Product details
Overview
DG212CJ+ 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 guaranteed break-before-make switching, 175Ω typical on-resistance at ±15V, <5nA off-leakage, and TTL/CMOS-compatible control inputs - enabling use in programmable gain amplifiers and automatic test equipment.
For engineers reviewing the DG212CJ+ datasheet, DG212CJ+ pinout, DG212CJ+ application, or DG212CJ+ equivalent, key selection considerations include its 16-pin plastic DIP package, no-VL-supply operation, latch-up immunity during hot insertion, and compatibility with rail-to-rail analog signals up to ±15V.
Technical Context
The DG212CJ+ implements four independent CMOS transmission gates with inverted logic control inputs (active-low), distinguishing it from the DG202 series. Each switch provides symmetrical conduction, constant RDS(ON) across the analog range, and guaranteed nonlatching behavior when power supplies are removed while analog signals remain applied.
It operates without a separate logic supply (VL), simplifying system design versus legacy equivalents. Internal protection diodes clamp input overvoltage transients, and the monolithic CMOS process ensures low quiescent current (≤0.4mA total supply current) and minimal charge injection (20pC).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full rail-to-rail analog signal switching without clipping |
| RDS(ON) | 115Ω (min) to 175Ω (typ) at ±15V - ensures low insertion loss and minimal signal distortion |
| Off-Leakage Current | ±5.0nA max - preserves accuracy in high-impedance sample/hold and sensor interfaces |
| Turn-On/Off Time | 460ns / 450ns max - enables reliable operation in 1MHz sampling and multiplexing |
| Supply Range | ±4.5V to ±18V continuous - accommodates industrial and telecom voltage rails |
| Logic Compatibility | CMOS/TTL - interfaces directly with microcontrollers and FPGAs without level shifters |
| Charge Injection | 20pC - minimizes voltage step errors in precision sample-and-hold circuits |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), through-hole mount, RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Inverted logic control inputs - low = switch ON (normally open architecture) |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - bidirectional analog signal outputs connected to load side |
| 3, 6, 11, 14 | S1–S4 | Source terminals - bidirectional analog signal inputs connected to source side |
| 4 | V− | Negative supply rail - must be connected to system −VSS; substrate reference |
| 5 | GND | Digital ground - common reference for logic inputs and internal biasing |
| 12 | N.C. | No connection - internally unconnected; leave floating or unpopulated |
| 13 | V+ | Positive supply rail - connected to substrate; sets upper analog signal limit |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail - reduces BOM count and PCB routing complexity vs. legacy DG212 variants |
| Guaranteed break-before-make | Prevents momentary short-circuit between channels during switching - critical for multiplexer safety |
| Nonlatching under hot-insertion | Remains functional even if analog signals are present while V+/V− are powered down - enhances system robustness |
| Constant RDS(ON) vs. signal voltage | Minimizes harmonic distortion and THD in audio and instrumentation signal paths |
| Bidirectional analog conduction | Enables flexible signal routing - same device used for input or output switching without polarity constraints |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPE+ | Single SPST, 3.3V/5V only, no dual-supply support | Limited to low-voltage logic systems; cannot replace DG212CJ+ in ±15V analog paths | Select only for 3.3V/5V single-supply designs requiring lower RDS(ON) (0.5Ω) but sacrificing voltage range |
| ADG1412BRUZ | Quad SPST, ±15V rated, but requires VL supply and has higher leakage (±20nA) | Compatible pinout but needs external VL rail; less suitable for hot-swap scenarios | Use where higher channel count density (TSSOP-16) is prioritized over latch-up immunity and VL elimination |
Compared with MAX4617CPE+ and ADG1412BRUZ, the DG212CJ+ uniquely combines ±18V operation, no-VL architecture, and guaranteed nonlatching behavior - making it the only option among the three qualified for industrial dual-supply hot-plug analog routing.

FAQ
What is the operating temperature range for DG212CJ+?
The DG212CJ+ is rated for 0°C to +70°C ambient operation, matching the "C" grade specification in Maxim's ordering table. This range covers commercial and many industrial control applications where ambient temperatures remain within standard room-temperature envelopes. The device maintains specified RDS(ON), leakage, and timing performance across this full range without derating.
Does DG212CJ+ require a VL logic supply voltage?
No, DG212CJ+ does not require a VL supply. Unlike earlier DG212 variants and competing analog switches, it derives all logic-level translation internally from V+ and V−, eliminating the need for a third rail. This simplifies power architecture and reduces layout overhead - a key differentiator confirmed in Maxim's datasheet General Description and Electrical Characteristics sections.
How does DG212CJ+ handle power-down with live analog signals applied?
DG212CJ+ is guaranteed nonlatching when power supplies are disconnected while analog signals remain present - a feature explicitly validated in Maxim's Absolute Maximum Ratings and General Description. Internal protection structures prevent parasitic SCR activation, allowing safe hot-insertion into powered-backplane systems without risk of destructive latch-up.
What is the maximum analog signal voltage supported by DG212CJ+?
DG212CJ+ supports analog signals from V− to V+, with a guaranteed ±15V range per the Electrical Characteristics table. Its absolute maximum ratings allow V+ to V− up to 44V, meaning it can safely switch signals spanning up to ±22V when operated within thermal limits - though ±15V is the fully characterized and production-guaranteed range.
Is DG212CJ+ pin-compatible with DG202CJ?
No, DG212CJ+ and DG202CJ are not pin-compatible. While both are 16-pin DIP quad SPST switches, DG212 uses inverted logic inputs (low = ON), whereas DG202 uses non-inverted inputs (high = ON). Their pin functions differ: IN1–IN4 on DG212 occupy pins 1, 8, 9, 16, while DG202 places them on pins 1, 2, 3, 4 - requiring PCB redesign for substitution.
