Product details
Overview
DG419DY-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 - enabling high-accuracy signal path control in battery-powered instrumentation and military radios.
For engineers reviewing the DG419DY-E3 datasheet, DG419DY-E3 pinout, DG419DY-E3 application, or DG419DY-E3 equivalent, key selection criteria include guaranteed break-before-make timing (13 ns typ.), ultra-low 35 nW power dissipation, ±15 V analog signal range, SOIC-8 package compatibility, and TTL/CMOS logic interface support.
Technical Context
The DG419DY-E3 implements a monolithic SPDT switch architecture using Vishay's high-voltage silicon gate (HVSG) process, enabling 44 V supply rating and latchup immunity via epitaxial isolation. Its control logic accepts standard TTL/CMOS levels (0.8 V low / 2.4 V high) and drives two independent switch paths with complementary activation.
Break-before-make operation is electrically guaranteed across temperature (–40 °C to +85 °C), with 13 ns typical delay between channel deactivation and reactivation. Signal conduction is symmetrical (S1↔D and S2↔D), supporting rail-to-rail analog signals up to ±15 V or 0–12 V without distortion.
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 minimal gain error and voltage drop in precision signal paths) |
| Turn-on time (ton) | 100 ns (enables fast multiplexing in data acquisition and test equipment) |
| Off-leakage current (IS(off)) | ±0.25 nA max (preserves accuracy in high-impedance sample-and-hold circuits) |
| Supply voltage range | ±5 V to ±20 V dual or 5–40 V single (flexible integration into legacy and low-power systems) |
| Power dissipation | 35 nW (enables operation in energy-constrained portable and remote sensors) |
| Charge injection | 60 pC (minimizes settling error in precision ADC front-ends) |
Pinout & Package
DG419DY-E3 is housed in an 8-pin narrow SOIC package (JEDEC MS-012), 3.9 mm × 4.9 mm footprint, 1.75 mm height, with 1.27 mm lead pitch. Pin 1 marked by bevelled corner.

| 2 (S2) | Source 2 terminal | Second analog input/output node for SPDT configuration |
| 3 (S1) | Source 1 terminal | Primary analog input/output node; connects to D when IN = 0 |
| 4 (V−) | Negative supply rail | Bias reference for negative analog swing; supports –15 V operation |
| 5 (GND) | Ground reference | Logic ground and substrate reference; separate from analog return in mixed-signal layouts |
| 6 (V+) | Positive supply rail | Bias reference for positive analog swing; supports +15 V operation |
| 7 (VL) | Logic supply voltage | Independent 5 V rail for TTL/CMOS-compatible control interface |
| 8 (D) | Drain/common terminal | Shared analog I/O port; routes signal from selected source (S1 or S2) |
Key Features
| Feature | Design Value |

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 35 Ω RDS(on), 125 ns ton, no guaranteed break-before-make | Lower cost; suitable where timing overlap tolerance exists | Select for cost-sensitive industrial controls where precise channel separation is non-critical |
| ADG1419BRUZ | Lower 4.7 Ω RDS(on), 150 ns ton, ±16.5 V rating, higher 1.2 μA IQ | Higher performance but consumes >30× more quiescent power | Select for high-precision lab equipment where on-resistance dominates error budget |
Compared with MAX4619ESE+ and ADG1419BRUZ, DG419DY-E3 uniquely balances ultra-low power (35 nW), guaranteed break-before-make, and 20 Ω on-resistance - making it optimal for portable, battery-constrained, and safety-critical signal routing where both timing integrity and efficiency matter.

FAQ
What is the guaranteed break-before-make time for DG419DY-E3?
The DG419DY-E3 guarantees a minimum break-before-make time delay of 5 ns over its full operating temperature range (–40 °C to +85 °C), with 13 ns typical at 25 °C. This specification ensures no simultaneous conduction between S1 and S2 paths during switching transitions, preventing signal shorting in critical analog routing applications. The value is measured under standard test conditions (RL = 300 Ω, CL = 35 pF, VS1 = VS2 = ±10 V) per Vishay document 70051.
Does DG419DY-E3 support single-supply operation?
Yes, DG419DY-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 while preserving rail-to-rail analog signal handling (0–12 V). The VL pin must still be supplied with 5 V for TTL/CMOS logic compatibility, and all absolute maximum ratings (e.g., 44 V supply limit) remain applicable regardless of supply configuration.
What is the maximum analog signal voltage range for DG419DY-E3?
The DG419DY-E3 supports a maximum analog signal range of ±15 V when operated with dual supplies (V+ = +15 V, V− = –15 V), or 0–12 V with single supply (V+ = 12 V, V− = 0 V). Signals exceeding these limits are clamped by internal diodes; forward diode current must be limited to rated maximums. The ±15 V range is fully specified and tested per Vishay datasheet 70051, ensuring linearity and low distortion across the entire span.
How does DG419DY-E3 achieve latchup immunity?
DG419DY-E3 achieves latchup immunity through an epitaxial layer integrated into Vishay Siliconix's high-voltage silicon gate (HVSG) process. This structural feature prevents parasitic SCR formation between adjacent P-N junctions under transient stress or overvoltage conditions. The design is verified per JEDEC JESD78 Class II requirements, and no latchup has been observed in qualification testing across –40 °C to +125 °C ambient temperatures.
Is DG419DY-E3 RoHS-compliant?
Yes, DG419DY-E3 is RoHS-compliant. The "-E3" suffix denotes lead-free termination and compliance with Directive 2011/65/EU. Per Vishay document 70051, this part uses matte tin plating over copper leadframe and meets all substance restrictions, including Pb < 1000 ppm. Full compliance documentation, including test reports and material declarations, is available upon request from Aetrix Electronics or directly from Vishay.
