Product details
Overview
DG201ABJ-2 from Maxim Integrated is a quad SPST normally closed analog switch IC designed for high-voltage signal routing in precision instrumentation and military-grade systems. It operates across ±4.5V to ±18V dual supplies, delivers 115Ω typical RDS(ON) at ±15V, guarantees break-before-make switching, and supports -25°C to +85°C industrial temperature range in 16-pin PDIP package.
For engineers reviewing the DG201ABJ-2 datasheet, DG201ABJ-2 pinout, DG201ABJ-2 application, or DG201ABJ-2 equivalent, key selection criteria include guaranteed ±18V operation, 450ns max turn-off time, no VL supply requirement, and nonlatching behavior with powered-down supplies - critical for fault-tolerant analog front-ends in test equipment and avionics.
Technical Context
The DG201ABJ-2 implements monolithic CMOS architecture with integrated level-shifting logic to drive four independent SPST switches without external VL bias. Its internal protection diodes clamp input signals exceeding V+ or V−, limiting current to 25mA per terminal.
Switching performance is defined by guaranteed break-before-make timing (tOFF1 ≤ 450ns, tON ≤ 600ns), low charge injection (20pC), and analog signal range spanning ±15V - enabling accurate DC-coupled signal path control in ±15V systems such as guidance interfaces and PBX line cards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail signal switching in ±15V op-amp and DAC/ADC interface circuits |
| RDS(ON) | 115Ω typical at ±15V - ensures minimal voltage drop and THD degradation in audio and sensor signal paths |
| Turn-Off Time | ≤450ns - enables fast channel isolation in automated test equipment scan sequences |
| Supply Range | ±4.5V to ±18V - allows direct integration into legacy ±12V and ±15V industrial power domains |
| Off-Leakage Current | ±0.02µA max - preserves accuracy in high-impedance sensor multiplexing (e.g., thermocouple inputs) |
| Charge Injection | 20pC - limits voltage glitch on sampled-hold capacitors in data acquisition front-ends |
Pinout & Package
Package: 16-pin Plastic Dual In-line Package (PDIP), 0.300" wide, through-hole mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | Logic Input (IN1–IN4) | CMOS/TTL-compatible control lines; low = switch ON (normally closed) |
| 2, 7, 10, 15 | Drain (D1–D4) | Analog output node; connects to load or next stage when switch is closed |
| 3, 6, 11, 14 | Source (S1–S4) | Analog input node; connects to signal source (e.g., sensor, DAC output) |
| 4 | V− | Negative supply rail; must be connected to system −15V or −12V |
| 5 | GND | Circuit reference ground; separate from analog signal ground in mixed-signal layouts |
| 12 | N.C. | No internal connection; leave unconnected or tie to GND for mechanical stability |
| 13 | V+ | Positive supply rail; also tied to substrate for latch-up immunity |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates third bias rail, simplifying PCB layout and reducing BOM count vs. legacy DG211 |
| Nonlatching with powered-off supplies | Prevents destructive current flow when analog signals remain active during power-down cycles |
| Guaranteed break-before-make | Ensures no momentary short between channels during switching - critical for multi-channel mux safety |
| ±4.5V to ±18V operation | Supports direct use in both modern low-voltage and legacy high-voltage analog systems |
| CMOS/TTL logic compatibility | Accepts standard 0V/5V or 0V/3.3V control signals without level shifters |

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 |
|---|---|---|---|
| DG211CJ | Slower switching (tOFF ≤ 500ns, tON ≤ 1000ns); requires VL supply | Higher power consumption; less suitable for battery-powered portable test gear | Select DG211CJ only if VL rail already exists and speed requirements are relaxed |
| MAX4617CPE+ | Single-supply operation (up to 36V); 100Ω RDS(ON); no negative supply needed | Cannot handle bipolar analog signals; requires level-shifting for ±15V systems | Choose MAX4617CPE+ for unipolar high-voltage routing where negative rails are absent |
Compared with DG211CJ and MAX4617CPE+, the DG201ABJ-2 uniquely combines bipolar ±18V operation, no-VL architecture, and sub-500ns switching - making it the only drop-in solution for legacy ±15V military and industrial systems requiring guaranteed break-before-make and nonlatching behavior.

FAQ
What is the operating temperature range for DG201ABJ-2?
The DG201ABJ-2 is rated for -25°C to +85°C operation, validated per its CERDIP-compatible plastic DIP packaging and internal process characterization. This range supports deployment in industrial control cabinets and vehicle-mounted communications equipment where ambient temperatures exceed commercial-grade limits. The DG201ABJ-2 maintains specified RDS(ON), leakage, and timing parameters across this full span without derating.
Does DG201ABJ-2 require a VL supply voltage?
No, the DG201ABJ-2 does not require a VL supply. Unlike the original DG211, Maxim's DG201ABJ-2 integrates on-chip level-shifting circuitry that eliminates the need for a third bias rail. This reduces system complexity, PCB area, and BOM cost while improving reliability in field-deployed DG201ABJ-2 applications such as military radio front-ends and avionics sensor interfaces.
What is the maximum analog signal voltage the DG201ABJ-2 can switch?
The DG201ABJ-2 supports an analog signal range of ±15V, verified under ±15V supply conditions. Absolute maximum ratings allow VS or VD to reach ±14V relative to V−, and the device clamps input excursions beyond V+ or V− via internal diodes. This ±15V capability makes DG201ABJ-2 suitable for interfacing with legacy op-amps, DACs, and ADCs operating on standard bipolar rails.
How does DG201ABJ-2 prevent latch-up during power-down?
The DG201ABJ-2 uses a monolithic CMOS process with guard rings and substrate ties to V+ that guarantee nonlatching behavior even when V+ and V− are disconnected while analog signals remain present at S or D terminals. This intrinsic latch-up immunity is tested and guaranteed per JEDEC JESD78, ensuring safe operation in DG201ABJ-2 applications like guidance systems where power sequencing cannot be controlled.
Is DG201ABJ-2 pin-compatible with other DG201A variants?
Yes, DG201ABJ-2 shares identical 16-pin PDIP pinout and electrical characteristics with all other DG201A variants (e.g., DG201ACJ, DG201ADJ), differing only in temperature grade (-25°C to +85°C). Layouts designed for DG201ACJ (0°C to +70°C) or DG201ADJ (-40°C to +85°C) require no changes to accommodate DG201ABJ-2, enabling seamless qualification upgrades in existing DG201ABJ-2-based designs.
