Product details
Overview
DG417DY-T1 from Vishay Siliconix is a precision single-pole, normally-closed (SPST-NC) CMOS analog switch optimized for high-fidelity signal routing in 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 battery-powered instrumentation and portable test equipment with minimal signal distortion and board space usage.
For engineers reviewing the DG417DY-T1 datasheet, DG417DY-T1 pinout, DG417DY-T1 application, or DG417DY-T1 equivalent, this page provides verified technical context, package mapping to narrow SOIC-8, confirmed SPST-NC functionality, and real-world selection guidance against functionally aligned alternatives for precision analog switching designs.
Technical Context
The DG417DY-T1 implements a single-channel, normally-closed analog switch using Vishay's high-voltage silicon gate (HVSG) process, enabling robust ±15 V signal handling and 44 V supply rating. Its break-before-make logic is not applicable (DG419 only), and it features complementary control logic to DG418-low input enables conduction, high input disables it.
Designed for bidirectional analog signal integrity, the device exhibits symmetrical on-resistance (20 Ω typ.), sub-0.25 nA off-leakage at full temperature range, and 60 pC charge injection-critical for sample-and-hold and precision instrumentation where signal settling and DC offset stability are essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail bipolar signal switching without clipping in dual-supply precision circuits |
| On-Resistance (RDS(on)) | 20 Ω typical - ensures minimal voltage drop and gain error in low-impedance signal paths |
| Turn-On Time (ton) | 100 ns typical - enables fast multiplexing in data acquisition and automated test equipment |
| Supply Voltage Max | 44 V - accommodates wide industrial supply rails and transient margin in harsh environments |
| Power Dissipation | 35 nW typical - extends battery life in portable medical and field instrumentation |
| Charge Injection | 60 pC - limits output voltage glitch in sample-and-hold and switched-capacitor circuits |
| Off-Leakage Current | ±0.25 nA max (–40 °C to +85 °C) - preserves accuracy in high-impedance sensor front-ends |
Pinout & Package
Narrow SOIC-8 (JEDEC MS-012) package, 3.9 mm × 4.9 mm footprint, 1.27 mm pitch, 1.75 mm max height - compatible with standard surface-mount assembly and IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Source terminal | Normally connected to load; bidirectional conduction path when switch is enabled |
| 2 (D) | Drain terminal | Normally connected to signal source; completes analog path with S during conduction |
| 3 (NC) | No-connect | Internally unconnected; must remain floating-no external connection permitted |
| 4 (V–) | Negative supply rail | Bias reference for negative analog swing; must be decoupled near pin |
| 5 (GND) | Digital ground | Reference for logic inputs (VL, IN); separate from analog ground in mixed-signal layouts |
| 6 (IN) | Logic control input | Active-low: ≤0.8 V enables switch (ON), ≥2.4 V disables (OFF) |
| 7 (V+) | Positive supply rail | Bias reference for positive analog swing; supports up to +44 V |
| 8 (VL) | Logic supply voltage | Accepts 3 V to 5 V TTL/CMOS logic levels independent of V+/V– rails |
Key Features
| Feature | Design Value |
|---|---|
| High-Voltage Silicon Gate Process | Enables ±15 V analog range and 44 V supply rating while maintaining low RDS(on) and leakage |
| Bidirectional Signal Conduction | Identical on-resistance and capacitance in both directions-ideal for AC-coupled and differential signal paths |
| Ultra-Low Power Operation | 35 nW typical quiescent power allows integration into always-on sensor nodes and energy-harvesting systems |
| TTL/CMOS Logic Compatibility | Supports 3 V to 5 V logic supplies (VL) independent of analog rails-simplifies level-shifting in mixed-voltage systems |
| Epitaxial Latch-Up Protection | Guarantees immunity to latch-up under overvoltage transients per MIL-STD-883, Method 3001 |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST-NC analog switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUA+ | Higher on-resistance (35 Ω), higher charge injection (120 pC), same SO-8 package | Less suitable for sub-µV precision sample-and-hold; acceptable for general-purpose multiplexing | Select DG417DY-T1 when <20 Ω RDS(on) and <70 pC charge injection are required |
| ADG1419BRMZ | SPDT configuration (not SPST-NC), 1.8 Ω RDS(on), 12 V max dual supply, higher power (1.2 mW) | Requires redesign for NC-only topology; better for low-RDS(on) but incompatible pinout and logic | Choose DG417DY-T1 for drop-in replacement in existing SPST-NC layouts with ±15 V signal needs |
Compared with MAX4617EUA+ and ADG1419BRMZ, the DG417DY-T1 uniquely balances ultra-low power (35 nW), precision analog performance (20 Ω, 60 pC), and true SPST-NC functionality in narrow SOIC-8-making it optimal for legacy and new designs prioritizing signal integrity over raw speed or lowest on-resistance alone.

FAQ
What is the logic polarity of the DG417DY-T1 control input?
The DG417DY-T1 uses active-low logic: an input voltage ≤0.8 V at pin 6 (IN) turns the switch ON (conducting between S and D), while ≥2.4 V turns it OFF (open circuit). This complements the DG418's active-high behavior and is explicitly defined in the truth table of the DG417/DG418/DG419 datasheet (Rev. G, p.1).
Does the DG417DY-T1 support single-supply operation?
Yes, the DG417DY-T1 supports single-supply operation from 5 V to 40 V. When operated with V– tied to ground, its analog signal range becomes 0 V to V+, with RDS(on) rising to 40 Ω and ton increasing to 110 ns-verified in the unipolar supply specifications section (p.4 of datasheet S10-1528-Rev. G).
What is the maximum allowable voltage on the DG417DY-T1 analog terminals?
The DG417DY-T1 analog terminals (S and D) tolerate voltages from V– to V+, with absolute maximum ratings of –2 V to (V+) + 2 V. Exceeding these clamps internal diodes; forward current must be limited to 30 mA continuous or 100 mA pulsed (1 ms, 10% duty cycle), per Absolute Maximum Ratings table (p.2).
Is the DG417DY-T1 RoHS-compliant?
Yes, the DG417DY-T1 is RoHS-compliant. The "-T1" suffix denotes tape-and-reel packaging with lead-free (Pb-free) terminations, consistent with Vishay's RoHS-compliant product marking conventions documented in datasheet S10-1528-Rev. G (p.1, Note *).
How does the DG417DY-T1 handle charge injection in sample-and-hold circuits?
The DG417DY-T1 specifies 60 pC typical charge injection (Q), measured with CL = 10 nF, Vgen = 0 V, and Rgen = 0 Ω. This value directly determines the hold-step error magnitude; for a 10 nF hold capacitor, it produces a 6 mV step-critical for designing settling time and amplifier compensation in precision S/H stages.
