Product details
Overview
DG419DJ-E3 from Vishay Siliconix is a precision SPDT CMOS analog switch optimized for bidirectional signal routing in ±15 V dual-supply or 12 V single-supply systems. It delivers 20 Ω on-resistance, 100 ns turn-on time, break-before-make switching, and <0.25 nA off-leakage at full temperature range, enabling high-accuracy signal path control in battery-powered instrumentation and military radios.
For engineers reviewing the DG419DJ-E3 datasheet, DG419DJ-E3 pinout, DG419DJ-E3 application, or DG419DJ-E3 equivalent, key selection criteria include guaranteed break-before-make timing (13 ns min), ±15 V analog signal range, ultra-low 35 nW power dissipation, and compatibility with TTL/CMOS logic levels - all critical for precision test equipment and sample-and-hold circuits requiring minimal signal distortion and leakage.
Technical Context
The DG419DJ-E3 implements a monolithic SPDT switch architecture built on Vishay's high-voltage silicon gate (HVSG) process, enabling 44 V supply rating and latchup immunity via epitaxial isolation. Its control logic follows standard active-high behavior: IN = 0 V turns SW1 ON/SW2 OFF; IN = 5 V reverses state.
Break-before-make operation is electrically guaranteed across -40 °C to +85 °C, with tD ≥ 5 ns (typ. 13 ns) under RL = 300 Ω, CL = 35 pF, and ±10 V analog signals. Charge injection is specified at 60 pC, supporting low-error sampling in precision data acquisition paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog signal range | ±15 V (supports full-rail bipolar signal switching without clipping) |
| On-resistance (RDS(on)) | 20 Ω (ensures <0.1% gain error in 10 kΩ load applications) |
| Turn-on time (ton) | 100 ns (enables ≤10 MHz multiplexed signal routing) |
| Off-leakage current (IS(off)) | ±0.25 nA max (preserves integrity of picoamp-level sensor signals) |
| Supply voltage range | ±15 V dual or 12 V single (supports industrial and military power architectures) |
| Logic compatibility | TTL/CMOS (direct interface with microcontrollers and FPGAs without level shifters) |
| Charge injection | 60 pC (limits voltage glitch to <6 µV on 10 nF hold capacitors) |
Pinout & Package
DG419DJ-E3 uses an 8-pin plastic MiniDIP package (JEDEC MS-001) with 0.3-inch body width, 2.54 mm lead pitch, and through-hole mounting. Pin 1 is top-left corner marked with dot or notch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic: 0 V = SW1 ON, 5 V = SW2 ON |
| 2 (D) | Common drain terminal | Bidirectional analog path shared by both switches |
| 3 (S2) | Source 2 terminal | Second analog output path; connects to D when IN = 5 V |
| 4 (S1) | Source 1 terminal | First analog output path; connects to D when IN = 0 V |
| 5 (V–) | Negative supply rail | Reference for negative analog swing; must be connected even in single-supply use |
| 6 (GND) | Logic ground | Return for digital control signals and VL supply |
| 7 (V+) | Positive supply rail | Reference for positive analog swing; supports up to +44 V |
| 8 (VL) | Logic supply input | Accepts 3 V to 5 V to set input threshold; decouples logic from analog rails |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 5 ns minimum delay prevents signal shorting during transition |
| Ultra-low power consumption | 35 nW typical quiescent dissipation extends battery life in portable systems |
| High-voltage silicon gate process | Enables 44 V absolute max supply rating and robust ESD tolerance |
| Bidirectional conduction | Identical RDS(on) and leakage in both directions simplifies AC signal routing |
| Latchup immunity | Epitaxial layer eliminates risk of destructive latchup under overvoltage transients |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4619ESE+ | Higher 45 Ω RDS(on), 125 ns ton, no guaranteed break-before-make | Lower cost for non-critical signal routing where timing overlap is acceptable | Select when budget constraints outweigh need for guaranteed transition safety |
| ADG1419BRUZ | Lower 4.7 Ω RDS(on), 150 ns ton, ±15 V compatible but requires external charge pump for VL | Higher precision in low-impedance sensor interfaces where on-resistance dominates error | Select when <5 Ω RDS(on) is mandatory and board space allows auxiliary circuitry |
Compared with MAX4619ESE+ and ADG1419BRUZ, DG419DJ-E3 uniquely balances guaranteed break-before-make timing, ultra-low leakage, and self-contained logic supply (VL pin), making it optimal for battery-powered instrumentation where reliability, power, and signal integrity are co-constrained.

FAQ
What is the maximum supply voltage rating for DG419DJ-E3?
DG419DJ-E3 supports up to +44 V on V+ and down to -44 V on V–, with absolute maximum ratings defined as V+ ≤ +44 V and V– ≥ -44 V. Operation beyond ±15 V analog range is permitted only if signal voltages remain within the supply rails, and internal clamping diodes limit forward current to rated values per datasheet Note a.
Does DG419DJ-E3 require separate logic and analog ground connections?
No - DG419DJ-E3 uses a single GND pin for logic return, shared with VL supply. V– serves as the analog negative rail and must be tied to system analog ground if using dual supplies. The design integrates logic and analog grounds internally, eliminating need for split-ground layout in most implementations.
Can DG419DJ-E3 operate from a single 12 V supply?
Yes - DG419DJ-E3 supports unipolar operation with V+ = 12 V, V– = 0 V, and VL = 5 V. In this configuration, the analog signal range is 0 V to 12 V, RDS(on) increases to 40 Ω, and ton is 110 ns. All timing and leakage specs remain valid across -40 °C to +85 °C.
What is the purpose of the VL pin on DG419DJ-E3?
The VL pin on DG419DJ-E3 sets the logic threshold voltage independently of V+ and V–, accepting 3 V to 5 V to define VIN(H) ≥ 2.4 V and VIN(L) ≤ 0.8 V. This decouples digital interface requirements from analog supply rails, enabling reliable control even when V+ and V– are asymmetric or extended beyond standard logic levels.
Is DG419DJ-E3 pin-compatible with other devices in the DG417/DG418/DG419 family?
Yes - DG419DJ-E3 shares identical 8-pin MiniDIP pinout with DG417DJ-E3 and DG418DJ-E3, including matching IN, D, S1/S2, V+, V–, GND, and VL assignments. However, logic polarity differs: DG417 is normally-on, DG418 is normally-off, while DG419 is SPDT with complementary switching - PCB layout reuse is possible but firmware logic must be verified.
