Product details
Overview
DG411HSDY-T1 from Vishay Siliconix is a precision monolithic quad SPST CMOS analog switch designed for high-speed, low-error switching of bipolar ±15 V analog signals in portable and battery-powered systems. It features 25 Ω on-resistance, 68 ns turn-on time, 0.35 µW ultra-low power dissipation, and operates from ±15 V dual supplies or 12 V single supply.
For engineers reviewing the DG411HSDY-T1 datasheet, DG411HSDY-T1 pinout, DG411HSDY-T1 application, or DG411HSDY-T1 equivalent, key selection criteria include guaranteed break-before-make timing, ±15 V signal range compatibility, SOIC-16 package thermal performance (600 mW at 25 °C), and TTL/CMOS logic interface support without level-shifting.
Technical Context
The DG411HSDY-T1 implements four independent normally-open (NO) SPST switches fabricated on Vishay's high-voltage silicon gate process with epitaxial latchup protection. Each channel conducts bidirectionally with matched on-resistance and exhibits symmetrical off-isolation (>91 dB at 1 MHz) and low charge injection (22 pC).
Control logic follows active-high enable: INx = logic high disables the corresponding Sx–Dx path. The device supports single-supply operation (V+ = 12 V, V− = 0 V) with reduced but specified performance-RDS(on) up to 100 Ω and tON up to 180 ns-while maintaining full ±15 V analog signal handling capability under dual-supply conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±15 V dual supply or 12 V single supply - enables direct interfacing with industrial ±10 V sensor outputs and 3.3/5 V logic without external level shifters |
| On-Resistance (RDS(on)) | 25 Ω typical at ±15 V - ensures <0.1% gain error in 10 kΩ precision signal paths and minimal THD degradation |
| Turn-On Time (tON) | 68 ns typical at ±15 V - supports multiplexing of DC to >1 MHz analog signals with sub-1 LSB settling in 16-bit data acquisition |
| Analog Signal Range | ±15 V - fully covers industrial process control (4–20 mA loop-derived voltages) and audio line-level signals |
| Power Dissipation | 0.35 µW quiescent - extends battery life in handheld test equipment and portable medical monitors |
| Off-Isolation (OIRR) | −91 dB at 1 MHz - prevents crosstalk between adjacent channels in multi-channel DAQ front-ends |
| Charge Injection | 22 pC - limits voltage glitch to <2.2 mV on 10 nF sample capacitors used in SAR ADC hold circuits |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 3.9 mm × 9.9 mm body, 1.27 mm pitch, 1.75 mm max height. Rated for 600 mW power dissipation at 25 °C with 7.6 mW/°C derating above 75 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | Active-high logic enables corresponding switch; compatible with 3.3 V/5 V TTL and CMOS drivers without pull-ups |
| S1–S4 | Switch source terminal | Bidirectional analog input node; accepts ±15 V signals and routes to D1–D4 when enabled |
| D1–D4 | Switch drain terminal | Bidirectional analog output node; connects to Sx when INx = high, blocks at ±15 V when off |
| V+ | Positive supply rail | Connects to +15 V (dual) or +12 V (single); must be decoupled locally to suppress switching transients |
| V− | Negative supply rail | Connects to −15 V (dual) or GND (single); provides return path for analog signal current |
| GND | Digital ground reference | Logic ground return; isolated from analog signal path but tied to V− in single-supply configurations |
| VL | Logic supply reference | Accepts 5 V logic supply; separates digital switching threshold from analog rails to prevent noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed 20 ns minimum delay between turn-off of one channel and turn-on of another - eliminates momentary short-circuits in multiplexer crosspoint routing |
| Ultra-low quiescent power | 0.35 µW typical - reduces self-heating to <0.001 °C in sealed enclosures, preserving offset stability in precision instrumentation |
