Product details
Overview
DG211DJ+ from Maxim Integrated is a quad SPST normally closed analog switch designed for bidirectional signal routing in ±4.5V to ±18V dual-supply systems. It features 175Ω max RDS(ON), 1000ns max turn-on time, 500ns max turn-off time, and guaranteed break-before-make switching. Used in military radios and test equipment where supply disconnection with live inputs must not cause latch-up.
For engineers reviewing the DG211DJ+ datasheet, DG211DJ+ pinout, DG211DJ+ application, or DG211DJ+ equivalent, key selection criteria include analog signal range (±15V), leakage performance (±5nA off-leakage), power supply independence (no VL rail required), and DIP-16 package compatibility with legacy industrial layouts.
Technical Context
The DG211DJ+ implements monolithic CMOS SPST switches with nonlatching behavior during supply removal-ensuring safe operation when input signals remain active while V+ or V− is disconnected. Its logic inputs are TTL/CMOS compatible, eliminating level-shifting circuitry.
Each of the four independent channels supports bidirectional analog signals up to ±15V with guaranteed break-before-make timing, preventing momentary short-circuits during channel switching. The device operates without a third VL supply, simplifying system power architecture versus legacy equivalents.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15V - Supports full-rail signal switching across industrial and military voltage ranges. |
| RDS(ON) Max | 175Ω at ±10V - Ensures low insertion loss and minimal signal distortion in precision analog paths. |
| Turn-On Time Max | 1000ns - Enables reliable switching in moderate-speed instrumentation and control loops. |
| Turn-Off Time Max | 500ns - Guarantees fast channel isolation critical in multiplexed data acquisition systems. |
| Off-Leakage Current | ±5nA at ±14V - Maintains high-impedance signal integrity in high-gain or low-current sensor interfaces. |
| Supply Range | ±4.5V to ±18V - Allows flexible integration into existing ±5V, ±12V, or ±15V systems without regulation. |
| No VL Supply Required | True - Eliminates dedicated logic supply rail, reducing BOM count and PCB routing complexity. |
Pinout & Package
Package: 16-pin plastic DIP (0.300" wide), RoHS-compliant, through-hole mountable with standard 0.1" pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 8, 9, 16 | IN1–IN4 | Logic control inputs; active-high enables corresponding switch channel (normally closed). |
| 2, 7, 10, 15 | D1–D4 | Drain terminals; connect to analog signal sources or loads in bidirectional configuration. |
| 3, 6, 11, 14 | S1–S4 | Source terminals; routed to common analog bus or measurement point per channel. |
| 4 | V− | Negative supply rail input; substrate connection for internal CMOS structure. |
| 5 | GND | Signal reference ground; separate from power ground in mixed-signal designs. |
| 12 | N.C. | No internal connection; must be left unconnected or tied to GND per layout best practice. |
| 13 | V+ | Positive supply rail input; also connected to substrate for latch-up immunity. |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed break-before-make | Prevents transient shorts during channel switching-critical for protecting downstream ADCs or amplifiers. |

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), but only ±5V supply range; requires VL rail. | Better for low-voltage portable instruments; unsuitable for ±15V industrial/military rails. | Select MAX4617CSE+ only if system operates strictly at 5V and needs lower on-resistance. |
| ADG1412BRUZ | Higher supply range (±22V), 1.8Ω RDS(ON), but 20-pin TSSOP; no DIP option. | Superior performance in high-precision medical or aerospace systems; incompatible with legacy DIP footprints. | Choose ADG1412BRUZ when upgrading for performance and board space allows re-layout. |
Compared with MAX4617CSE+ and ADG1412BRUZ, the DG211DJ+ uniquely balances ±18V operation, DIP-16 legacy compatibility, and no-VL simplicity-making it the only drop-in replacement for fielded DG211-based systems requiring long-term obsolescence resilience.

FAQ
What is the operating temperature range for DG211DJ+?
The DG211DJ+ is rated for −40°C to +85°C operation, matching the DG211D/E grade specification. This extended range supports deployment in military radios, avionics subsystems, and industrial control cabinets where ambient temperatures exceed commercial limits. All electrical parameters-including RDS(ON), leakage, and switching times-are guaranteed across this full range per the datasheet's "DG211D/E" column.
Does DG211DJ+ require a VL logic supply voltage?
No, DG211DJ+ does not require a VL supply. Unlike earlier analog switch generations, Maxim eliminated the third rail-logic inputs operate directly from V+ and V−, accepting standard CMOS/TTL levels (0V to V+). This simplifies power design and reduces component count. The DG211DJ+ datasheet explicitly states "No VL Supply Required" as a key feature, confirmed in both absolute maximum ratings and functional descriptions.
Is DG211DJ+ pin-compatible with the original DG211 from the prior manufacturer?
Yes, DG211DJ+ maintains identical pinout, package (16-pin plastic DIP), and electrical behavior as the original DG211, including the same IN/D/S terminal assignments and V+/V−/GND locations. Maxim designed it as a direct functional and mechanical replacement, with improved specs (lower power, no VL rail) and enhanced latch-up immunity-verified in the Pin Configurations and Ordering Information tables.
What is the maximum analog signal voltage supported by DG211DJ+?
DG211DJ+ supports analog signals from −15V to +15V, as specified in the VANALOG parameter (±15V) under Electrical Characteristics. This rating holds across the full operating temperature range and is validated for continuous operation with ±15V supplies. Signals beyond ±15V risk exceeding absolute maximum ratings and may damage the device or degrade long-term reliability.
How does DG211DJ+ prevent latch-up when power supplies are disconnected?
DG211DJ+ prevents latch-up via internal design that isolates substrate bias during supply removal. When V+ or V− is disconnected while analog inputs remain active, internal protection structures ensure source-to-body diodes do not forward-bias uncontrollably. This nonlatching behavior is guaranteed per the datasheet and tested per JEDEC JESD78, making DG211DJ+ suitable for hot-swap and power-fail scenarios in guidance and control systems.
