Product details
Overview
DG417DJ-E3 from Vishay Siliconix is a precision monolithic CMOS single-pole, normally-closed (SPST-NC) analog switch designed for high-fidelity signal routing in low-power, high-precision 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.
For engineers reviewing the DG417DJ-E3 datasheet, DG417DJ-E3 pinout, DG417DJ-E3 application, or DG417DJ-E3 equivalent, key selection criteria include its SPST-NC configuration, HVSG process-based latchup immunity, guaranteed break-before-make compatibility with DG419 in system-level switching designs, and MiniDIP-8 packaging for through-hole prototyping and industrial control interfaces.
Technical Context
The DG417DJ-E3 implements a single-channel analog switch using Vishay's high-voltage silicon gate (HVSG) process, enabling operation across ±15 V dual supplies or 5–40 V single supplies. Its CMOS architecture ensures symmetrical bidirectional conduction when on and blocking up to supply rails when off, with TTL/CMOS-compatible digital control logic.
Break-before-make timing is not guaranteed for DG417DJ-E3 (unlike DG419), and it features opposite control logic to DG418: logic low (≤0.8 V) enables conduction, while logic high (≥2.4 V) disables the switch. An epitaxial layer prevents latchup, and internal clamping diodes protect against overvoltage transients on S/D/IN pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail bipolar signal switching without clipping in precision instrumentation front-ends |
| On-Resistance (RDS(on)) | 20 Ω typ. - minimizes voltage drop and gain error in low-impedance signal paths (e.g., sensor multiplexing) |
| Turn-On Time (ton) | 100 ns typ. - enables sub-microsecond channel selection in automated test equipment scan cycles |
| Supply Voltage Range | ±15 V dual or 5–40 V single - allows flexible integration into legacy ±15 V op-amp systems or modern 12/24 V industrial rails |
| Power Dissipation | 35 nW typ. - permits deployment in always-on, micropower applications such as memory backup switches and UPS transfer circuits |
| Switch Leakage (IS(off)) | ±0.25 nA max. at full temperature - preserves accuracy in high-impedance sample-and-hold and integrator circuits |
| Charge Injection | 60 pC - limits voltage glitch on capacitive loads (e.g., ADC input hold capacitors), critical for 14+ bit resolution systems |
Pinout & Package
DG417DJ-E3 is housed in an 8-pin plastic MiniDIP package (JEDEC MS-001), with 0.3-inch body width, 0.1-inch lead pitch, and through-hole mounting. Pin 1 is marked by a notch or dot; leads are tin-lead (Pb) terminated per ordering suffix -E3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Source Terminal | Analog input/output node; bidirectional conduction path when switch is enabled |
| 2 (D) | Drain Terminal | Analog output/input node; electrically interchangeable with S in on-state |
| 3 (NC) | No-Connect | Internally unconnected; must remain floating or grounded per layout best practice |
| 4 (V−) | Negative Supply Rail | Bias reference for negative analog swing; must be decoupled locally to minimize noise coupling |
| 5 (GND) | Digital Ground | Logic return path; isolated from analog ground in mixed-signal designs to prevent digital noise injection |
| 6 (IN) | Digital Control Input | Active-low enable: ≤0.8 V turns switch ON; ≥2.4 V turns switch OFF |
| 7 (V+) | Positive Supply Rail | Bias reference for positive analog swing; supports up to +44 V absolute max rating |
| 8 (VL) | Logic Supply Reference | Defines logic threshold voltage; tied to +5 V for TTL/CMOS compatibility or to V+ for single-supply operation |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Silicon Gate (HVSG) Process | Enables 44 V absolute max supply rating and superior leakage performance vs. standard CMOS processes |
| Epitaxial Latchup Protection | Guarantees immunity to destructive latchup under transient overvoltage or ESD stress conditions |
| Bidirectional Analog Conduction | Eliminates signal polarity constraints-supports AC-coupled, differential, or rail-to-rail analog signals |
| TTL/CMOS Logic Compatibility | Accepts standard 0 V / 5 V logic levels without level-shifting, simplifying interface with microcontrollers and FPGAs |
| MiniDIP-8 Through-Hole Package | Supports manual assembly, rework, and long-term reliability in industrial environments with thermal cycling |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617CPA+ | SPST-NC, 35 Ω RDS(on), 125 ns ton, SO-8 only; no MiniDIP option | Higher on-resistance increases gain error in precision gain-setting networks | Select when SO-8 surface-mount is preferred and 15 Ω higher RDS(on) is acceptable |
| ADG1419BRUZ | SPDT, 1.8 Ω RDS(on), 170 ns ton, ±15 V rated, TSSOP-16 | SPDT topology requires redesign for SPST-NC function; lower RDS(on) improves low-level signal fidelity | Choose for ultra-low on-resistance needs where board space allows TSSOP-16 and SPDT functionality is usable |
Compared with MAX4617CPA+ and ADG1419BRUZ, DG417DJ-E3 offers the lowest combination of on-resistance (20 Ω), charge injection (60 pC), and power consumption (35 nW) in a through-hole MiniDIP package-making it optimal for legacy-compatible, high-accuracy, low-power analog routing where manual assembly or thermal robustness is required.

FAQ
What is the maximum supply voltage rating for DG417DJ-E3?
DG417DJ-E3 has an absolute maximum supply rating of +44 V on V+ and –44 V on V−, with a maximum differential voltage of 44 V between V+ and V−. Operation beyond these limits risks permanent damage. For reliable long-term use, the recommended dual-supply range is ±15 V, and the single-supply range is 5–40 V, as specified in the datasheet.
Does DG417DJ-E3 support single-supply operation?
Yes, DG417DJ-E3 supports single-supply operation from 5 V to 40 V. In this mode, V− is connected to ground, V+ receives the positive rail, and VL is tied to the same voltage as V+ or to a separate 5 V logic supply. The analog signal range becomes 0 V to V+, enabling use in 12 V or 24 V industrial systems without dual-rail generation.
What is the logic polarity of the IN pin on DG417DJ-E3?
The IN pin on DG417DJ-E3 is active-low: a logic low (≤0.8 V) turns the switch ON (conducting between S and D), and a logic high (≥2.4 V) turns it OFF (open circuit). This is the inverse of DG418, which uses active-high control. Proper logic level alignment is essential to avoid unintended switching behavior.
Is DG417DJ-E3 pin-compatible with DG419DJ-E3?
No, DG417DJ-E3 is not pin-compatible with DG419DJ-E3. Although both use MiniDIP-8 packages, their pinouts differ: DG417DJ-E3 has S, D, NC, V−, GND, IN, V+, VL; DG419DJ-E3 has D, S2, S1, V−, GND, IN, V+, VL. Swapping them without PCB revision will result in incorrect signal routing and potential damage due to misconnected terminals.
What is the purpose of the VL pin on DG417DJ-E3?
The VL pin sets the logic threshold reference voltage for the IN control input. When VL = 5 V, the device interprets 0–0.8 V as logic low and 2.4–5 V as logic high. When VL is tied to V+, the logic thresholds scale with the supply-enabling direct interfacing with microcontrollers operating at the same rail. Leaving VL unconnected is not permitted and may cause undefined switching behavior.
