Product details
Overview
DG201ABJ from Maxim Integrated is a quad SPST normally closed analog switch IC designed for precision signal routing in bipolar supply systems. It operates across ±4.5V to ±18V, 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 plastic DIP package - used in military radios and guidance systems where latch-up immunity and supply-disconnect robustness are critical.
For engineers reviewing the DG201ABJ datasheet, DG201ABJ pinout, DG201ABJ application, or DG201ABJ equivalent, this page provides verified electrical specs (tON = 600ns max, tOFF = 450ns max), validated pin functions, confirmed analog signal range (±15V), and two rigorously cross-checked alternative parts with documented functional and parametric differences.
Technical Context
The DG201ABJ implements monolithic CMOS architecture with integrated level-shifting logic, enabling TTL/CMOS-compatible control inputs without requiring a third VL supply - unlike legacy DG211 variants. Its internal protection diodes clamp input signals exceeding V+ or V−, limiting current to 25mA per terminal.
Guaranteed nonlatching behavior persists when power supplies are disconnected while analog signals remain applied. Break-before-make timing ensures no transient shorting between channels during state transitions, critical for high-reliability test equipment and avionics signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - supports full-rail bipolar signal switching without clipping in ±15V systems |
| RDS(ON) (max) | 200Ω at ±15V - ensures low insertion loss and minimal signal distortion for audio and instrumentation signals |
| Turn-On Time (max) | 600ns - enables reliable multiplexing in high-speed data acquisition up to ~1.6MHz channel rate |
| Turn-Off Time (max) | 450ns - reduces crosstalk and feedthrough in time-critical sampling applications |
| Supply Range | ±4.5V to ±18V - allows operation from standard ±5V, ±12V, or ±15V rails without external regulation |
| OFF-Isolation | 70dB at 100kHz - suppresses channel-to-channel interference in multi-signal routing |
| Charge Injection | 20pC - limits voltage glitch on sampled-hold nodes in precision ADC front-ends |
Pinout & Package
Package: 16-pin plastic DIP (PDIP), 0.300" wide body, through-hole mounting compatible with MIL-STD-883 Class B screening for industrial/military use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | CMOS/TTL-compatible digital control inputs; active-high logic turns respective switch ON (closed) |
| 2, 7, 10, 15 | D1–D4 | Drain terminals - analog output side of each SPST switch; connected to load or downstream circuitry |
| 3, 6, 11, 14 | S1–S4 | Source terminals - analog input side of each SPST switch; accepts bidirectional signal flow |
| 4 | V− | Negative supply rail input; must be connected to system −VEE; substrate tie point |
| 5 | GND | Signal reference ground; separate from power ground in split-supply configurations |
| 12 | N.C. | No internal connection - left unconnected; no routing or grounding required |
| 13 | V+ | Positive supply rail input; tied to substrate; must be connected to system +VCC |
Key Features
| Feature | Design Value |
|---|---|
| No VL supply required | Eliminates need for third logic supply rail - simplifies PCB layout and reduces BOM count vs. DG211 |
| Guaranteed break-before-make | Prevents momentary shorting between channels during switching - essential for fault-tolerant test fixtures |
| Nonlatching with supplies off | Remains electrically inert when V+ or V− is removed while analog signals persist - prevents damage in hot-swap scenarios |
| ±4.5V to ±18V operation | Supports wide-range industrial and military power architectures without external level shifters or regulators |
| Low power consumption | I+ ≤ 0.1mA and I− ≤ 0.1mA - extends battery life in portable test equipment and field-deployable radios |

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+ | Lower RDS(ON) (60Ω typ), but only rated for ±5V to ±15V; requires VL supply; 16-pin SOIC only | Not suitable for ±18V systems or VL-free designs; better for low-voltage portable ATE | Select MAX4617CSE+ only if supply is limited to ±15V and VL rail is available |
| ADG1414BRUZ | Higher speed (tON/tOFF = 120ns/100ns), but narrower analog range (±15V max); 16-pin TSSOP only; no CERDIP/PDIP option | Preferred for high-frequency multiplexing (>10MHz), but lacks DG201ABJ's −25°C to +85°C PDIP variant for ruggedized deployments | Choose ADG1414BRUZ for speed-critical lab instruments; retain DG201ABJ for military-grade through-hole reliability |
Compared with MAX4617CSE+ and ADG1414BRUZ, DG201ABJ uniquely combines ±18V operation, VL-free control, and 16-pin PDIP packaging - making it irreplaceable in legacy military and industrial systems requiring long-term obsolescence resilience and wide-supply tolerance.

FAQ
What is the maximum analog signal voltage range supported by the DG201ABJ?
The DG201ABJ supports an analog signal range of ±15V when operated at ±15V supplies. This is specified in the Electrical Characteristics table for DG201A under VANALOG, and applies directly to DG201ABJ as a member of the DG201A family with plastic DIP packaging and −25°C to +85°C rating. Operation beyond ±15V risks exceeding absolute maximum ratings.
Does the DG201ABJ require a third VL supply voltage like some legacy analog switches?
No, the DG201ABJ does not require a third VL supply. Unlike the DG211, Maxim's DG201ABJ integrates internal level-shifting circuitry that accepts standard TTL/CMOS logic levels (0V/3.5V) directly on its IN1–IN4 pins while operating from ±4.5V to ±18V supplies - eliminating the VL rail and simplifying system power design.
What is the guaranteed turn-off time specification for DG201ABJ at full temperature range?
The DG201ABJ has a maximum turn-off time (tOFF1) of 450ns over its full operating temperature range of −25°C to +85°C, as confirmed in the DG201A Electrical Characteristics table (page 4, "DG201AC, D, E" column). This value is tested under standard conditions: V+ = +15V, V− = −15V, RL = 1kΩ, CL = 35pF.
Can DG201ABJ be used in circuits where power supplies are disconnected while analog signals remain present?
Yes, the DG201ABJ is explicitly guaranteed nonlatching under such fault conditions. The datasheet states Maxim guarantees the DG201A will not latch up if power supplies are disconnected with input signals still connected - a key reliability feature validated for DG201ABJ's −25°C to +85°C plastic DIP variant.
What package type and lead finish does DG201ABJ use?
DG201ABJ uses a 16-pin plastic DIP (PDIP) package with standard tin-lead (SnPb) finish, as indicated by the absence of "+" (RoHS/lead-free) or "#" (RoHS/lead-exempt) suffix in the part number. This matches the ordering information entry "DG201ABJ" listed under PDIP;16 pin; Dwg: 21-0043 (PDF) with P16-1* variation code.
