Product details
Overview
DG419DY-T1-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-fidelity signal integrity in battery-powered instrumentation and military radios.
For engineers reviewing the DG419DY-T1-E3 datasheet, DG419DY-T1-E3 pinout, DG419DY-T1-E3 application, or DG419DY-T1-E3 equivalent, key selection criteria include guaranteed break-before-make timing (13 ns typical), ultra-low 35 nW power dissipation, ±15 V analog signal range, SOIC-8 packaging, and compatibility with TTL/CMOS logic levels.
Technical Context
The DG419DY-T1-E3 implements a monolithic SPDT switch using Vishay's high-voltage silicon gate (HVSG) process, supporting rail-to-rail analog signals up to ±15 V or 0–12 V. Its epitaxial layer prevents latch-up, and internal clamping diodes protect against overvoltage transients on S/D/IN pins.
Break-before-make operation is guaranteed per datasheet truth table and test circuit Fig. 3, with 13 ns typical delay between switch-off and switch-on transitions. Control logic is active-high: IN = 2.4 V turns SW1 ON/SW2 OFF; IN = 0.8 V reverses state - compatible with standard 5 V logic families.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (dual supply) or 0–12 V (single supply): supports full-rail signal switching without clipping |
| RDS(on) | 20 Ω typical at ±15 V: ensures minimal signal attenuation and gain error in precision gain-setting circuits |
| tON / tOFF | 100 ns / 60 ns typical: enables fast multiplexing in data acquisition and sample-and-hold systems |
| Off-Leakage (IS(off)) | ±0.25 nA max at full temperature range: preserves accuracy in high-impedance sensor interfaces |
| Charge Injection | 60 pC typical: limits voltage step errors in switched-capacitor and integrator applications |
| Supply Current (I+/I−) | 1 μA max at full temperature: enables micropower operation in battery-backed memory retention circuits |
| Package | SOIC-8 narrow (JEDEC MS-012): 5.0 × 4.0 mm footprint, surface-mount compatible, RoHS-compliant (E3 suffix) |
Pinout & Package
DG419DY-T1-E3 uses an 8-pin narrow SOIC package (JEDEC MS-012), with lead pitch 1.27 mm and body dimensions 5.0 mm × 4.0 mm × 1.5 mm. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic: ≥2.4 V enables SW1 (S1→D), ≤0.8 V enables SW2 (S2→D) |
| 2 (S2) | Source 2 terminal | Second analog input path; bidirectional conduction when selected |
| 3 (S1) | Source 1 terminal | Primary analog input path; bidirectional conduction when selected |
| 4 (V−) | Negative supply rail | Supports dual-supply operation down to −15 V; must be connected even in single-supply mode |
| 5 (GND) | Ground reference | Logic ground and substrate reference; separate from analog signal return in mixed-signal layouts |
| 6 (IN) | Digital control input | Same as Pin 1 - duplicate label per datasheet top view; single control line |
| 7 (V+) | Positive supply rail | Supports up to +44 V absolute max; regulates internal level-shifting for logic interface |
| 8 (VL) | Logic supply reference | Accepts 5 V TTL/CMOS logic; decoupling capacitor required for noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 13 ns minimum delay prevents momentary shorting between S1 and S2 paths |
| Rail-to-rail analog range | ±15 V operation allows direct interfacing with op-amp outputs and sensor front-ends without level shifting |
| Ultra-low power consumption | 35 nW typical quiescent power enables >10-year battery life in portable medical devices |
| Latch-up immunity | Epitaxial isolation structure eliminates risk of destructive latch-up under transient overvoltage conditions |
| TTL/CMOS logic compatibility | Direct interface with 5 V microcontrollers and FPGAs without level translators or pull-up resistors |

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 RDS(on) (45 Ω typ), no guaranteed break-before-make, 125 °C max rating | Better suited for industrial PLC I/O modules requiring extended temperature operation | Select when operating above +85 °C ambient; verify timing margins due to lack of B-B-M guarantee |
| ADG1419BRMZ | Lower RDS(on) (1.3 Ω typ), higher supply current (200 μA), requires external logic level translation for 3.3 V control | Preferred for low-distortion audio routing where on-resistance matching and THD matter more than power | Choose for <0.001% THD requirements; accept higher quiescent power and added level-shift components |
Compared with MAX4619ESE+ and ADG1419BRMZ, DG419DY-T1-E3 offers the optimal balance of guaranteed break-before-make timing, ultra-low leakage (<0.25 nA), and micropower operation (35 nW) - making it uniquely suitable for portable precision instrumentation where signal integrity and battery life are co-constrained.

FAQ
What is the maximum supply voltage rating for DG419DY-T1-E3?
DG419DY-T1-E3 has an absolute maximum V+ rating of +44 V and V− rating of −44 V, with recommended operating range of ±15 V dual supply or 0–12 V single supply. Exceeding ±44 V risks permanent damage per Absolute Maximum Ratings table on page 2 of Vishay document 70051.
Does DG419DY-T1-E3 require external pull-up or pull-down resistors on the IN pin?
No. DG419DY-T1-E3 features TTL/CMOS-compatible input thresholds (logic "0" ≤ 0.8 V, logic "1" ≥ 2.4 V) and draws only 0.5 μA max input current. Direct connection to 5 V microcontroller GPIOs is supported without external biasing components.
Is break-before-make timing guaranteed across temperature for DG419DY-T1-E3?
Yes. The datasheet explicitly guarantees break-before-make operation for DG419DY-T1-E3, with tD = 13 ns typical and 5 ns minimum at room temperature (page 3, Dynamic Characteristics). This guarantee holds across the full −40 °C to +85 °C operating range per D-suffix specifications.
Can DG419DY-T1-E3 operate from a single 5 V supply?
No. DG419DY-T1-E3 requires both V+ and V− rails to be powered - even in single-ended signal applications. The minimum dual-supply configuration is V+ = +5 V and V− = 0 V (ground), not V+ = 5 V alone. Unpowered V− causes undefined behavior and potential damage.
What is the thermal derating for DG419DY-T1-E3 in SOIC-8 package?
In SOIC-8 package, DG419DY-T1-E3 has 400 mW maximum power dissipation at TA = 25 °C, derated at 6.5 mW/°C above +75 °C (note d, page 2). At +105 °C ambient, allowable power drops to 400 − (105 − 75) × 6.5 = 205 mW.
