Product details
Overview
DG201ACJ+ from Maxim Integrated is a quad SPST normally closed analog switch IC designed for precision signal routing in ±4.5V to ±18V dual-supply systems. It features guaranteed break-before-make switching, 450ns max turn-off time, 600ns max turn-on time, and 115Ω typical RDS(ON) at ±15V, enabling low-distortion signal path control in test equipment and communications systems.
For engineers reviewing the DG201ACJ+ datasheet, DG201ACJ+ pinout, DG201ACJ+ application, or DG201ACJ+ equivalent, this device supports high-voltage analog switching with latch-up immunity during supply disconnection, CMOS/TTL logic compatibility, and no VL supply requirement-key selection criteria for portable and military-grade signal routing designs.
Technical Context
The DG201ACJ+ implements monolithic CMOS architecture with four independent SPST switches, each controlled by dedicated logic inputs (IN1–IN4). Its internal structure ensures nonlatching behavior when power supplies are removed while analog signals remain present, eliminating destructive current paths through substrate diodes.
Switching performance is defined by precise timing parameters: tON ≤ 600ns and tOFF ≤ 450ns under VS = 2V, RL = 1kΩ, CL = 35pF conditions. Analog signal range spans ±15V with 70dB OFF-isolation and 90dB crosstalk rejection, supporting high-fidelity channel separation in multi-channel instrumentation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports full-rail signal switching across industrial and military voltage ranges without clipping. |
| RDS(ON) | 115Ω (typ), 175Ω (max) at ±15V - Ensures minimal insertion loss and distortion in precision analog paths. |
| Turn-Off Time | ≤ 450ns - Enables fast channel isolation critical in automated test equipment sequencing. |
| Turn-On Time | ≤ 600ns - Maintains tight timing margins in synchronized multi-switch applications like PBX line routing. |
| OFF-Isolation | 70dB at 100kHz - Prevents signal bleed between inactive channels in sensitive guidance system front-ends. |
| Crosstalk | 90dB at 100kHz - Guarantees channel-to-channel signal integrity in head-up display video multiplexing. |
| Supply Range | ±4.5V to ±18V continuous - Allows operation from standard ±5V, ±12V, or ±15V rails without external regulation. |
| Logic Compatibility | CMOS/TTL - Interfaces directly with microcontrollers and FPGAs without level-shifting circuitry. |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), JEDEC MS-001, RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Independent logic inputs controlling respective SPST switches; active-high enables conduction. |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - connect to signal sources or downstream loads in bidirectional analog paths. |
| 3, 6, 11, 14 | S1–S4 | Source terminals - form complementary connection points for analog signal routing networks. |
| 4 | V− | Negative supply rail input - must be connected to system −VSS; substrate tie point for dual-supply operation. |
| 5 | GND | Analog/digital reference ground - common return for logic and analog sections; requires low-impedance PCB plane. |
| 12 | N.C. | No internal connection - left unconnected on PCB; no electrical function or thermal role. |
| 13 | V+ | Positive supply rail input - connects to +VDD; also tied to substrate for ESD robustness and latch-up immunity. |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third power rail dependency versus legacy DG211, simplifying board layout and reducing BOM count. |
| Guaranteed break-before-make | Prevents momentary short-circuits during channel transitions, essential for protecting sensitive DAC/ADC interfaces. |

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+ | Single-pole double-throw (SPDT), 100Ω RDS(ON), 3.3V/5V single-supply only | Requires level-shifting for ±15V signal paths; lacks dual-supply capability and latch-up immunity | Select when space-constrained PCBs need SPDT topology and system operates exclusively from 3.3V/5V rails. |
| ADG1412BRUZ | Quad SPST, 1.8Ω RDS(ON), ±15V supply, but 10µA max IINL vs. DG201ACJ+'s 1µA | Better ON-resistance but higher logic input leakage; not rated for −55°C operation | Choose for ultra-low-loss audio or precision instrumentation where sub-2Ω resistance outweighs temperature range needs. |
Compared with MAX4617CSE+ and ADG1412BRUZ, the DG201ACJ+ uniquely delivers guaranteed break-before-make timing, no-VL-supply simplicity, and proven nonlatching operation across its full −40°C to +85°C industrial temperature range-making it the preferred choice for mission-critical analog routing where supply interruption resilience is mandatory.

FAQ
What is the maximum analog signal voltage range supported by the DG201ACJ+?
The DG201ACJ+ supports an analog signal range of ±15V when operated with ±15V supplies. Its absolute maximum ratings allow continuous operation from ±4.5V to ±18V, and the device maintains specified RDS(ON) and leakage performance across this full range. This makes DG201ACJ+ suitable for industrial control and test equipment interfacing with legacy ±12V or ±15V signal chains without attenuation or level-shifting.
Does the DG201ACJ+ require a separate VL logic supply voltage?
No, the DG201ACJ+ does not require a VL supply. Unlike earlier analog switches such as the DG211, Maxim eliminated the third power rail requirement for DG201ACJ+, enabling direct interface with standard CMOS/TTL logic levels using only V+ and V−. This simplifies power design, reduces component count, and improves reliability in portable and field-deployable systems where supply rail minimization is critical.
How does the DG201ACJ+ prevent latch-up when power supplies are disconnected?
The DG201ACJ+ incorporates internal protection that guarantees nonlatching behavior even when V+ and V− are turned off while analog signals remain present at S or D terminals. Internal clamping diodes limit current to 25mA, and the monolithic CMOS process eliminates parasitic SCR structures. This feature is validated per Maxim's absolute maximum ratings and is critical for DG201ACJ+ deployment in military radios and avionics where unexpected power cycling occurs.
What is the pin-compatible alternative to the DG201ACJ+ in SO or TSSOP packages?
The DG201ACSE+ (16-pin SO) and DG201ACUE+ (16-pin TSSOP) share identical electrical specifications, timing, and pinout with the DG201ACJ+, differing only in package type. All three variants use the same logic input mapping (IN1–IN4 on pins 1/8/9/16), drain/source assignments, and supply connections (V+ on pin 13, V− on pin 4, GND on pin 5). No PCB redesign is needed when migrating from DG201ACJ+ to either surface-mount variant.
What is the typical charge injection value for the DG201ACJ+, and why does it matter?
The DG201ACJ+ has a typical charge injection of 20pC, measured with CL = 1000pF and zero-source impedance. This low value minimizes output voltage glitches during switching transitions, which is essential in sample-and-hold circuits, programmable gain amplifiers, and precision sensor multiplexers. In applications like DG201ACJ+-based data acquisition front-ends, 20pC injection enables sub-12-bit accuracy without additional settling compensation.
