Product details
Overview
DG411LDY-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch in 16-pin narrow SOIC package, operating on single supply (2.7–12 V) or dual supply (±3–±6 V), with 17 Ω typical RDS(on), 19 ns tON, and 12 ns tOFF, used for high-fidelity audio/video signal routing in battery-powered test equipment.
For engineers reviewing the DG411LDY-E3 datasheet, DG411LDY-E3 pinout, DG411LDY-E3 application, or DG411LDY-E3 equivalent, key selection considerations include guaranteed break-before-make timing, ±2000 V ESD protection, sub-1 pC charge injection at 3 V, and compatibility with TTL/CMOS logic levels across full industrial temperature range (–40 °C to +85 °C).
Technical Context
The DG411LDY-E3 implements four independent normally-open analog switches using BiCMOS fabrication, enabling flat on-resistance over full analog signal range (0–12 V single supply, ±5 V dual supply) and minimal distortion in precision signal paths. Its control logic is active-high: INx = logic "1" (≥2.4 V) turns corresponding switch ON.
It features integrated level-shifting circuitry referenced to VL pin, allowing digital control voltage (e.g., 3.3 V or 5 V) to operate switches powered by higher analog supplies (up to 12 V or ±6 V), while maintaining guaranteed switching performance and <0.25 nA off-state leakage at room temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 17 Ω typical at V+ = 12 V - ensures low insertion loss & minimal signal attenuation in audio/video paths |
| tON/tOFF | 19 ns / 12 ns at V+ = 12 V - supports fast multiplexing in data acquisition and communication systems |
| Analog Range | 0 to 12 V (single supply) or ±5 V (dual supply) - matches full rail-to-rail signal handling in precision instrumentation |
| Charge Injection | 5 pC typical at V+ = 12 V - limits voltage glitch on sampled nodes in ADC front-ends |
| Off-Isolation | 71 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-signal routing |
| ESD Protection | 2000 V HBM - enables robust handling in automated PCB assembly and field-replaceable modules |
| Logic Compatibility | TTL/CMOS - simplifies interface with microcontrollers, FPGAs, and legacy logic without level shifters |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), body dimensions 9.9 mm × 3.9 mm × 1.5 mm, RoHS-compliant, lead-free (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | Active-high logic: ≥2.4 V = ON state; referenced to VL, not V+ or GND |
| S1–S4 | Switch source terminal | Analog input node; bidirectional current flow; clamped to V+/V− by internal diodes |
| D1–D4 | Switch drain terminal | Analog output node; matched impedance and capacitance to S pins for balanced routing |
| V+ | Positive analog supply | Accepts 2.7–12 V single or +3–+6 V dual; powers analog channel core |
| V− | Negative analog supply | Accepts 0 V (ground) or –3––6 V; enables bipolar signal switching |
| GND | Ground reference | Return path for logic and analog supplies; separate from power ground in mixed-signal layouts |
| VL | Logic supply reference | Defines logic threshold (0.8 V low / 2.4 V high); accepts 2.7–5.5 V independent of V+/V− |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 6 ns minimum delay between turn-off of one channel and turn-on of another - prevents momentary shorting in multiplexer configurations |
| Flat RDS(on) vs. signal voltage | ≤5 Ω variation across full analog range - maintains consistent gain and linearity in precision amplifiers and filters |
| Low charge injection | 0.5 pC typical at 3 V supply - reduces sampling error in 16-bit+ data acquisition systems |
| High off-isolation | 68–71 dB up to 1 MHz - isolates sensitive analog inputs from noisy digital or RF sections |
| Wide supply flexibility | Operates on 2.7–12 V single or ±3–±6 V dual - eliminates need for dedicated analog rails in portable instruments |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Single-supply only (2.7–5.5 V); 35 Ω RDS(on); 125 ns tON; no dual-supply support | Lower voltage, lower speed - suitable only for 3.3 V embedded control, not precision ±5 V systems | Select when cost sensitivity outweighs speed/leakage requirements and dual supply is unnecessary |
| ADG1411BRUZ | 1.5 Ω RDS(on) at 5 V; 17 ns tON; ±15 V max rating; requires external logic level translation for 3.3 V control | Higher performance but higher supply voltage and layout complexity - better for high-end instrumentation | Select when ultra-low on-resistance and sub-pC charge injection justify added BOM and layout effort |
Compared with MAX4617ESE+, DG411LDY-E3 delivers 2× faster switching and dual-supply capability critical for bipolar signal chains; versus ADG1411BRUZ, it offers native 3.3 V logic compatibility and lower system integration overhead despite higher RDS(on).

FAQ
What supply voltages does the DG411LDY-E3 support?
The DG411LDY-E3 supports single supply from 2.7 V to 12 V (e.g., 3.3 V or 5 V logic with 12 V analog rails) or dual supply from ±3 V to ±6 V (e.g., ±5 V for bipolar signal handling). The VL pin accepts 2.7–5.5 V independently, enabling direct interfacing with 3.3 V microcontrollers even when V+ is at 12 V. This flexibility is confirmed in the Absolute Maximum Ratings and Electrical Characteristics tables of Vishay Document 71397.
Does DG411LDY-E3 have break-before-make functionality?
Yes, the DG411LDY-E3 guarantees break-before-make timing - specifically 6 ns minimum delay between turn-off of one channel and turn-on of another - but only for the DG413L variant. The DG411LDY-E3 is a quad SPST device with independent switches and no inherent inter-channel timing coordination. Break-before-make behavior must be implemented externally via control sequencing. This distinction is explicitly stated in the Truth Table and Functional Block Diagram sections of the DG411L datasheet.
What is the maximum analog signal voltage the DG411LDY-E3 can handle?
The DG411LDY-E3 supports analog signals from 0 V to V+ (single supply) or from V− to V+ (dual supply), with absolute maximum ratings of –0.3 V to (V+) + 0.3 V on S/D pins. At V+ = 12 V, the usable analog range is 0–12 V; at ±5 V dual supply, it is –5 V to +5 V. Signals exceeding these ranges are clamped by internal diodes, and forward current must be limited to 30 mA continuous per terminal, as specified in the Absolute Maximum Ratings table.
Is DG411LDY-E3 pin-compatible with the legacy DG411?
Yes, the DG411LDY-E3 is explicitly described as a low-voltage pin-for-pin compatible companion to the industry-standard DG411, with improved performance including lower RDS(on), faster switching, and enhanced ESD protection. The pin configuration diagram, truth table, and ordering information in Document 71397 confirm identical 16-pin SOIC layout and signal mapping (IN1–IN4, S1–S4, D1–D4, V+, V−, GND, VL) between DG411LDY-E3 and DG411.
What is the leakage current specification for DG411LDY-E3 at 85 °C?
At full industrial temperature range (–40 °C to +85 °C), the DG411LDY-E3 guarantees switch off-leakage current (IS(off)) of ±10 nA maximum, and channel-on leakage (ID(on)) of ±10 nA maximum, as specified in the D-Suffix Limits column of the Single Supply 12 V specifications table. These values are tested under worst-case conditions (VD = 1/11 V, VS = 11/1 V) and represent production-tested limits, not typical values.
