Product details
Overview
DG611DY-E3 from Vishay Siliconix is a high-speed, low-glitch quad SPST analog switch IC with 12 ns turn-on time, 18 Ω on-resistance, and ±2 pC charge injection, designed for fast sample-and-hold and pixel-rate video switching in precision signal routing applications.
For engineers reviewing the DG611DY-E3 datasheet, DG611DY-E3 pinout, DG611DY-E3 application, or DG611DY-E3 equivalent, key selection criteria include its 500 MHz bandwidth, dual-supply operation (V+ = 5–21 V, V− = −10 to 0 V), CMOS-compatible logic inputs (VIH ≥ 4 V, VIL ≤ 1 V), and SOIC-16 package compatibility with industrial temperature range (−40 °C to +85 °C).
Technical Context
The DG611DY-E3 implements four independent SPST switches using Vishay's proprietary D/CMOS process, integrating n-channel DMOS FETs with low-power CMOS control logic and epitaxial latchup protection. Each switch conducts bidirectionally when on and blocks up to 16 Vp-p when off.
Its logic polarity is active-low: INx = 0 V enables switch conduction (ON), while INx = 5 V disables it (OFF). The device supports single- or split-supply operation, with analog signal range spanning V− to (V+ − 5) V under recommended conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Turn-On Time | 12 ns - enables sub-100 MHz sampling without aperture uncertainty degradation |
| On-Resistance | 18 Ω typical - minimizes insertion loss and signal distortion in 50 Ω systems |
| Charge Injection | ±2 pC - reduces step error in sample-and-hold circuits to <1 mV with 1 nF hold capacitor |
| Bandwidth | 500 MHz - supports pixel-rate video switching up to 1080p60 without attenuation |
| Off Isolation | 74 dB at 5 MHz - suppresses crosstalk between adjacent channels in multi-source routing |
| Supply Range | V+ = 5–21 V, V− = −10 to 0 V - allows flexible biasing for bipolar analog signal handling |
| Logic Compatibility | 5 V CMOS - interfaces directly with standard microcontroller GPIO without level-shifting |
Pinout & Package
DG611DY-E3 is housed in a 16-pin narrow SOIC package (JEDEC MS-012, 3.9 mm width), with 1.27 mm pitch and RoHS-compliant matte tin terminations (E3 suffix). Thermal derating is 6 mW/°C above +75 °C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | Active-low logic: 0 V = ON, ≥4 V = OFF per switch |
| S1–S4 | Source terminal | Bidirectional analog path input/output; connects to signal source |
| D1–D4 | Drain terminal | Bidirectional analog path input/output; connects to load or next stage |
| V+ | Positive supply | Bias for high-side DMOS switches; sets upper analog voltage limit |
| V− | Negative supply | Bias for low-side DMOS switches; sets lower analog voltage limit |
| GND | Analog ground reference | Return path for leakage currents and substrate bias |
| VL | Logic supply | Provides CMOS threshold reference; must be ≥4 V and ≤V+ |
Key Features
| Feature | Design Value |
|---|---|

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 (2.7–12 V); 15 Ω RDS(on); 25 ns tON; no V− pin | Limited to unipolar signal routing; unsuitable for ±5 V video or bipolar sensor interfaces | Select when cost-sensitive unipolar systems require lower on-resistance and board space is constrained |
| ADG1419BRUZ | 12 V max supply; 1.3 Ω RDS(on); 20 ns tON; requires external logic level translation for 5 V CMOS | Higher drive strength but narrower voltage range; incompatible with 15 V/−3 V split supplies | Select for low-distortion instrumentation where ultra-low on-resistance outweighs supply flexibility |
Compared with MAX4617ESE+ and ADG1419BRUZ, the DG611DY-E3 uniquely supports wide-range split-supply operation (V+ up to 21 V, V− down to −10 V) and delivers faster switching (12 ns) without external level shifters-critical for legacy industrial and broadcast video designs requiring robust bipolar signal handling.

FAQ
What is the maximum analog signal voltage range supported by the DG611DY-E3?
The DG611DY-E3 supports an analog signal range from V− to (V+ − 5) V under recommended operating conditions. With V+ = 15 V and V− = −3 V, this yields a usable range of −3 V to +10 V. Absolute maximum ratings allow VS/VD to swing from (V− − 0.3 V) to (V+ + 16 V), but sustained operation beyond the recommended range risks increased leakage and distortion. Always verify signal levels against the DG611DY-E3 specification table for your specific V+/V− configuration.
Does the DG611DY-E3 require external pull-up or pull-down resistors on its INx pins?
No, the DG611DY-E3 does not require external pull-up or pull-down resistors on IN1–IN4. Its CMOS-compatible inputs have guaranteed thresholds (VIL ≤ 1 V, VIH ≥ 4 V) and draw only ±1 µA max input current across temperature. Direct connection to 5 V microcontroller GPIO or FPGA outputs is fully supported. However, if driving from open-drain or high-impedance sources, external biasing may be needed to ensure valid logic levels-always confirm with actual signal waveforms in the target DG611DY-E3 application.
Can the DG611DY-E3 operate with a single 5 V supply?
Yes, the DG611DY-E3 can operate with a single 5 V supply: configure V+ = 5 V, V− = GND, and VL = 5 V. In this mode, the analog signal range is limited to 0 V to +2 V (since VANALOG = V− to (V+ − 5) V), and RDS(on) increases to ~25 Ω. For full 0–5 V signal handling, use V+ = 10 V, V− = 0 V, VL = 5 V. The DG611DY-E3 datasheet specifies unipolar performance separately-verify tON, leakage, and bandwidth values in the "Specifications for Unipolar Supplies" table for your exact configuration.
What is the thermal resistance (θJA) of the DG611DY-E3 in SOIC-16 package?
The DG611DY-E3 in narrow SOIC-16 has a junction-to-ambient thermal resistance (θJA) of 125 °C/W, derived from its 600 mW maximum power dissipation rating and 75 °C derating threshold (6 mW/°C above 75 °C). This value assumes standard JEDEC 2-layer PCB mounting with 1 in² copper pour. Actual θJA improves with enhanced copper area or thermal vias. For continuous operation at 85 °C ambient, maximum allowable power dissipation is 540 mW-well above typical DG611DY-E3 consumption (<10 µW quiescent, <1 mW dynamic).
How does the DG611DY-E3 compare to the DG612DY-E3 in terms of logic polarity?
The DG611DY-E3 and DG612DY-E3 are functionally identical except for logic polarity: DG611DY-E3 turns switches ON when INx = 0 V (active-low), while DG612DY-E3 turns them ON when INx = 5 V (active-high). 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 logic architecture; no redesign is needed beyond inverting control signals when substituting DG611DY-E3 for DG612DY-E3 or vice versa.