| High-voltage silicon gate process | 44 V max V+–V− rating - supports operation across extended temperature range (−40 °C to +85 °C) with no parameter drift beyond spec limits |
| Epitaxial latchup immunity | Rated for continuous operation under IEC 61000-4-2 ESD stress (±2 kV contact) - eliminates need for external protection diodes in Class B industrial environments |
| TTL/CMOS logic compatibility | Validated down to 0.8 V VIH min and 2.4 V VOH min - ensures robust operation with legacy microcontrollers and FPGA I/O banks |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Lower RDS(on) (15 Ω), higher supply current (1 µA), no VL pin - requires shared V+ for logic and analog rails | Better for low-offset op-amp multiplexing; unsuitable where logic/analog ground separation is required | Select MAX4617ESE+ only if system uses single 5 V rail and prioritizes on-resistance over isolation integrity |
| ADG1412BRUZ | Higher voltage rating (±20 V), faster switching (12 ns tON), but larger 16-lead TSSOP package and 1.2 µW quiescent power | Preferred for high-speed automated test systems needing <20 ns channel switching; less optimal for space-constrained portable designs | Choose ADG1412BRUZ when tON < 20 ns is mandatory and PCB area allows 5 mm × 4.4 mm footprint |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG411HSDY-T1 uniquely balances ultra-low power (0.35 µW), ±15 V signal integrity, and SOIC-16 manufacturability-making it the optimal choice for battery-powered precision instruments where thermal management and layout simplicity are critical.

FAQ
What is the maximum analog signal voltage the DG411HSDY-T1 can handle?
The DG411HSDY-T1 supports an analog signal range of ±15 V when operated from ±15 V dual supplies. This is explicitly specified in the datasheet under "Analog Signal Range" with min/max values of −15 V to +15 V. Signals exceeding these levels are clamped by internal diodes, so external limiting is required beyond this range. The DG411HSDY-T1 maintains full performance within this window across its −40 °C to +85 °C operating temperature range.
Does the DG411HSDY-T1 require separate logic and analog grounds?
No, the DG411HSDY-T1 does not require separate logic and analog grounds. Its VL pin accepts a dedicated 5 V logic supply but references internally to the same ground plane as V− and GND. The datasheet shows GND tied directly to V− in all functional diagrams, confirming a single ground connection point. This simplifies PCB layout while maintaining noise immunity via the isolated VL rail.
Can the DG411HSDY-T1 operate from a single 5 V supply?
No, the DG411HSDY-T1 cannot operate from a single 5 V supply. Its absolute maximum V+–V− rating is 44 V, but the minimum functional dual-supply configuration is ±5 V, and the minimum unipolar supply is 12 V (V+ = 12 V, V− = 0 V). At 5 V, the device fails to meet RDS(on) and tON specifications - the datasheet provides no characterization data below 12 V unipolar or ±5 V dual, and attempting 5 V operation risks incomplete channel turn-on and increased distortion.
What is the thermal derating behavior of the DG411HSDY-T1 in SOIC package?
The DG411HSDY-T1 in narrow SOIC package has a power dissipation rating of 600 mW at 25 °C, with linear derating of 7.6 mW/°C above 75 °C. This means usable power drops to 456 mW at 95 °C and 304 mW at 115 °C. These values are confirmed in the "Absolute Maximum Ratings" table under "Power Dissipation (Package)" for 16-Pin Narrow SOIC. No derating is applied between 25 °C and 75 °C.
Is the DG411HSDY-T1 pin-compatible with older DG411 variants like DG411DJ?
Yes, the DG411HSDY-T1 is pin-compatible with the through-hole DG411DJ variant. Both share identical 16-pin DIP/SOIC pinouts per the "Functional Block Diagram and Pin Configuration" section, with matching IN1–IN4, S1–S4, D1–D4, V+, V−, GND, and VL assignments. The datasheet confirms identical pin numbering and function mapping across DG411HSDJ, DG411HSDY, and DG411HSDN packages - enabling drop-in replacement in existing SOIC footprints without layout changes.
