leakage medical instrumentation; VL dependency adds complexity vs. DG211CSE | Choose ADG1412BRUZ when sub-nA leakage is mandatory and VL rail can be accommodated |
Compared with MAX4617CSE+ and ADG1412BRUZ, the DG211CSE uniquely balances wide supply range (±4.5V to ±18V), no-VL simplicity, and robust ±15V analog handling - making it optimal for legacy industrial and telecom infrastructure where rail compatibility and reliability outweigh raw speed or ultra-low leakage.

FAQ
What is the maximum analog signal voltage supported by the DG211CSE?
The DG211CSE supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow continuous operation up to ±18V supplies, and the analog signal can swing rail-to-rail within the supply rails - meaning the DG211CSE handles signals from V− to V+ without clipping or damage, provided the supply voltages remain within specification.
Does the DG211CSE require a VL logic supply pin?
No, the DG211CSE does not require a VL supply pin. Unlike earlier generations of the DG211 family, Maxim's DG211CSE eliminates the need for a separate logic supply - all logic inputs (IN1–IN4) operate directly from the main V+ and V− rails and are compatible with standard TTL and CMOS logic levels. This simplifies power architecture and reduces external component count compared to legacy versions.
What is the guaranteed RDS(ON) for DG211CSE at ±12V supplies?
The DG211CSE datasheet specifies a maximum RDS(ON) of 175Ω at ±15V supplies. At ±12V, typical RDS(ON) increases to approximately 200Ω based on the published RDS(ON) vs. supply curve - however, Maxim does not guarantee a specific maximum value at ±12V. For design margin, engineers should use the ±15V spec (175Ω) or consult the "RDS(ON) AT ANALOG SIGNAL LEVEL" graph in the DG211CSE datasheet.
Can DG211CSE be used in a single-supply configuration?
No, the DG211CSE is designed exclusively for dual-supply operation (±4.5V to ±18V). It lacks internal level-shifting or charge-pump circuitry to support single-supply use. Attempting to operate the DG211CSE with only V+ and GND (or V− and GND) will result in improper switching behavior and potential damage due to violation of absolute maximum ratings on V− and GND pins.
What is the operating temperature range for DG211CSE?
The DG211CSE is rated for commercial temperature operation from 0°C to +70°C. This is explicitly defined in the Ordering Information table, where "DG211CSE" corresponds to the "C" grade suffix. It is not qualified for extended industrial (−40°C to +85°C) or military (−55°C to +125°C) temperature ranges - those require variants like DG211DY or DG211AK.
