Product details
Overview
DG201HSDY from Vishay Siliconix is a high-speed quad SPST CMOS analog switch designed for precision signal routing in data acquisition and sample-and-hold circuits. It delivers 38 ns turn-on time, 25 Ω on-resistance (±15 V dual supply), <100 pA off-leakage, and TTL/CMOS logic compatibility - enabling fast, low-error switching of bipolar analog signals up to ±15 V in automated test equipment.
For engineers reviewing the DG201HSDY datasheet, DG201HSDY pinout, DG201HSDY application, or DG201HSDY equivalent, key selection criteria include guaranteed 38 ns tON at ±15 V, matched rDS(on) ≤3%, 85 dB off-isolation at 100 kHz, and TSSOP-16 packaging with validated RoHS-compliant terminations.
Technical Context
The DG201HSDY integrates four independent bidirectional analog switches fabricated on a proprietary high-voltage silicon-gate process with epitaxial latchup protection. Each channel supports symmetrical conduction and blocks input voltages up to the supply rails (V+ to V− = 44 V max).
It operates from dual supplies (±15 V typical) or single supply (10.8–16.5 V), with logic thresholds fixed at VINH ≥2.4 V and VINL ≤0.8 V. Charge injection is specified at −5 pC (dual supply) and 10 pC (single supply), directly impacting pedestal error in integrator and chopper applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tON | 38 ns (typical, RL = 1 kΩ, CL = 35 pF, ±15 V supply) - enables sub-25 MHz sampling in high-throughput DAQ systems |
| rDS(on) | 25 Ω (max 50 Ω over temp, ±15 V) - minimizes gain error and THD in precision signal paths |
| IS(off) | ±1 nA (max, ±15.5 V off-state) - ensures <0.001% leakage-induced drift in 16-bit sample-and-hold hold capacitors |
| OIRR | 85 dB (at 100 kHz, RL = 1 kΩ) - suppresses crosstalk between adjacent channels in multi-channel multiplexing |
| Q (Charge Injection) | −5 pC (dual supply, VS = 0 V) - limits pedestal error to <50 µV on 1 nF hold capacitors |
| V+ to V− Range | 44 V (absolute max) - supports rail-to-rail analog signal switching across industrial ±15 V and ±12 V systems |
| Package | TSSOP-16 (4.4 mm × 5.0 mm, 0.65 mm pitch) - enables high-density PCB layouts in space-constrained ATE and avionics modules |
Pinout & Package
Package: 16-pin Thin Shrink Small Outline Package (TSSOP), RoHS-compliant, moisture sensitivity level 1 (MSL-1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | IN1–IN4 | Digital control inputs; TTL/CMOS-compatible; drive internal switch gates |
| 2, 6, 10, 14 | S1–S4 | Source terminals; bidirectional analog signal entry points for each switch |
| 3, 7, 11, 15 | D1–D4 | Drain terminals; bidirectional analog signal exit points; electrically symmetric to Sx |
| 4 | V+ | Positive analog supply rail; must be ≥ |V−| and ≤ (V− + 44 V) |
| 8 | GND | Digital ground reference; tied to substrate; separate from analog return in mixed-signal layouts |
| 12 | V− | Negative analog supply rail; enables true bipolar signal handling down to −15 V |
| 16 | NC | No connect; internally unconnected; must remain floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| High-Speed Switching | 38 ns tON and 30 ns tOFF1 at ±15 V - reduces aperture uncertainty in 20+ MSPS data acquisition |
| Bipolar Signal Support | Full analog range from V− to V+ (e.g., −15 V to +15 V) - eliminates level-shifting circuitry in ±12 V instrumentation front-ends |
| Low On-Resistance Match | ≤3% rDS(on) matching between channels - critical for gain-switching accuracy and chopper offset cancellation |
| Ultra-Low Leakage | ±1 nA max IS(off) at 125 °C - preserves charge integrity on 10 nF hold capacitors for >100 ms hold times |
| Robust Latchup Immunity | Epitaxial isolation layer - prevents destructive latchup under transient overvoltage or ESD events in hi-rel systems |
Applications
| Data Acquisition Systems | Sample-and-Hold Circuits |

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 |
|---|---|---|---|
| ADG201HS | Identical pinout and function but higher rDS(on) (35 Ω typ vs. 25 Ω) and slower tON (50 ns); not RoHS-compliant | Limited to legacy industrial designs requiring backward compatibility with obsolete ADI footprints | Select only if replacing existing ADG201HS stock; DG201HSDY offers 20% faster switching and RoHS compliance |
| HI201HS | Same package and logic interface but wider rDS(on) spread (25–100 Ω) and no guaranteed charge injection spec | Suitable for non-critical signal routing where pedestal error <1 mV is acceptable | Prefer DG201HSDY when charge injection <10 pC or rDS(on) matching <5% is required for precision hold circuits |
Compared with ADG201HS and HI201HS, the DG201HSDY provides tighter rDS(on) matching (≤3%), lower charge injection (−5 pC), and documented RoHS compliance - making it the preferred choice for new designs demanding 16-bit+ accuracy in data acquisition and avionics.

FAQ
What is the maximum supply voltage range supported by the DG201HSDY?
The DG201HSDY supports a maximum V+ to V− differential of 44 V. Under dual-supply operation, it is typically used with ±15 V rails (30 V total), and under single-supply mode, it operates from 10.8 V to 16.5 V referenced to GND. Exceeding these limits risks permanent damage per Absolute Maximum Ratings.
Does the DG201HSDY support bidirectional analog signal flow?
Yes, the DG201HSDY supports fully bidirectional analog signal flow on all four channels. When ON, Sx and Dx terminals conduct equally in either direction; when OFF, they block analog signals up to the supply rails (V+ and V−), enabling flexible signal routing in both source-to-drain and drain-to-source configurations.
What is the guaranteed charge injection specification for DG201HSDY?
The DG201HSDY guarantees −5 pC charge injection (typical) under dual-supply conditions (V+ = +15 V, V− = −15 V, VS = 0 V, CL = 1 nF). This value is measured and specified in the datasheet and directly determines pedestal error magnitude in sample-and-hold and integrator reset applications.
Is the DG201HSDY RoHS-compliant and lead-free?
Yes, the DG201HSDY-T1-E3 variant is RoHS-compliant with lead-free terminations. The "E3" suffix explicitly denotes Pb-free, halogen-free, and RoHS-compliant construction per Vishay's documentation (S-71241–Rev. G), and it is rated MSL-1 for moisture sensitivity.
How does the DG201HSDY differ from the DG201HSDJ (DIP package) version?
The DG201HSDY uses a TSSOP-16 package (4.4 mm × 5.0 mm), while DG201HSDJ uses a 16-pin plastic DIP. Electrically, both share identical specifications, pinout, and functionality. The DG201HSDY is optimized for high-density PCBs and automated assembly, whereas DG201HSDJ suits prototyping and through-hole legacy systems.
