Product details
Overview
DG202CSE+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 RDS(ON), guaranteed break-before-make switching, <1nA OFF-leakage at ±14V, and TTL/CMOS-compatible control inputs. It is used in programmable gain amplifiers and automatic test equipment where rail-to-rail analog signal integrity and latch-up immunity are required.
For engineers reviewing the DG202CSE+T datasheet, DG202CSE+T pinout, DG202CSE+T application, or DG202CSE+T equivalent, this page delivers verified electrical parameters, SO-16 package details, real-world use cases, and two validated alternative parts with documented functional and application differences.
Technical Context
The DG202CSE+T implements four independent CMOS transmission gates with inverted logic control (low = ON), enabling direct interface with standard digital controllers without external inverters. Each switch supports analog signals from –15V to +15V and maintains constant on-resistance across the full voltage range when powered from ±15V supplies.
It eliminates the need for a third logic supply (VL) required by legacy equivalents, simplifying power architecture. Its nonlatching behavior under signal-present power-off conditions ensures system robustness during hot-swap or brownout events in industrial and telecom infrastructure.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail analog signals without clipping in ±15V systems. |
| RDS(ON) | 175Ω max - Low on-resistance minimizes signal attenuation and gain error in precision amplifier paths. |
| OFF-Leakage Current | ±5nA max at ±14V - Ensures minimal DC error in high-impedance sample/hold and sensor multiplexing. |
| Switching Time (tON/tOFF) | 480ns / 370ns - Enables reliable operation up to ~1MHz multiplexing rates in ATE and comm systems. |
| Power Supply Range | ±4.5V to ±18V - Allows flexible biasing in battery-powered portable instruments and wide-range industrial rails. |
| Charge Injection | 20pC - Limits voltage glitch in sample-and-hold circuits, reducing need for large hold capacitors. |
| OFF-Isolation | 70dB - Provides strong channel-to-channel crosstalk suppression in multi-channel signal routing. |
Pinout & Package
Package: 16-pin SOIC (SO) with standard .150" width, JEDEC MS-012 outline, RoHS-compliant, tape-and-reel packaging (DG202CSE+T).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs: low voltage turns corresponding switch ON (normally open topology). |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - bidirectional analog I/O nodes; connect to signal sources or loads. |
| 3, 6, 11, 14 | S1–S4 | Source terminals - bidirectional analog I/O nodes; paired with D pins per switch. |
| 4 | V− | Negative supply rail input - must be connected to system V−; substrate reference for NMOS switches. |
| 5 | GND | Digital ground reference - ties logic threshold and internal bias networks. |
| 12 | N.C. | No connection - internally unconnected; leave floating or tie to GND per layout best practice. |
| 13 | V+ | Positive supply rail input - connects to system V+; also tied to substrate for PMOS switches. |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates dedicated logic rail - reduces BOM count and PCB routing complexity vs. DG212-class predecessors. |
| Guaranteed break-before-make | Prevents momentary short-circuit between channels during state transitions - critical for fault-tolerant multiplexing. |
| Nonlatching under signal-present power-off | Withstands input signals up to ±14V while V+/V− are disconnected - avoids destructive latch-up in hot-plug scenarios. |
| Constant RDS(ON) over signal range | Minimizes THD and gain nonlinearity in audio and instrumentation paths - no trimming needed across ±10V swing. |
| CMOS/TTL logic compatible | Accepts 0.8V/2.4V thresholds - interoperates directly with microcontrollers, FPGAs, and legacy logic families. |
Applications
| Programmable Gain Amplifier | Analog Multiplexer |
|---|---|
Use Scenario: Selecting feedback resistor values in op-amp-based PGA to achieve discrete gain steps (e.g., 1×, 2×, 5×, 10×). IC Role / Device Role / Timing Role: Quad SPST switch routing analog feedback paths; operates statically (no high-speed toggling required). Use Value: Maintains <0.01% gain error due to low and stable RDS(ON), and adds no offset to output signal. |
