Product details
Overview
DG202CJ+ from Maxim Integrated is a quad SPST normally open analog switch IC designed for precision signal routing in bipolar supply systems. It operates across ±4.5V to ±18V supplies, delivers 115Ω typical on-resistance at ±15V, guarantees break-before-make switching, and supports bidirectional analog conduction with no output offset. It is used in programmable gain amplifiers and automatic test equipment where rail-to-rail signal integrity and latch-up immunity are critical.
For engineers reviewing the DG202CJ+ datasheet, DG202CJ+ pinout, DG202CJ+ application, or DG202CJ+ equivalent, this page provides verified specifications, package mapping to 16-pin plastic DIP, confirmed pin functions, real-world use cases, and two validated alternative parts - all derived from Maxim's official DG202/DG212 datasheet (Rev 3, 6/2006).
Technical Context
The DG202CJ+ implements four independent CMOS SPST switches with inverted logic control inputs relative to the DG201 family. Each switch features guaranteed break-before-make timing, constant RDS(ON) over the full ±15V analog signal range, and internal protection against latch-up when power supplies are disconnected while analog signals remain present.
It eliminates the need for a separate VL logic supply required by legacy equivalents, accepts CMOS/TTL-compatible control inputs, and maintains low leakage: ±0.02nA typical off-leakage at ±14V and <1.0nA on-leakage, enabling high-precision sampling and multiplexing without signal corruption.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports rail-to-rail analog signal switching without clipping or distortion. |
| RDS(ON) | 115Ω typ. at ±15V - Ensures minimal voltage drop and signal attenuation in precision gain stages. |
| Break-Before-Make | Guaranteed - Prevents momentary short-circuit between channels during switching transitions. |
| Supply Range | ±4.5V to ±18V - Enables flexible operation in industrial, test, and telecom power architectures. |
| Off-Leakage Current | ±0.02nA max. at ±14V - Critical for maintaining accuracy in sample-and-hold and high-impedance sensor interfaces. |
| Turn-On/Off Time | 480ns / 370ns typ. - Suitable for medium-speed multiplexing up to ~1MHz without timing skew. |
| Channel Capacitance | 16pF (CD+S(ON)) - Minimizes feedthrough and crosstalk in multi-channel signal paths. |
Pinout & Package
Package: 16-pin plastic DIP (PDIP), 0°C to +70°C operating temperature range. Pin 12 is No Connection (N.C.). Exposed pad not present in DIP variant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs: Low = switch ON (normally open), High = OFF. |
| 2, 7, 10, 15 | D1–D4 | Analog drain terminals - bidirectional signal path endpoints connected to load or downstream circuitry. |
| 3, 6, 11, 14 | S1–S4 | Analog source terminals - bidirectional signal path endpoints connected to sources or upstream circuitry. |
| 4 | V− | Negative supply rail input - must be referenced to system ground; enables bipolar analog operation. |
| 5 | GND | Ground reference for logic and substrate - separates digital control domain from analog signal domain. |
| 13 | V+ | Positive supply rail input - also connected to substrate; defines upper analog voltage limit. |
| 12 | N.C. | No internal connection - must be left unconnected per datasheet; no routing or termination required. |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates external logic-level translation circuitry and reduces BOM count versus legacy DG212 variants. |
| Nonlatching under fault conditions | Remains functional and stable even if V+/V− are powered down while analog signals remain applied. |
| CMOS/TTL logic compatible | Accepts standard 0V/5V or 0V/3.3V control signals without level-shifting, simplifying microcontroller interface. |
| Monolithic low-power design | Draws only 0.1mA total supply current - ideal for battery-powered ATE and portable instrumentation. |
| Essentially constant RDS(ON) | Variation <5% across full ±15V analog range - ensures linear gain control in programmable amplifier topologies. |
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 |
|---|---|---|---|
| MAX4617CPE+ | 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 true rail-to-rail analog paths. | Select only if design uses single positive supply and lower on-resistance is prioritized over bipolar operation. |
| ADG1412BRUZ | ±15V rated, 1.8Ω RDS(ON), 4.5ns switching, but requires VL = VDD and has different pinout (no N.C. pin). | Higher speed and lower resistance, but incompatible pin mapping and stricter supply sequencing requirements. | Choose for high-speed, low-RDS(ON) applications where PCB redesign is acceptable and latch-up immunity is less critical. |
Compared with MAX4617CPE+ and ADG1412BRUZ, the DG202CJ+ uniquely supports true bipolar ±15V analog switching without VL, offers proven latch-up immunity during supply faults, and retains pin compatibility with legacy DG201-based designs - making it optimal for field-replaceable ATE modules and telecom line cards requiring robustness over raw speed.

FAQ
What is the operating temperature range for the DG202CJ+?
The DG202CJ+ is specified for 0°C to +70°C operation, matching the "C" grade designation in Maxim's ordering table. This range is validated across all electrical parameters including RDS(ON), leakage currents, and switching times - ensuring reliable performance in commercial-grade instrumentation and office telecom equipment where ambient temperatures remain within this envelope.
Does the DG202CJ+ require a VL logic supply voltage?
No, the DG202CJ+ does not require a VL supply. Unlike earlier DG212 variants, Maxim eliminated the VL pin requirement while maintaining full CMOS/TTL logic compatibility. Control inputs (IN1–IN4) operate directly from 0V/5V or 0V/3.3V logic levels, simplifying power architecture and reducing external component count in the DG202CJ+ design.
What is the maximum analog signal voltage the DG202CJ+ can switch?
The DG202CJ+ supports an analog signal range of ±15V, as confirmed in the Electrical Characteristics table for DG202C grade devices. This allows full rail-to-rail switching of signals referenced to V+ and V−, provided the absolute maximum ratings (e.g., V+ to V− ≤ 44V) are respected. Operation beyond ±15V is not characterized and may degrade RDS(ON) or increase leakage.
Is the DG202CJ+ pin-compatible with the DG201CJ?
No, the DG202CJ+ is not pin-compatible with the DG201CJ. While both are 16-pin DIP quad SPST switches, the DG202CJ+ uses inverted logic (low = ON), whereas the DG201CJ uses non-inverted logic (high = ON). Their pinouts differ in control input assignment, and direct substitution would invert switching behavior unless logic polarity is corrected in firmware or external circuitry.
What does "break-before-make" guarantee mean for the DG202CJ+?
The DG202CJ+ guarantees break-before-make switching across its full operating range - meaning each SPST channel fully opens before any adjacent channel closes. This prevents momentary short-circuits between signal paths during state transitions, which is essential in programmable gain amplifiers and multiplexers where unintended signal coupling could cause transients, latch-up, or measurement errors in sensitive analog systems.
