Product details
Overview
DG417DJ from Vishay Siliconix is a precision monolithic CMOS single-pole, normally-closed (SPST-NC) analog switch optimized for high-fidelity signal routing in low-power, dual-supply systems. It delivers 20 Ω on-resistance, ±15 V analog signal range, 100 ns turn-on time, and ultra-low 35 nW power dissipation - enabling use in battery-powered instrumentation and portable test equipment where leakage, distortion, and board space are critical.
For engineers reviewing the DG417DJ datasheet, DG417DJ pinout, DG417DJ application, or DG417DJ equivalent, key selection criteria include its SPST-NC configuration, guaranteed break-before-make compatibility with DG419 in system-level switching designs, TTL/CMOS logic interface, and MiniDIP-8 packaging for through-hole prototyping and rugged industrial deployment.
Technical Context
The DG417DJ implements a high-voltage silicon gate (HVSG) process to achieve 44 V absolute maximum supply rating and latchup immunity via epitaxial isolation. Its complementary control logic (active-low enable) distinguishes it from DG418 (active-high), enabling direct interfacing with microcontroller GPIOs without level-shifting.
Each channel conducts bidirectionally with matched on-resistance across the full ±15 V analog range and blocks signals up to the supply rails when off. Charge injection is specified at 60 pC, supporting precision sample-and-hold and multiplexed ADC front-ends where signal integrity must be preserved across switching transitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog signal range | ±15 V - supports rail-to-rail bipolar signal switching without clipping in dual-supply precision circuits |
| On-resistance (RDS(on)) | 20 Ω typical - ensures minimal gain error and THD degradation in audio and instrumentation amplifier paths |
| Turn-on time (ton) | 100 ns - enables sub-microsecond channel selection in high-speed data acquisition systems |
| Supply voltage max | 44 V - allows operation with overvoltage-tolerant industrial supplies and margin against transients |
| Power dissipation | 35 nW - reduces thermal drift and extends battery life in portable medical and field-test devices |
| Switch off leakage | ±0.25 nA max at full temperature range - preserves accuracy in high-impedance sensor interfaces and integrator circuits |
| Logic compatibility | TTL and CMOS - simplifies direct connection to FPGA I/O banks and microcontroller outputs without external drivers |
Pinout & Package
Package: 8-pin plastic MiniDIP (DIP-8), 0.300" wide body per JEDEC MS-001, with lead spacing of 0.100" (2.54 mm) and standard through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Source terminal | Bidirectional analog input/output node; connects to signal source or load depending on switch state |
| 2 (D) | Drain terminal | Bidirectional analog input/output node; forms switched path with S when enabled |
| 3 (NC) | No-connect | Internally unconnected pin; must remain floating - no PCB trace or component attachment |
| 4 (V−) | Negative supply rail | Reference for negative analog swing; must be decoupled locally to minimize noise coupling |
| 5 (GND) | Digital ground | Logic reference return; isolated from analog ground in mixed-signal layouts to prevent digital noise injection |
| 6 (IN) | Control input | Active-low digital enable; logic "0" ≤ 0.8 V turns switch ON; logic "1" ≥ 2.4 V turns OFF |
| 7 (V+) | Positive supply rail | Reference for positive analog swing; supports up to +44 V for transient robustness |
| 8 (VL) | Logic supply | Independent 5 V logic rail; decouples digital switching noise from analog supply domains |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage silicon gate (HVSG) process | Enables 44 V supply rating and latchup immunity - critical for industrial environments with supply transients |
| Bidirectional conduction | Equal on-resistance in both directions eliminates polarity-dependent gain errors in AC-coupled signal chains |
| Ultra-low leakage (≤0.25 nA) | Maintains DC accuracy in high-impedance applications such as pH sensors and piezoelectric transducer interfaces |
| MiniDIP-8 package | Supports manual soldering, socket-based testing, and legacy PCB footprints - ideal for lab validation and low-volume production |
| Break-before-make compatible timing | Guaranteed non-overlapping switching with DG419 in multi-channel SPDT systems - prevents momentary shorts during reconfiguration |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1419BRUZ | SPDT configuration, 1.8 Ω RDS(on), 5 V single-supply only, 125 ns ton | Optimized for low-RDS(on) in 5 V data acquisition; lacks dual-supply flexibility and ±15 V range | Select when lowest on-resistance is prioritized over bipolar signal support and wide supply range |
| MAX4617ESA+ | SPST-NO, 60 Ω RDS(on), ±15 V range, 150 ns ton, SO-8 only | Higher on-resistance limits use in precision gain-setting paths but offers same voltage range and temperature grade | Select when NO configuration is required and MiniDIP footprint is not mandatory |
Compared with DG417DJ, ADG1419BRUZ provides lower on-resistance but sacrifices dual-supply operation and MiniDIP packaging; MAX4617ESA+ matches voltage range and temperature rating but requires redesign for NO logic and higher RDS(on) tolerance.

FAQ
What is the maximum analog signal voltage supported by the DG417DJ?
The DG417DJ supports an analog signal range of ±15 V when operated with dual supplies (V+ = +15 V, V− = −15 V). Its absolute maximum supply rating is 44 V, but the guaranteed linear analog range remains ±15 V under standard operating conditions. This makes DG417DJ suitable for precision bipolar signal routing in test and measurement gear without external clamping or level-shifting circuitry.
Does the DG417DJ require a separate logic supply voltage?
Yes, the DG417DJ requires a dedicated logic supply (VL) pin, typically connected to +5 V. This separates digital switching noise from analog supply domains (V+, V−), reducing crosstalk and preserving signal integrity. The VL pin accepts 4.5 V to 5.5 V and must be decoupled with a 0.1 µF ceramic capacitor near the package - a design requirement explicitly defined in the DG417DJ datasheet for stable logic-level recognition.
Is the DG417DJ pin-compatible with the DG418DJ or DG419DJ?
No, the DG417DJ is not pin-compatible with DG418DJ or DG419DJ. While all three share the same MiniDIP-8 package outline, their internal configurations differ: DG417DJ is SPST-NC, DG418DJ is SPST-NO, and DG419DJ is SPDT. Pin 3 is NC on DG417DJ/DG418DJ but connects to S2 on DG419DJ. Swapping them without board revision will cause functional failure or signal shorting.
What is the typical on-resistance temperature coefficient of the DG417DJ?
The DG417DJ exhibits a typical on-resistance temperature coefficient of approximately +3500 ppm/°C, derived from RDS(on) vs. temperature curves in the datasheet. At −40 °C, RDS(on) is ~16 Ω; at +85 °C, it rises to ~28 Ω. This variation must be accounted for in precision gain-setting or calibration-critical paths - the DG417DJ datasheet does not specify guaranteed TC, only min/max RDS(on) across temperature.
Can the DG417DJ operate from a single 12 V supply?
Yes, the DG417DJ supports single-supply operation with V+ = 12 V and V− = 0 V, delivering a 0 V to 12 V analog signal range. In this mode, RDS(on) increases to 40 Ω (typical), turn-on time becomes 110 ns, and leakage remains within spec. The logic supply (VL) must still be 5 V, and the control input thresholds (0.8 V low / 2.4 V high) remain unchanged - enabling seamless integration into 3.3 V or 5 V microcontroller systems.