Use Scenario: Routing multiple sensor outputs (e.g., thermocouples, strain gauges) to a single ADC input in data acquisition systems. IC Role / Device Role / Timing Role: Analog signal selector with channel isolation >70dB to prevent cross-talk between high-impedance sensors. Use Value: Sub-nA OFF-leakage preserves accuracy in µV-level measurements; ±15V range accommodates unconditioned sensor outputs. |
| Automatic Test Equipment | Communications Systems |
Use Scenario: Configuring signal paths in modular ATE fixtures for functional testing of mixed-signal boards. IC Role / Device Role / Timing Role: High-voltage analog switch enabling stimulus routing and response capture across ±12V DUT interfaces. Use Value: ±18V continuous operation supports wide compliance ranges; fast 370ns tOFF enables high-throughput test sequencing. |
Use Scenario: Signal path selection in PBX/PABX line cards for voice channel routing and loopback diagnostics. IC Role / Device Role / Timing Role: Bidirectional analog switch handling AC-coupled voice signals (20Hz–3.4kHz) with minimal distortion. Use Value: Low charge injection (20pC) prevents audible click/pop artifacts during call setup; rail-to-rail support handles ±12V signaling. |
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 typ), but limited to ±5.5V supplies; requires external level-shifting for ±15V systems. | Better for low-voltage portable gear; unsuitable for industrial ±15V signal chains without redesign. | Select MAX4617ESE+ only if supply rails ≤±5.5V and on-resistance <100Ω is mandatory. |
| ADG1412BRUZ | Higher supply range (±15V), 1.8Ω RDS(ON), but requires VL = 3.3V/5V logic supply and has higher leakage (±20nA). | Preferred for ultra-low-distortion audio routing; less suitable for high-isolation, low-leakage sample/holds. | Choose ADG1412BRUZ when sub-2Ω on-resistance justifies added VL rail and leakage tolerance. |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG202CSE+T uniquely balances wide ±18V operation, no-VL simplicity, and sub-5nA leakage - making it optimal for industrial ATE and programmable gain stages where supply flexibility and DC precision are co-priorities.

FAQ
What is the maximum continuous supply voltage range supported by the DG202CSE+T?
The DG202CSE+T supports continuous operation from ±4.5V to ±18V. This is explicitly guaranteed in the Absolute Maximum Ratings and Electrical Characteristics tables for both DG202 and DG212 families. Operation beyond ±18V risks permanent damage, and performance parameters like RDS(ON) are characterized only within this range.
Does the DG202CSE+T require a separate logic supply (VL) pin?
No, the DG202CSE+T does not require a VL supply. Unlike the original DG212, Maxim eliminated the VL pin while maintaining TTL/CMOS compatibility - all logic inputs operate directly from the same V+ and V− rails. Pin 12 is marked N.C., confirming no third supply is needed.
What is the guaranteed RDS(ON) for the DG202CSE+T at ±15V supplies?
At ±15V supplies, the DG202CSE+T guarantees a maximum RDS(ON) of 175Ω (typical 115Ω) when VD = ±10V, VIN = 2.4V, and IS = 1mA. This value is confirmed in the DG202 Electrical Characteristics table under "DG202C, D, E" grade specifications.
How does the DG202CSE+T behave when power supplies are disconnected but analog signals remain present?
The DG202CSE+T is guaranteed nonlatching under those conditions. Internal protection diodes clamp signals exceeding V+ or V−, and current is internally limited to 25mA. This behavior is explicitly stated in the General Description and Protecting Against Fault Conditions section, ensuring safe operation during hot-swap or brownout events.
What is the pin-compatible replacement for DG202CSE+T in SO-16 package?
The DG202CSE+T has no pin-compatible drop-in replacement - its inverted logic control (low = ON) distinguishes it from DG201/DG211 variants. The DG202CSE+T shares the same SO-16 footprint and pinout with DG212CSE+, but DG212 uses non-inverted logic. Swapping requires logic inversion in the controller firmware or hardware.
