Product details
Overview
DG417DK from Maxim Integrated is a precision, normally closed (NC), single-pole/single-throw (SPST) analog switch optimized for rail-to-rail signal routing in high-fidelity sample-and-hold and test equipment circuits. It features 35Ω max on-resistance, <5nA off-leakage at +85°C, 10pC max charge injection, 175ns max turn-on time, and operates from ±4.5V to ±20V or +10V to +30V supplies.
For engineers reviewing the DG417DK datasheet, DG417DK pinout, DG417DK application, or DG417DK equivalent, this device is selected for low-distortion analog switching where guaranteed on-resistance matching (3Ω max), flat on-resistance over signal range (4Ω max), and ESD tolerance (2000V min) are critical in military radios, guidance systems, and battery-operated instrumentation.
Technical Context
The DG417DK uses a 44V silicon-gate CMOS process to achieve rail-to-rail analog signal handling and TTL/CMOS logic compatibility. Its normally closed architecture ensures continuity during power loss or logic reset, supporting fail-safe signal paths in PBX and control systems.
Guaranteed on-resistance flatness (4Ω max) and channel-to-channel matching (3Ω max) are specified only under bipolar supply operation (±4.5V to ±20V), enabling precise gain-setting and matched attenuation in dual-channel instrumentation front-ends without calibration.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Normally closed (NC) SPST - maintains signal path when control input is low or unpowered. |
| RDS(ON) | 35Ω max at +25°C - enables low insertion loss in audio and DC-coupled sensor interfaces. |
| Charge Injection | 10pC max - minimizes voltage glitch in sample-and-hold circuits with ≤10nF hold capacitors. |
| tON/tOFF | 175ns / 145ns max - supports multiplexing at >1MHz sampling rates in automated test equipment. |
| Off-Leakage (IS(OFF)) | <5nA at +85°C - preserves accuracy in high-impedance sensor front-ends and long-interval integrators. |
| Supply Range | ±4.5V to ±20V (bipolar) or +10V to +30V (single) - accommodates industrial ±15V and battery-powered +12V systems. |
| ESD Tolerance | 2000V min per Method 3015.7 - reduces handling damage risk in assembly and field maintenance. |
Pinout & Package
Package: 8-pin CERDIP (Ceramic Dual In-line Package), hermetically sealed, rated for -55°C to +125°C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Analog Source (S) | Normally closed switch terminal - connects to load or signal path when IN = low. |
| 2 | No Internal Connection (N.C.) | Unbonded pad - must be left floating; no electrical function or thermal tie. |
| 3 | GND | Logic ground reference - separate from analog V−; requires low-impedance local decoupling. |
| 4 | V+ | Analog positive supply - sets upper rail of signal range; must be ≥|V−| + 9V for full ±20V operation. |
| 5 | VL | Logic supply input - tied to +5V for TTL compatibility or to V+ for CMOS-level inputs. |
| 6 | IN | Active-low logic control - drives switch open (high-Z) when logic high (≥2.4V). |
| 7 | V− | Analog negative supply - defines lower signal rail; must be ≤V+ − 9V for full ±20V operation. |
| 8 | D | Analog Drain - common terminal connected to source (S) when switch is closed (IN = low). |
Key Features
| Feature | Design Value |
|---|---|
| Guaranteed RDS(ON) match | 3Ω max between channels - ensures matched gain/attenuation in dual-path instrumentation. |
| Rail-to-rail signal handling | Full analog swing from V− to V+ - eliminates level-shifting in ±15V op-amp signal chains. |
| Low charge injection | 10pC max - limits hold-step error to <1mV in 10-bit 10nF sample-and-hold designs. |
| Bipolar & single-supply support | Operates from ±4.5V to ±20V or +10V to +30V - simplifies power architecture across test and military platforms. |
| High-temperature leakage performance | <5nA off-leakage at +85°C - maintains >12-bit integrity over industrial temperature range. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | SPDT configuration, 1.5Ω typical RDS(ON), but only rated to +125°C (not -55°C); no guaranteed RFLAT(ON). | Requires redesign for SPDT vs. NC-SPST topology; unsuitable for fail-safe continuity requirements. | Select only if SPDT functionality and lower on-resistance outweigh need for extended cold-temperature operation and flatness guarantee. |
| TS5A3157DCKR | Single-supply only (+1.65V to +5.5V), 0.75Ω RDS(ON), but 100nA off-leakage at +85°C and no ESD rating above 2kV. | Limited to low-voltage portable audio; cannot replace DG417DK in ±15V industrial or military signal chains. | Use only in battery-powered consumer devices where rail-to-rail ±20V operation and sub-5nA leakage are not required. |
Compared with ADG1419BRUZ and TS5A3157DCKR, the DG417DK uniquely delivers guaranteed on-resistance flatness, -55°C capability, and fail-safe NC operation in a hermetic CERDIP package-making it irreplaceable in high-reliability analog routing where signal fidelity and environmental robustness are non-negotiable.

FAQ
What is the operating temperature range of the DG417DK?
The DG417DK is specified for -55°C to +125°C operation, validated per MIL-STD-883B environmental stress screening. This extended range supports deployment in aerospace guidance systems and downhole oilfield instrumentation where commercial or industrial grade switches would fail. The DG417DK maintains guaranteed on-resistance flatness and sub-5nA off-leakage across this full span, unlike standard plastic-packaged variants.
Is the DG417DK pin-compatible with older DG417 variants like DG417DJ?
Yes, the DG417DK shares identical 8-pin CERDIP pinout and logic interface with all DG417 family members, including DG417DJ and DG417AK. All share the same S/D/IN/V+/V−/VL/GND/N.C. assignment and NC-SPST functionality. However, the DG417DK adds improved on-resistance matching (3Ω max) and tighter charge injection (10pC max) versus earlier revisions.
Can the DG417DK operate from a single +12V supply?
Yes, the DG417DK supports single-supply operation from +10V to +30V by connecting V− to ground. In this mode, the analog signal range is 0V to +12V, and on-resistance rises slightly versus bipolar operation. Key specs like leakage and switching speed remain valid, but guaranteed RFLAT(ON) and RDS(ON) match apply only under bipolar supply conditions per the datasheet.
What does "normally closed" mean for the DG417DK?
"Normally closed" means the internal switch conducts between drain (D) and source (S) terminals when the IN pin is logic low (≤0.8V) or unpowered. When IN is driven high (≥2.4V), the switch opens. This fail-safe behavior ensures signal continuity during power loss or controller reset-critical in guidance system sensor paths and emergency radio receive chains where uninterrupted signal flow is mandatory.
Does the DG417DK require external protection diodes for overvoltage?
No, external diodes are optional. The DG417DK includes internal ESD protection rated to 2000V per Method 3015.7. However, for systems subject to supply transients exceeding absolute maximum ratings (e.g., V+ > 44V), Maxim recommends adding series diodes on V+ and V− pins-as shown in Figure 1 of the DG417DK datasheet-to clamp overvoltage without degrading on-resistance or leakage performance.
