Product details
Overview
DG212CSE+T from Maxim Integrated is a quad SPST normally open analog switch IC designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features 175Ω typical on-resistance, <5nA off-leakage at ±14V, 460ns turn-on time, and guaranteed break-before-make switching. It serves as a precision signal path selector in programmable gain amplifiers and automatic test equipment.
For engineers reviewing the DG212CSE+T datasheet, DG212CSE+T pinout, DG212CSE+T application, or DG212CSE+T equivalent, this page delivers verified electrical parameters, SOIC-16 package details, real-world use scenarios, and two validated alternative parts with functional and application-level distinctions.
Technical Context
The DG212CSE+T implements four independent CMOS SPST switches with inverted logic control inputs-distinct from the DG202 family-and operates without a separate VL logic supply. Its monolithic design ensures nonlatching behavior even when power supplies are disconnected while analog signals remain present.
Each switch supports rail-to-rail analog signal ranges (±15V), exhibits constant RDS(ON) over the full signal swing, and maintains low charge injection (20pC) and channel capacitance (16pF). All terminals tolerate ±44V differential stress between V+ and V−.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports full-rail signal switching across dual supplies without clipping or distortion. |
| RDS(ON) | 115Ω to 175Ω - Low, stable on-resistance enables minimal signal attenuation in precision analog paths. |
| Off-Leakage Current | <±5.0nA at ±14V - Ensures high isolation and low DC error in sample/hold and multiplexer applications. |
| Turn-On/Off Time | 460ns / 360ns - Fast switching supports moderate-speed data acquisition and communications signal routing. |
| Supply Range | ±4.5V to ±18V - Enables operation from standard ±5V, ±12V, and ±15V industrial and test equipment rails. |
| Logic Compatibility | CMOS/TTL - Accepts 0.8V/2.4V logic thresholds directly from microcontrollers or FPGAs without level-shifting. |
| Power Supply Current | 0.02mA to 0.4mA - Ultra-low quiescent current supports battery-powered portable instrumentation. |
Pinout & Package
DG212CSE+T is housed in a 16-pin SOIC (Small Outline Integrated Circuit) package with 1.27mm pitch, JEDEC MS-012 compliant outline, and exposed pad not present in this variant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs: low = switch ON (normally open), high = OFF. |
| 2, 15, 10, 7 | D1–D4 | Drain terminals - bidirectional analog signal outputs connected to load or downstream circuitry. |
| 3, 14, 11, 6 | S1–S4 | Source terminals - bidirectional analog signal inputs connected to sources or upstream circuitry. |
| 4 | V− | Negative supply rail input - must be connected to system −V rail (e.g., −15V). |
| 5 | GND | Digital ground reference - tied to system digital ground plane. |
| 12 | N.C. | No internal connection - left unconnected per datasheet; no PCB trace required. |
| 13 | V+ | Positive supply rail input - connected to substrate and must be tied to +V rail (e.g., +15V). |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third logic rail dependency, simplifying power architecture versus legacy DG212 equivalents. |
| Guaranteed break-before-make | Prevents momentary shorting during channel switching - critical for avoiding signal glitches in multiplexed systems. |
| Nonlatching under fault conditions | Remains functional and undamaged when analog inputs persist during power-down - enhances system robustness. |
| Bidirectional conduction | Enables flexible signal routing regardless of source/sink direction - ideal for shared analog buses. |
| Constant RDS(ON) vs. signal voltage | Maintains linear gain and low THD in programmable gain amplifier topologies across full ±15V range. |
Applications
| Programmable Gain Amplifier | Analog Multiplexer |
|---|---|

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; 60Ω RDS(ON); requires VL supply. | Limited to unipolar systems; unsuitable for ±15V signal routing or bipolar instrumentation. | Select when operating from +5V/+12V only and lower on-resistance is prioritized over dual-supply flexibility. |
| ADG1412BRUZ | ±15V rated; 1.8Ω RDS(ON); 16-lead TSSOP; requires VL; higher supply current (1.2mA). | Superior on-resistance but incompatible pinout and higher power draw; lacks nonlatching guarantee under power-off. | Choose for ultra-low distortion audio or high-precision data acquisition where leakage and on-resistance dominate over fault tolerance. |
Compared with MAX4617ESE+ and ADG1412BRUZ, DG212CSE+T uniquely balances dual-supply robustness, zero-VL simplicity, and proven nonlatching behavior-making it optimal for portable test gear and industrial systems where supply sequencing cannot be guaranteed.

FAQ
What is the maximum allowable supply voltage for DG212CSE+T?
The DG212CSE+T supports continuous operation from ±4.5V to ±18V. Absolute maximum ratings allow up to ±25V on V+ and V− individually, and 44V differential between them. Exceeding ±18V continuously risks exceeding RDS(ON) specifications and thermal limits, so ±18V remains the functional upper bound per datasheet.
Does DG212CSE+T require a VL logic supply voltage?
No, DG212CSE+T does not require a VL supply. Unlike earlier DG212 variants from other manufacturers, Maxim's DG212CSE+T integrates logic level translation internally, accepting standard CMOS/TTL inputs directly from 0V/5V or 0V/3.3V controllers without an auxiliary VL rail.
How does DG212CSE+T behave when power supplies are disconnected while analog signals remain applied?
DG212CSE+T is guaranteed nonlatching under such fault conditions. Internal protection prevents parasitic SCR activation, allowing safe operation even when ±15V supplies are removed while ±14V analog signals persist on S/D pins - a key reliability feature confirmed in Maxim's absolute maximum ratings and application notes.
What is the pin-compatible replacement for DG212CSE+T in SOIC-16?
No pin-compatible drop-in replacement exists for DG212CSE+T due to its unique inverted logic control scheme and VL-free architecture. DG202CSE shares the same SOIC-16 pinout but uses non-inverted logic; substituting it requires inverting all four control signals in firmware or hardware.
What is the typical on-resistance variation across the analog signal range for DG212CSE+T?
DG212CSE+T exhibits essentially constant RDS(ON) across the full ±15V analog signal range. At ±15V supplies, RDS(ON) varies from 135Ω to 155Ω - a <15% spread - ensuring linear gain and minimal harmonic distortion in precision analog paths like programmable gain amplifiers.
