Product details
Overview
DG441LDY-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch in 16-pin narrow SOIC package, featuring 17 Ω on-resistance, 20 ns turn-on time, and ±3 V to ±6 V dual-supply or 2.7 V to 12 V single-supply operation. It serves as a high-fidelity signal routing device in precision data acquisition and audio/video switching systems.
For engineers reviewing the DG441LDY-E3 datasheet, DG441LDY-E3 pinout, DG441LDY-E3 application, or DG441LDY-E3 equivalent, key selection criteria include guaranteed RDS(on) flatness over signal range, break-before-make switching action, 2000 V ESD protection, and TTL/CMOS logic compatibility across temperature.
Technical Context
The DG441LDY-E3 implements four independent single-pole single-throw (SPST) switches using BiCMOS wafer fabrication, enabling simultaneous low on-resistance and fast switching. Its control logic is inverted relative to DG442L: logic "0" enables conduction, logic "1" disables.
It supports rail-to-rail analog signal handling (0–12 V single supply or ±5 V dual supply), with guaranteed channel-to-channel crosstalk of –95 dB and off-isolation of –71 dB at 1 MHz - critical for high-fidelity multiplexing in test equipment and communication interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 17 Ω typical at 12 V supply - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Turn-on time | 20 ns typical - enables high-speed multiplexing in automated test equipment sampling at >10 MSPS |
| Analog signal range | 0 to 12 V (single supply) or ±5 V (dual supply) - supports full-rail signal routing without clipping |
| Off-isolation | –71 dB at 1 MHz - suppresses coupling between inactive channels in multi-signal systems |
| Charge injection | 5 pC typical - limits voltage glitch on sample-hold capacitors during switching transitions |
| ESD protection | 2000 V HBM - enhances robustness during board handling and system integration |
| Supply range | 2.7–12 V single or ±3–±6 V dual - compatible with battery-powered and industrial power rails |
Pinout & Package
Package: 16-pin narrow-body SOIC (JEDEC MS-012), 7.5 mm × 10.3 mm footprint, 1.27 mm pitch, 1.75 mm max height.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control input | Active-low logic: logic "0" ≤ 0.8 V enables corresponding switch; logic "1" ≥ 2.4 V disables |
| 5, 6, 12, 13 (S1–S4) | Source terminal | Analog input/output node for each SPST switch; bidirectional signal path |
| 7, 8, 11, 10 (D1–D4) | Drain terminal | Analog output/input node; paired with Sx to form closed switch path when enabled |
| 9 (GND) | Analog/digital ground reference | Common return for analog signals and digital logic; must be low-impedance |
| 14 (V−) | Negative supply rail | Required for dual-supply operation; connects to –3 V to –6 V or 0 V for single-supply use |
| 15 (V+) | Positive supply rail | Supplies internal bias and switch driver; accepts 2.7–12 V (single) or +3–+6 V (dual) |
| 16 (NC) | No connect | Internally unconnected; must remain floating or tied to GND per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents momentary shorting between channels during state transition - essential for fault-tolerant multiplexing |
| Flat RDS(on) vs. signal voltage | ≤5 Ω variation across full analog range - maintains consistent gain and linearity in programmable-gain amplifiers |
| TTL/CMOS-compatible inputs | Logic thresholds defined at 0.8 V (low) and 2.4 V (high) - eliminates need for level-shifting with microcontroller GPIOs |
| Low leakage current | ±1 nA max at room temperature - preserves charge integrity in high-impedance sample-and-hold circuits |
| Rail-to-rail signal handling | Supports analog signals from V− to V+ - enables direct interfacing with op-amp outputs and sensor front-ends |

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) (45 Ω typ), slower tON (40 ns), same SOIC-16 package | Lower bandwidth (–3 dB at ~100 MHz); less suitable for video or high-speed data acquisition | Select when cost sensitivity outweighs speed and on-resistance requirements |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω typ), higher supply voltage (up to ±15 V), TSSOP-16 package | Requires PCB redesign due to different footprint; superior for high-precision instrumentation needing sub-ohm resistance | Select when ultra-low on-resistance and wider supply range justify layout change |
Compared with MAX4617ESE+ and ADG1412BRUZ, the DG441LDY-E3 delivers optimal balance of speed (20 ns), on-resistance (17 Ω), and SOIC-16 compatibility - making it ideal for space-constrained, medium-bandwidth analog routing where pinout retention matters.

FAQ
What is the maximum analog signal voltage range supported by DG441LDY-E3?
The DG441LDY-E3 supports analog signals from V− to V+ across its full operating range: 0 to 12 V with single supply (V− = GND), or –5 V to +5 V with ±5 V dual supply. Absolute maximum ratings allow V+ to V− up to 13 V, but guaranteed performance is specified within the 12 V single-supply or ±6 V dual-supply limits. This rail-to-rail capability makes DG441LDY-E3 suitable for interfacing directly with op-amps and sensors without level-shifting.
Does DG441LDY-E3 require external pull-up or pull-down resistors on its digital inputs?
No, DG441LDY-E3 does not require external pull-up or pull-down resistors. Its digital inputs are TTL/CMOS-compatible with defined thresholds: logic "0" ≤ 0.8 V and logic "1" ≥ 2.4 V at V+ = 12 V. Input leakage remains below ±1.5 µA across temperature, ensuring reliable logic interpretation even with high-impedance drive sources. This simplifies interface design with microcontrollers and FPGAs in DG441LDY-E3-based systems.
How does the break-before-make behavior of DG441LDY-E3 improve system reliability?
The DG441LDY-E3 implements true break-before-make switching: each SPST channel fully disconnects before any other channel closes. This prevents momentary short-circuits between analog sources - critical in multiplexer configurations where mismatched voltages could cause current surges or latch-up. In DG441LDY-E3 applications like programmable-gain amplifiers or sensor arrays, this behavior eliminates cross-talk transients and protects downstream circuitry without requiring external timing control.
Can DG441LDY-E3 operate from a 3.3 V single supply?
Yes, DG441LDY-E3 is fully specified for 3.3 V single-supply operation. At V+ = 3.3 V (V− = 0 V), it guarantees RDS(on) ≤ 100 Ω, tON ≤ 175 ns, and logic compatibility with 3.3 V CMOS levels. The datasheet confirms functionality down to 2.7 V, making DG441LDY-E3 suitable for modern low-voltage embedded systems. Performance trade-offs versus 12 V operation (e.g., higher on-resistance) are explicitly characterized in the DG441LDY-E3 specification tables.
What is the thermal derating requirement for DG441LDY-E3 in SOIC package?
For the DG441LDY-E3 in 16-pin narrow SOIC package, power dissipation must be derated above 75 °C at 7.6 mW/°C. The device's rated power dissipation is 650 mW at 25 °C ambient, decreasing linearly to zero at approximately 158 °C. This derating applies regardless of supply configuration (single or dual) and must be accounted for in thermally constrained layouts. Thermal design guidance for DG441LDY-E3 is provided in Vishay's Application Note AN826.
