Product details
Overview
DG611DY-T1 from Vishay Siliconix is a high-speed, low-glitch quad SPST analog switch IC designed for precision signal routing in fast-switching systems. It features 12 ns turn-on time, 18 Ω on-resistance, ±2 pC charge injection, 500 MHz bandwidth, and operates from ±3 V to ±10.5 V dual supplies or 5–21 V single supply. It is used in pixel-rate video switching and DAC deglitching where minimal transient error and wide analog bandwidth are critical.
For engineers reviewing the DG611DY-T1 datasheet, DG611DY-T1 pinout, DG611DY-T1 application, or DG611DY-T1 equivalent, key selection criteria include guaranteed 12 ns tON, sub-2 pC charge injection, 4-channel independent control with logic-compatible inputs (VIL ≤ 1 V, VIH ≥ 4 V), and SOIC-16 package compatibility with standard PCB footprints.
Technical Context
The DG611DY-T1 implements four independent n-channel DMOS analog switches fabricated using Vishay's proprietary D/CMOS process, combining low-power CMOS control logic with high-speed lateral DMOS FETs. Each switch conducts bidirectionally with matched on-resistance and blocks up to 16 Vp-p when off.
It uses an epitaxial layer to prevent latch-up and integrates level translators to ensure proper switching across logic supply (VL) from 4 V to V+. Input thresholds are fixed at ≤1 V for logic "0" and ≥4 V for logic "1", enabling direct interface with 5 V CMOS systems without external biasing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| tON | 12 ns - Enables sub-100 MHz sample rates in fast data acquisition without aperture uncertainty degradation. |
| RDS(on) | 18 Ω typical - Minimizes insertion loss and signal distortion in 50 Ω or 75 Ω video/audio paths. |
| Charge injection | ±2 pC - Reduces step-induced offset errors in sample-and-hold and switched-capacitor circuits. |
| Bandwidth | 500 MHz - Supports full-spectrum integrity for HD video, RF sampling, and high-frequency test equipment signals. |
| Off isolation | 74 dB at 5 MHz - Ensures channel crosstalk remains below -70 dB in multi-source video mixing applications. |
| Analog range | V– to (V+ – 5) V - Allows rail-to-rail analog signal handling with 5 V headroom margin for safe overvoltage clamping. |
| Supply range | V+: 5–21 V; V–: –10 to 0 V - Supports flexible bipolar operation (e.g., ±5 V, ±12 V) or single-ended 12 V/15 V systems. |
Pinout & Package
Package: 16-pin narrow-body SOIC (JEDEC MS-012), 3.9 mm × 9.9 mm body, 1.27 mm pitch, RoHS-compliant (Pb-free terminations).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-high logic inputs; drive internal level translators to enable corresponding SPST switch (logic "1" = ON). |
| 5, 6, 13, 14 (S1–S4) | Switch source terminals | Analog input nodes; bidirectional conduction path when switch is ON; connect to signal sources or common points. |
| 7, 8, 11, 12 (D1–D4) | Switch drain terminals | Analog output nodes; mirror S-terminal behavior; support symmetric signal routing in video or instrumentation paths. |
| 9 (V–) | Negative supply rail | Bias reference for NMOS switch channel; must be ≤ 0 V and ≥ (V+ – 21 V) per absolute max ratings. |
| 10 (V+) | Positive supply rail | Primary power for DMOS switches; sets upper analog voltage limit and influences RDS(on) and bandwidth. |
| 15 (GND) | Analog/digital ground reference | Common return for V–, logic drivers, and substrate; requires low-impedance PCB connection to minimize noise coupling. |
| 16 (VL) | Logic supply voltage | Independent 4–V+ supply for CMOS control logic; decouples digital noise from analog signal paths. |
Key Features
| Feature | Design Value |
|---|---|
| Four independent SPST switches | Enables discrete routing of four separate analog signals (e.g., RGB+sync, I/Q pairs, multi-channel ADC inputs) without shared control constraints. |
| Low charge injection (±2 pC) | Reduces hold-step error to <1 mV in 1 nF sample-and-hold capacitors, eliminating need for post-switching correction circuitry. |
| 5 V CMOS logic compatibility | Eliminates level-shifting components when interfacing with microcontrollers, FPGAs, or ASICs operating at 5 V TTL/CMOS logic levels. |
