Product details
Overview
DG417BDJ-E3 from Vishay Siliconix is a precision monolithic single-pole single-throw (SPST) CMOS analog switch optimized for bidirectional signal routing in high-fidelity analog paths. It delivers ±15 V analog signal range, 15 Ω typical on-resistance at ±15 V supplies, 110 ns turn-on time, and operates across –40 °C to +85 °C - making it suitable for battery-powered instrumentation and precision test equipment where low leakage and minimal charge injection are critical.
For engineers reviewing the DG417BDJ-E3 datasheet, DG417BDJ-E3 pinout, DG417BDJ-E3 application, or DG417BDJ-E3 equivalent, key selection criteria include guaranteed break-before-make timing (in DG419B only), absence of latch-up due to epitaxial layer, TTL/CMOS logic compatibility, and MSOP-8/SOIC-8/MiniDIP package options - all validated for industrial-grade reliability under dual-supply operation.
Technical Context
The DG417BDJ-E3 implements a high-voltage silicon gate (HVSG) process enabling ±15 V analog rail operation while maintaining low RDS(on) and sub-100 nA off-leakage. Its control logic is active-high: logic "1" (≥2.4 V) disables the switch, logic "0" (≤0.8 V) enables conduction - opposite to DG418B.
Each channel conducts equally in both directions when on and blocks signals up to the supply rails when off. Internal clamping diodes protect against overvoltage transients on S/D/IN pins, with forward current limited per absolute maximum ratings.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-rail analog signal switching without clipping in dual-supply systems |
| RDS(on) | 15 Ω typ. - ensures minimal signal attenuation and distortion in precision gain paths |
| tON | 110 ns max. - enables fast multiplexing in data acquisition and sampling circuits |
| IS(off) | ±0.25 nA max. - preserves accuracy in high-impedance sensor interfaces and sample-and-hold stages |
| Charge Injection | 38 pC - limits voltage glitch on sampled nodes, critical for ADC front-end integrity |
| Off Isolation (OIRR) | –82 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel systems |
| Supply Voltage Range | V+ = 20 V max., V− = –20 V max. - accommodates wide dynamic range signal conditioning |
Pinout & Package
Package: 8-Pin Plastic MiniDIP (also designated as DIP-8 or MiniDIP-8), body dimensions 9.02 × 7.62 mm, lead pitch 2.54 mm, RoHS-compliant matte tin finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - S | Source terminal | Bidirectional analog input/output node; connects to signal source or load |
| 2 - D | Drain terminal | Bidirectional analog input/output node; complements S in SPST configuration |
| 3 - V− | Negative supply rail | Bias reference for analog channel; must be ≤ –20 V absolute max |
| 4 - GND | Ground reference | Logic and substrate reference; separate from analog ground in mixed-signal layouts |
| 5 - IN | Digital control input | Active-low enable: logic "0" (≤0.8 V) turns switch ON; logic "1" (≥2.4 V) turns OFF |
| 6 - V+ | Positive supply rail | Bias reference for analog channel; must be ≥ +20 V absolute max |
| 7 - VL | Logic supply voltage | Independent 5 V logic rail; decoupling required to minimize digital noise coupling |
| 8 - NC | No connect | Internally unconnected; must remain floating or tied to GND per layout best practice |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EPA+ | Higher RDS(on) (35 Ω typ.), wider supply range (±20 V), but higher charge injection (60 pC) | Less suitable for sub-16-bit sample-and-hold; better for general-purpose switching with higher voltage margin | Select when ±20 V operation is mandatory and charge injection tolerance >60 pC |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω typ.), lower leakage (±1 pA), but requires 3.3 V logic and lacks VL pin independence | Requires logic-level translation in 5 V systems; superior for low-noise, low-distortion audio or RF paths | Select when ultra-low on-resistance and femtoamp leakage outweigh logic compatibility needs |
Compared with DG417BDJ-E3, MAX4617EPA+ trades lower leakage and higher voltage tolerance for increased charge injection and on-resistance, while ADG1419BRMZ offers dramatically lower RDS(on) and leakage but sacrifices 5 V logic autonomy and increases cost and complexity in legacy 5 V control environments.

FAQ
What is the logic polarity of DG417BDJ-E3?
The DG417BDJ-E3 uses active-low logic control: applying logic "0" (≤0.8 V) to the IN pin turns the switch ON, while logic "1" (≥2.4 V) turns it OFF. This is inverted relative to DG418B, and confirmed in the Truth Table on page 1 of Document Number 72107. The DG417BDJ-E3 datasheet specifies this behavior explicitly for the DG417B variant.
Does DG417BDJ-E3 support single-supply operation?
Yes, DG417BDJ-E3 supports single-supply operation with V+ = 12 V and V− = 0 V, delivering 0–12 V analog signal range and 26 Ω typical RDS(on). Performance metrics including tON (100 ns max) and leakage (±0.25 nA max) are specified under these conditions in the "SPECIFICATIONS" table on page 4 of the datasheet.
Is the NC pin on DG417BDJ-E3 required to be grounded?
No, the NC (pin 8) on DG417BDJ-E3 is internally unconnected and must remain floating. Vishay documentation does not recommend grounding it; doing so may introduce parasitic capacitance or noise coupling. Layout guidelines advise leaving NC pins unconnected unless specified otherwise in application notes - which is not the case for DG417BDJ-E3.
What is the maximum allowable logic supply voltage VL for DG417BDJ-E3?
The DG417BDJ-E3 specifies VL = (GND – 0.3 V) to (V+) + 0.3 V per Absolute Maximum Ratings (page 2). For standard operation with V+ = 15 V, VL may range from –0.3 V to +15.3 V. However, functional operation is guaranteed only at VL = 5 V, as all dynamic and leakage specs are tested at that level.
How does DG417BDJ-E3 prevent latch-up?
DG417BDJ-E3 prevents latch-up via an epitaxial layer integrated into its high-voltage silicon gate (HVSG) process, as stated in the DESCRIPTION section (page 1). This structural feature eliminates parasitic SCR formation under overvoltage or ESD stress - a key reliability differentiator versus non-epitaxial analog switches - and is verified per JEDEC JESD78 latch-up testing.
