Product details
Overview
DG417BDJ from Vishay Siliconix is a precision monolithic SPST CMOS analog switch optimized for high-performance signal routing in ±15 V dual-supply systems. It delivers 15 Ω on-resistance, 110 ns turn-on time, and <±0.25 nA off-leakage at full temperature range, enabling accurate signal switching in battery-powered instrumentation and military-grade test equipment.
For engineers reviewing the DG417BDJ datasheet, DG417BDJ pinout, DG417BDJ application, or DG417BDJ equivalent, key selection criteria include guaranteed break-before-make timing (for DG419B only), ±15 V analog signal range, TTL/CMOS logic compatibility, MSOP-8/SOIC-8/MiniDIP package options, and low charge injection (38 pC) critical for sample-and-hold integrity.
Technical Context
The DG417BDJ implements a single-pole single-throw (SPST) switch topology using Vishay's high-voltage silicon gate (HVSG) process, enabling robust operation across ±15 V analog rails. Its complementary control logic (active-low enable) pairs with low RDS(on) and minimal channel-to-channel crosstalk (–88 dB for DG419B variant) to support precision multiplexing without signal degradation.
Designed for zero-power-loss signal path integrity, the device features epitaxial latchup prevention, bidirectional conduction when on, and rail-to-rail blocking capability when off. All specifications-including leakage, switching speed, and on-resistance-are validated over –40 °C to +85 °C per the D-suffix rating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V - supports full-range bipolar signal switching without clipping or clamping in dual-supply systems |
| RDS(on) | 15 Ω typical - ensures minimal voltage drop and signal attenuation for 10 mA analog loads |
| tON | 110 ns max - enables fast settling in high-speed data acquisition and automated test equipment |
| IS(off) | ±0.25 nA max - preserves accuracy in high-impedance sensor interfaces and precision integrators |
| Charge Injection | 38 pC - limits voltage glitch in sample-and-hold circuits with 10 nF hold capacitors |
| Off Isolation (OIRR) | –82 dB at 1 MHz - suppresses coupling between adjacent channels in dense multiplexer layouts |
| Supply Voltage Range | V+ = 20 V, V− = –20 V - provides 5 V headroom for transient protection in industrial environments |
Pinout & Package
DG417BDJ is housed in an 8-pin Plastic MiniDIP (Dual-In-Line) package, measuring 9.02–10.92 mm × 7.62–8.26 mm × 2.79–3.81 mm (L×W×H), with 2.54 mm lead pitch and through-hole mounting compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - S | Source terminal | Bidirectional analog signal input/output node; connects to signal source or load |
| 2 - D | Drain terminal | Bidirectional analog signal input/output node; completes switched path with Pin 1 |
| 3 - V− | Negative supply rail | Bias reference for analog channel; must be decoupled to GND near device |
| 4 - GND | Ground reference | Digital and substrate reference; separate from analog ground in mixed-signal designs |
| 5 - IN | Digital control input | Active-low logic interface; 0.8 V max for logic low, 2.4 V min for logic high |
| 6 - V+ | Positive supply rail | Bias reference for analog channel; supports up to +20 V for transient margin |
| 7 - VL | Logic supply | Independent 5 V digital supply; isolates logic noise from analog rails |
| 8 - NC | No connect | Internally unconnected; must remain floating-no external tie or pull-up/down |
Key Features
| Feature | Design Value |

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 typ), wider supply range (±20 V), but higher charge injection (60 pC) | Less suitable for precision sample-and-hold; better for high-voltage industrial I/O | Select MAX4617ESA+ only if >±15 V analog swing or higher breakdown tolerance is required |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω typ), integrated fault protection, but requires 3.3 V logic supply and lacks VL pin independence | Optimized for low-voltage portable medical devices-not compatible with legacy 5 V logic control | Choose ADG1419BRMZ only when ultra-low on-resistance and fault protection outweigh logic supply flexibility |
Compared with DG417BDJ, MAX4617ESA+ trades precision switching fidelity for extended voltage range, while ADG1419BRMZ sacrifices logic supply independence to achieve sub-ohm RDS(on); DG417BDJ remains optimal for ±15 V, 5 V logic, and low-charge-injection requirements in military and test instrumentation.

FAQ
What is the maximum analog signal voltage range supported by DG417BDJ?
DG417BDJ supports an analog signal range of ±15 V when operated with V+ = +15 V and V− = –15 V. Absolute maximum ratings allow V+ up to +20 V and V− down to –20 V, but specified performance-including RDS(on), leakage, and switching speed-is guaranteed only within the ±15 V range per the datasheet's test conditions. Exceeding ±15 V may degrade precision parameters without violating absolute limits.
Does DG417BDJ require a separate logic supply voltage, and what is its valid range?
Yes, DG417BDJ requires a dedicated logic supply (VL) pin, independent from analog supplies. VL must be connected to a stable 5 V source, as confirmed by truth table operation and specification tables (VIN thresholds defined relative to VL). The device is not rated for VL outside 4.5 V to 5.5 V; applying 3.3 V or 12 V will cause undefined logic behavior or potential damage per the absolute maximum ratings.
Is DG417BDJ pin-compatible with DG418BDJ or DG419BDJ?
No, DG417BDJ is not pin-compatible with DG418BDJ or DG419BDJ. While all three share the same 8-pin MiniDIP footprint and power pin assignments (Pins 3, 4, 6, 7), their signal pin functions differ: DG417BDJ uses Pin 1 (S) and Pin 2 (D) for a single SPST switch, whereas DG419BDJ repurposes Pins 1–4 as S1, S2, D1, D2 for SPDT operation. Swapping them without board revision will result in incorrect signal routing or open-circuit paths.
What is the guaranteed break-before-make timing for DG417BDJ?
DG417BDJ does not implement break-before-make switching-it is a single-pole single-throw (SPST) device with no inherent timing coordination between multiple switches. Break-before-make is explicitly guaranteed only for the DG419B family (SPDT configuration), as stated in the datasheet description and verified in the DG419B truth table and tD specification. DG417BDJ has no tD parameter defined; its switching is purely single-channel ON/OFF control.
Can DG417BDJ operate from a single +12 V supply instead of dual ±15 V rails?
Yes, DG417BDJ can operate from a single +12 V supply (V+ = +12 V, V− = 0 V), as confirmed by the "SPECIFICATIONS" table on page 4 of the datasheet. In this configuration, the analog signal range is 0 V to +12 V, RDS(on) increases to 26 Ω typical, and tON extends to 100 ns. All logic interface levels (VL = 5 V, IN thresholds) remain unchanged, preserving compatibility with standard 5 V microcontrollers.