| Wide analog bandwidth (500 MHz) | Maintains <0.1 dB flatness up to 100 MHz and supports composite video (NTSC/PAL), HDMI auxiliary channels, and IF sampling. |
| Single-supply or split-supply operation | Supports design reuse across 12 V industrial systems and ±5 V test equipment without board redesign or BOM changes. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | Higher RDS(on) (35 Ω typ), slower tON (25 ns), lower bandwidth (300 MHz), but offers fault protection and higher ESD rating (±4 kV HBM). | Better suited for industrial sensor interfaces with surge exposure; less ideal for >50 MHz video or sub-20 ns timing-critical sampling. | Select MAX4617ESE+ when robustness in harsh environments outweighs speed requirements. |
| ADG1414BRUZ | Lower RDS(on) (1.3 Ω typ), faster tON (10 ns), but requires higher logic supply (VL = 2.7–5.5 V) and lacks independent VL pin for noise isolation. | Preferred for ultra-low-loss instrumentation amplifier multiplexing; not optimal for mixed-signal systems needing isolated logic/analog grounds. | Choose ADG1414BRUZ when minimizing on-resistance dominates over layout-level noise separation needs. |
Compared with DG611DY-T1, MAX4617ESE+ trades speed for ruggedness and ADG1414BRUZ sacrifices logic supply flexibility for lower resistance-making DG611DY-T1 the balanced choice for high-fidelity video, fast sampling, and mixed-voltage system integration where independent VL and 500 MHz bandwidth are essential.

FAQ
What is the maximum analog signal voltage range supported by the DG611DY-T1?
The DG611DY-T1 supports an analog signal range from V– to (V+ – 5) V under recommended operating conditions. For example, with V+ = 15 V and V– = –3 V, the usable analog range is –3 V to +10 V. This 13 V span ensures compatibility with standard ±5 V and ±12 V systems while maintaining 5 V headroom for internal clamp diode safety margins. The DG611DY-T1 datasheet specifies this range explicitly in the Recommended Operating Range table.
Does the DG611DY-T1 require separate logic and analog ground connections?
No-the DG611DY-T1 uses a single GND pin (Pin 15) for both logic and analog return paths. However, best practice is to tie this pin to a low-impedance analog ground plane and isolate digital noise sources via PCB layout. The device's independent VL pin (Pin 16) enables logic supply decoupling, reducing coupling into analog paths. This architecture avoids mandatory split-ground schemes while still supporting noise-sensitive designs when implemented correctly in the DG611DY-T1 layout.
Can the DG611DY-T1 operate with a single 12 V supply?
Yes-the DG611DY-T1 supports single-supply operation with V+ = 12 V and V– = 0 V (GND). In this configuration, the analog signal range becomes 0 V to +7 V (since VANALOG = V– to (V+ – 5)). Logic inputs remain compatible with 5 V CMOS levels, and VL can be tied to 5 V. This mode is validated in the datasheet's Unipolar Supplies section and is commonly used in portable video gear and industrial controllers where negative rails are unavailable.
How does the DG611DY-T1 compare to the DG612DY-T1 in functionality?
The DG611DY-T1 and DG612DY-T1 are functionally identical quad SPST switches except for inverted logic polarity: DG611DY-T1 turns ON with logic HIGH (≥4 V) and OFF with logic LOW (≤1 V), whereas DG612DY-T1 operates inversely. Both share identical electrical specs-including 12 ns tON, 18 Ω RDS(on), and 500 MHz bandwidth-and use the same SOIC-16 package. The choice depends solely on system-level control signal polarity, not performance or pinout.
Is the DG611DY-T1 RoHS compliant?
Yes-the DG611DY-T1 is RoHS compliant with lead-free terminations, as confirmed in the Vishay ordering information table and package drawings (Document #71261). The "-T1" suffix denotes tape-and-reel packaging for automated assembly, and all variants listed under DG611DY-T1 and DG611DY-T1-E3 meet EU RoHS Directive 2011/65/EU requirements. Compliance documentation is available through Vishay's quality portal using the DG611DY-T1 part number.
