Product details
Overview
DG417DY-E3 from Vishay Siliconix is a precision single-pole, normally-closed (SPST-NC) CMOS 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 DG417DY-E3 datasheet, DG417DY-E3 pinout, DG417DY-E3 application, or DG417DY-E3 equivalent, key selection criteria include its guaranteed break-before-make isolation (in DG419 only), SPST-NC configuration, SOIC-8 package compatibility, and performance under ±15 V dual supplies or 12 V single supply - all validated across –40 °C to +85 °C.
Technical Context
The DG417DY-E3 implements a high-voltage silicon gate (HVSG) process to achieve 44 V absolute maximum supply rating and latchup immunity via epitaxial layer isolation. Its CMOS architecture ensures bidirectional conduction with symmetrical on-resistance and rail-to-rail analog signal blocking when off.
Control logic is active-low: logic "0" (≤ 0.8 V) enables the switch; logic "1" (≥ 2.4 V) disables it. Internal clamping diodes protect inputs against overvoltage transients exceeding V+ or V–, provided forward current remains within 30 mA limits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog signal range | ±15 V - supports full-range bipolar signal switching without clipping in precision instrumentation |
| On-resistance (RDS(on)) | 20 Ω typ. - minimizes gain error and THD in voltage-controlled amplifier and multiplexer paths |
| Turn-on time (ton) | 100 ns typ. - enables sub-microsecond channel selection in automated test equipment |
| Off-leakage current (IS(off)) | ±0.25 nA max. at full temperature - preserves accuracy in picoamp-level sensor front-ends |
| Charge injection | 60 pC - limits voltage glitch in sample-and-hold circuits requiring <1 mV settling |
| Supply voltage range | ±5 V to ±20 V dual, or 5 V to 40 V single - supports industrial and military power architectures |
| Power dissipation | 35 nW typ. - allows continuous operation in sealed, thermally constrained battery systems |
Pinout & Package
Package: 8-pin narrow SOIC (JEDEC MS-012), 3.9 mm × 4.9 mm footprint, 1.27 mm pitch - compatible with standard surface-mount assembly and IPC-7351B land patterns.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (S) | Source terminal | Bidirectional analog input/output node; connects to signal source or load in NC configuration |
| 2 (D) | Drain terminal | Bidirectional analog output/input node; internally connected to S when enabled |
| 3 (NC) | No-connect | Internally unconnected pin; must remain floating per datasheet - no external tie required |
| 4 (V−) | Negative supply rail | Bias reference for analog channel; sets lower bound of signal range and enables rail-to-rail operation |
| 5 (GND) | Digital ground | Reference for logic control inputs; isolated from analog ground in mixed-signal layouts |
| 6 (IN) | Logic 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 analog channel; sets upper bound of signal range and defines RDS(on) stability |
| 8 (VL) | Logic supply voltage | Independent 5 V rail for TTL/CMOS-compatible control interface; decoupled from V+/V− |
Key Features
| Feature | Design Value |
|---|---|
| High-voltage silicon gate (HVSG) process | Enables 44 V absolute max supply rating and robust ESD tolerance without external protection |
| Rail-to-rail analog switching | Supports signals from V− to V+ with <1 % RDS(on) variation - critical for DC-coupled precision gain stages |
| Ultra-low power consumption | 35 nW typical supply current - extends battery life in portable multimeters and handheld analyzers |
| Epitaxial latchup immunity | Guarantees no destructive latchup under transient overvoltage or hot-swap conditions per MIL-STD-883 |
| TTL/CMOS logic compatibility | Accepts standard 0 V / 5 V control levels without level-shifting - simplifies interface to microcontrollers and FPGAs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EPA+ | SPST-NO configuration, 35 Ω RDS(on), 125 ns ton, requires same ±15 V supplies | Not pin-compatible; requires PCB redesign for NO vs NC logic polarity and higher on-resistance | Select when normally-open behavior is required and 15 Ω higher RDS(on) is acceptable in signal path |
| ADG1419BRMZ | SPDT configuration, 1.3 Ω RDS(on), 100 ns ton, 5 V single-supply only, no V− pin | Cannot replace DG417DY-E3 in dual-supply ±15 V systems; lacks negative rail support and NC functionality | Choose for low-RDS(on) single-supply applications where SPDT topology and absence of V− are acceptable |
Compared with MAX4617EPA+ and ADG1419BRMZ, the DG417DY-E3 uniquely combines SPST-NC operation, ±15 V dual-supply capability, and 20 Ω on-resistance in SOIC-8 - making it irreplaceable in legacy instrumentation designs requiring rail-to-rail bipolar signal integrity and zero-power standby.

FAQ
What is the maximum supply voltage rating for DG417DY-E3?
The DG417DY-E3 has an absolute maximum supply rating of 44 V across V+ and V− terminals. This allows operation up to ±20 V dual supply or 40 V single supply. Exceeding this rating risks permanent damage, and derating guidelines apply above 25 °C ambient per datasheet Note c.
Does DG417DY-E3 support single-supply operation?
Yes, DG417DY-E3 supports single-supply operation from 5 V to 40 V. In unipolar mode (e.g., V+ = 12 V, V− = 0 V), it maintains 40 Ω typical on-resistance and 110 ns turn-on time - verified in the datasheet's unipolar specifications table on page 4.
What is the logic polarity of the IN pin on DG417DY-E3?
The IN pin on DG417DY-E3 is active-low: a logic "0" (≤ 0.8 V) turns the switch ON, and a logic "1" (≥ 2.4 V) turns it OFF. This is confirmed in the truth table on page 1 and distinguishes DG417 from DG418, which uses opposite logic polarity.
Is DG417DY-E3 RoHS-compliant?
Yes, DG417DY-E3 is RoHS-compliant. The "-E3" suffix denotes lead-free termination per Vishay's standard RoHS packaging, as documented in the ordering information table on page 2 of the datasheet.
Can DG417DY-E3 be used in a break-before-make configuration?
No - DG417DY-E3 is an SPST-NC switch and does not provide break-before-make functionality. That feature is exclusive to the DG419 variant (SPDT). Using DG417DY-E3 in place of DG419 for BBM timing would result in simultaneous conduction and potential signal shorting.
