Product details
Overview
DG411DY from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch designed for high-speed, low-error signal routing in dual-supply (±15 V) or single-supply (up to 44 V) configurations. It features 25 Ω on-resistance, 110 ns turn-on time, ±15 V analog signal range, break-before-make switching action, and TTL/CMOS-compatible digital control - enabling accurate signal selection in precision data acquisition systems.
For engineers reviewing the DG411DY datasheet, DG411DY pinout, DG411DY application, or DG411DY equivalent, key selection considerations include its 16-pin narrow SOIC package, guaranteed 40–100 Ω rDS(on) over temperature and supply voltage, ultra-low leakage (<5 nA), and compatibility with battery-powered and industrial test equipment requiring rail-to-rail analog handling and minimal charge injection (5 pC).
Technical Context
The DG411DY implements four independent bidirectional SPST switches fabricated on Vishay's high-voltage silicon-gate process with epitaxial latchup protection. Each switch conducts equally in both directions when ON and blocks voltages up to the supply rails when OFF.
It uses complementary control logic (active-low enable): logic "0" (≤0.8 V) turns switches ON; logic "1" (≥2.4 V) turns them OFF. The device supports single-supply operation (V+ = VL, V– = GND) with verified performance at 12 V, and maintains specified timing and on-resistance across –40°C to +85°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±15 V (dual-supply) or 0–12 V (single-supply): supports rail-to-rail analog input/output without clipping. |
| rDS(on) Max | 45 Ω at ±13.5 V, –40°C to +85°C: ensures minimal gain error and channel mismatch in precision instrumentation. |
| tON / tOFF | 240 ns / 160 ns max (full temp range): enables sub-microsecond multiplexing in high-throughput ADC front-ends. |
| Charge Injection | 5 pC typical: reduces settling error and offset drift in sample-and-hold and switched-capacitor circuits. |
| Off-Leakage (ID/OFF) | ±5 nA max at ±15.5 V: preserves accuracy in high-impedance sensor interfaces and electrometer-grade inputs. |
| Supply Voltage Range | V+ to V– ≤ 44 V: allows flexible biasing in industrial power rails, including 24 V and 36 V systems. |
| Logic Supply (VL) | (GND –0.3 V) to (V+) +0.3 V: permits direct interfacing with 3.3 V or 5 V microcontrollers without level shifters. |
Pinout & Package
Package: 16-pin narrow SOIC (width = 3.9 mm), RoHS-compliant, rated for –40°C to +85°C operation.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN1–IN4 | Digital control inputs (active-low); each enables corresponding Sx/Dx switch pair. |
| 5, 6, 12, 13 | S1–S4 | Switch source terminals; bidirectional analog I/O nodes tied to external signal paths. |
| 7, 8, 11, 14 | D1–D4 | Switch drain terminals; bidirectional analog I/O nodes, electrically identical to Sx pins. |
| 9 | V– | Negative supply rail; must be ≥ –16.5 V for full spec compliance; referenced for analog and logic thresholds. |
| 10 | V+ | Positive supply rail; supports up to +16.5 V; defines upper analog and logic voltage limits. |
| 15 | GND | Analog/digital ground reference; separate from V– but must be connected in single-supply mode. |
| 16 | VL | Logic supply input; sets logic threshold (0.8 V / 2.4 V); tied to V+ in single-supply use. |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 25 ns minimum delay between switch openings/closings prevents momentary shorts in multiplexer trees. |
| Ultra-low power dissipation | 0.35 W max at full rating: enables thermal stability in dense PCB layouts and portable instrumentation. |
| Wide dynamic range | 68 dB off-isolation and 85 dB crosstalk rejection: preserves signal integrity in multi-channel simultaneous sampling. |
| Latchup-immune process | Epitaxial isolation layer: eliminates risk of destructive latchup under transient overvoltage or ESD stress. |
| Single-supply capability | Validated operation from 5 V to 44 V unipolar: simplifies power architecture in PLC I/O modules and sensor hubs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Lower rDS(on) (15 Ω typ), but only rated to ±20 V supply; no LCC or military-grade variants available. | Better for low-voltage, high-precision lab equipment; unsuitable for 36 V industrial rails or extended temperature ranges. | Select MAX4617ESE+ when optimizing for lowest on-resistance in commercial-grade 5 V/±12 V systems. |
| ADG411BRZ | Higher leakage (±20 nA max), slower tON (150 ns), but offers enhanced ESD rating (±4 kV HBM) and SPI-compatible variants. | Preferred for medical or harsh EMC environments where robustness outweighs speed/leakage specs. | Choose ADG411BRZ when system-level ESD immunity or digital configurability (e.g., ADG412/413 variants) is required. |
Compared with MAX4617ESE+ and ADG411BRZ, the DG411DY delivers superior supply voltage margin (44 V), tighter leakage control (±5 nA), and proven performance across –40°C to +85°C in narrow SOIC - making it optimal for industrial and battery-operated systems demanding long-term analog fidelity without layout redesign.

FAQ
What is the maximum supply voltage rating for DG411DY?
The DG411DY supports a maximum V+ to V– differential of 44 V. In dual-supply operation, this allows configurations such as ±15 V, ±18 V, or +36 V/–8 V. For single-supply use, V+ may be as high as +44 V with V– tied to GND. Absolute maximum ratings must not be exceeded to ensure reliability and latchup immunity.
Does DG411DY support single-supply operation with 3.3 V logic control?
Yes, DG411DY supports 3.3 V logic control when VL is set to 3.3 V. Its input thresholds are specified down to 0.8 V (logic low) and up to 2.4 V (logic high), fully compatible with standard 3.3 V CMOS outputs. The device maintains full analog performance (±15 V signal range) regardless of VL setting, provided V+ and V– remain within absolute maximum limits.
What is the typical charge injection of DG411DY and why does it matter?
The DG411DY exhibits 5 pC typical charge injection, measured with CL = 10 nF and Vg = 0 V. This parameter directly impacts settling time and DC offset in sample-and-hold, switched-capacitor filters, and multiplexed ADC front-ends. Low charge injection minimizes voltage glitches on high-impedance nodes, preserving measurement accuracy in precision instrumentation using the DG411DY.
Is DG411DY pin-compatible with DG411DJ or DG411AK?
No - DG411DY (16-pin narrow SOIC) shares identical pinout with DG411DJ (16-pin plastic DIP) but differs from DG411AK (16-pin CerDIP) in lead pitch and thermal pad configuration. While electrical functionality and logic mapping match across the DG411 family, mechanical compatibility requires verification of footprint and solder reflow profile for each package variant of DG411DY.
How does DG411DY handle analog signals exceeding the supply rails?
DG411DY includes internal clamping diodes on all Sx, Dx, and INx pins. Signals exceeding V+ or falling below V– forward-bias these diodes, limiting excursion to approximately V+ +0.6 V or V– –0.6 V. To avoid damage or excessive current, external series resistors must limit forward diode current to ≤30 mA continuous or ≤100 mA pulsed (1 ms, 10% duty cycle), as specified in the DG411DY datasheet.
