Product details
Overview
DG418DJ-E3 from Vishay Siliconix is a precision CMOS single-pole, single-throw (SPST), normally-open analog switch designed for bidirectional signal routing in low-power, high-accuracy systems. It delivers 20 Ω on-resistance, 100 ns turn-on time, ±15 V analog signal range, and 35 nW ultra-low power dissipation - enabling use in battery-powered instrumentation and portable test equipment.
For engineers reviewing the DG418DJ-E3 datasheet, DG418DJ-E3 pinout, DG418DJ-E3 application, or DG418DJ-E3 equivalent, key selection criteria include its dual-supply operation (±5 V to ±20 V), break-before-make compatibility with DG419 in system-level SPDT designs, TTL/CMOS logic interface, MiniDIP-8 package footprint, and guaranteed leakage <0.25 nA at full temperature range.
Technical Context
The DG418DJ-E3 implements a high-voltage silicon gate (HVSG) process to achieve robust ±44 V supply rating and latchup immunity via epitaxial isolation. Its complementary control logic (active-high enable) directly opposes DG417, allowing matched pair usage in differential or redundant switching paths.
It operates with symmetrical conduction in both directions when on, blocks signals up to rail voltage when off, and maintains stable RDS(on) across ±12.5 V analog swing - critical for precision DC-coupled signal chains in medical sensors and automated test equipment.
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 typical - ensures minimal gain error and THD degradation in 1 kΩ–10 kΩ load interfaces |
| Turn-on time (ton) | 100 ns - enables sub-microsecond channel selection in multiplexed data acquisition systems |
| Supply voltage max | 44 V - accommodates wide industrial supply rails and transient-tolerant designs |
| Switch leakage (IS(off)) | ±0.25 nA max at full temp - preserves nanoamp-level accuracy in electrometer-grade circuits |
| Power dissipation | 35 nW - allows continuous operation in energy-constrained IoT sensor nodes and wearable devices |
| Logic compatibility | TTL and CMOS - simplifies direct interfacing with microcontrollers and FPGAs without level-shifting |
Pinout & Package
Package: 8-pin plastic MiniDIP (DIP-8), JEDEC MS-001, body width 7.62 mm, lead pitch 2.54 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Source terminal | Bidirectional analog signal path input/output; connects to signal source or load depending on configuration |
| 2 (D) | Drain terminal | Bidirectional analog signal path input/output; complements S pin for SPST switching path |
| 3 (NC) | No-connect | Internally unconnected; must remain floating - no PCB trace or pull-up/down allowed |
| 4 (V−) | Negative supply rail | Bias reference for negative analog swing; requires local decoupling near pin |
| 5 (GND) | Ground reference | Logic and substrate reference; separate from analog ground in mixed-signal layouts |
| 6 (IN) | Digital control input | Active-high logic enable (≥2.4 V = ON); compatible with 3.3 V/5 V microcontroller GPIO |
| 7 (V+) | Positive supply rail | Bias reference for positive analog swing; supports up to +44 V for overvoltage resilience |
| 8 (VL) | Logic supply voltage | Independent 5 V logic rail; isolates digital switching noise from analog signal path |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make compatible control | Shares identical timing envelope and logic thresholds with DG419, enabling seamless integration into SPDT systems using two DG418 units |
| Ultra-low charge injection (60 pC) | Minimizes voltage glitch on sample-and-hold capacitors, preserving <12-bit settling accuracy in ADC front-ends |
| Epitaxial latchup protection | Guarantees immunity to destructive latchup under transient overvoltage or ESD events per JEDEC JESD78 |
| High off-isolation (>60 dB) | Ensures >1 MΩ effective channel resistance at 1 MHz, critical for crosstalk-sensitive multi-channel multiplexers |
| MiniDIP-8 RoHS-compliant packaging | Lead-free terminations (E3 suffix), compatible with standard through-hole reflow and wave soldering processes |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESA+ | Higher RDS(on) (35 Ω), slower ton (150 ns), single 5 V logic supply only | Less suitable for ±15 V bipolar signal routing; better for 3.3 V embedded systems | Select when board space favors SO-8 and supply is strictly 5 V; avoid for precision DC-coupled paths |
| ADG1419BRUZ | SPDT configuration, 1.8 Ω RDS(on), 12 V max dual supply, higher cost | Direct SPDT replacement but not pin-compatible; requires PCB redesign | Choose for ultra-low on-resistance needs in new designs; not drop-in for DG418DJ-E3 sockets |
Compared with MAX4617ESA+ and ADG1419BRUZ, the DG418DJ-E3 uniquely balances ±15 V analog range, 20 Ω on-resistance, and MiniDIP-8 through-hole reliability - making it optimal for field-serviceable test gear and legacy industrial controllers where socket replacement and thermal cycling endurance are critical.

FAQ
What is the maximum supply voltage rating for DG418DJ-E3?
The DG418DJ-E3 has an absolute maximum supply voltage rating of 44 V across V+ and V− terminals. This allows safe operation with ±22 V dual supplies or 0–44 V single-ended configurations. Operation beyond this limit risks permanent damage, and derating is required above 25 °C per the datasheet's 6 mW/°C thermal specification.
Does DG418DJ-E3 support single-supply operation?
Yes, DG418DJ-E3 supports single-supply operation from 5 V to 40 V. When used with V− tied to GND, it handles 0–12 V analog signals (unipolar mode). The VL pin must still be supplied with 5 V for logic compatibility, and the device maintains 40 Ω typical RDS(on) and 110 ns ton under these conditions per the unipolar specifications table.
How does DG418DJ-E3 differ from DG417DJ-E3 in control logic?
DG418DJ-E3 uses active-high logic (IN ≥ 2.4 V = ON), whereas DG417DJ-E3 uses active-low logic (IN ≤ 0.8 V = ON). This complementary behavior enables matched-pair usage - for example, driving both with the same microcontroller output via an inverter to create redundant or differential switching paths without additional logic gates.
Is DG418DJ-E3 RoHS-compliant?
Yes, the "-E3" suffix denotes lead-free, RoHS-compliant terminations per EU Directive 2011/65/EU. The MiniDIP-8 package uses matte tin plating over copper leads, qualified for standard SnPb and Pb-free soldering processes. Full compliance documentation, including substance declarations and test reports, is available upon request from Aetrix Electronics.
What is the guaranteed leakage current specification for DG418DJ-E3 over temperature?
DG418DJ-E3 guarantees switch-off leakage current (IS(off)) of ±0.25 nA maximum over the full −40 °C to +85 °C operating range. At room temperature, typical leakage is ±0.1 nA. This performance is enabled by the HVSG process and epitaxial isolation layer, ensuring stability in high-impedance sensor interfaces and electrometer circuits.
