Product details
Overview
DG411LDY-T1 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch configured as four independent normally-open switches, with 17 Ω typical RDS(on), 19 ns tON, 12 ns tOFF, and ±3 V to ±6 V dual-supply or 2.7 V to 12 V single-supply operation - used in precision audio/video signal routing and battery-powered data acquisition systems.
For engineers reviewing the DG411LDY-T1 datasheet, DG411LDY-T1 pinout, DG411LDY-T1 application, or DG411LDY-T1 equivalent, key selection considerations include break-before-make timing (DG413L only), leakage <15 nA at full temperature range, flat on-resistance over signal range, ESD rating of 2000 V, and SOIC-16 package compatibility with standard PCB layouts.
Technical Context
The DG411LDY-T1 implements BiCMOS process technology to support both single- and dual-supply operation while maintaining low distortion and high off-isolation (71 dB at 1 MHz). Its control logic follows DG411L truth table: logic low (≤0.8 V) enables all four switches; logic high (≥2.4 V) disables them.
Each channel features matched source/drain terminals, internal clamping diodes limiting analog signals to V+ or V−, and charge injection of only 5 pC - enabling accurate sampling in precision ADC front-ends and low-glitch switching in audio paths without external buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 17 Ω typical at V+ = 12 V - ensures minimal signal attenuation and thermal drift in DC-coupled sensor interfaces |
| tON/tOFF | 19 ns / 12 ns - supports high-speed multiplexing up to ~25 MHz without significant edge degradation |
| Analog Range | 0 to 12 V (single supply) or ±5 V (dual supply) - covers full dynamic range of industrial sensors and line-level audio |
| Leakage Current | ±15 nA max at full temperature - preserves accuracy in high-impedance transducer conditioning circuits |
| ESD Rating | 2000 V HBM - allows direct handling and board-level integration without additional protection circuitry |
| Charge Injection | 5 pC - limits voltage step error in sample-and-hold stages and prevents audible clicks in audio switching |
| Off-Isolation | 71 dB at 1 MHz - suppresses crosstalk between adjacent channels in multi-channel ATE systems |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), 3.9 mm × 9.9 mm body, 1.27 mm pitch, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-low logic: ≤0.8 V enables corresponding switch; TTL/CMOS compatible with 5 V logic rails |
| 5, 6, 12, 13 (S1–S4) | Switch source terminals | Common analog input nodes; internally connected to D1–D4 when enabled |
| 7, 8, 11, 10 (D1–D4) | Switch drain terminals | Output/analog signal path nodes; isolated from Sx when switch is OFF |
| 9 (V−) | Negative supply rail | Required for dual-supply operation; tied to GND in single-supply mode |
| 14 (V+) | Positive supply rail | Supports 2.7–12 V; powers analog channel and internal level shifters |
| 15 (GND) | Analog/digital ground reference | Common return for supplies and logic; must be low-impedance for noise immunity |
| 16 (VL) | Logic supply reference | Accepts 3–5 V to set input threshold; decouples logic interface from analog supply noise |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make | Not implemented - DG411LDY-T1 uses simultaneous ON/OFF control per channel, avoiding signal shorting during transition |
| Flat RDS(on) | ±5 Ω variation across full analog signal range - maintains consistent gain and THD in AC-coupled video paths |
| Low charge injection | 5 pC - enables sub-12-bit settling in 1 MSPS data acquisition without external reset circuitry |
| TTL/CMOS compatibility | Valid input thresholds (0.8 V low / 2.4 V high) at VL = 5 V - eliminates need for level translators with microcontroller GPIOs |
| High off-isolation | 71 dB at 1 MHz - isolates RF-sensitive analog inputs from digital control lines in mixed-signal PCBs |

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 (2.7–5.5 V); 35 Ω RDS(on); 125 ns tON; no dual-supply support | Suitable for 3.3 V embedded systems but not ±5 V instrumentation | Select when cost sensitivity outweighs speed and dual-rail flexibility |
| ADG1411BRUZ | Higher performance: 1.8 Ω RDS(on), 10 ns tON, ±15 V rating; 16-lead TSSOP only | Enables higher-precision, higher-voltage applications but requires layout change | Select when ultra-low on-resistance and faster switching justify TSSOP rework |
Compared with MAX4617ESE+ and ADG1411BRUZ, the DG411LDY-T1 uniquely balances dual-supply operation, 17 Ω on-resistance, and SOIC-16 footprint - making it optimal for legacy-compatible upgrades in test equipment and audio gear where ±5 V rails and board space are fixed constraints.

FAQ
What supply configurations does the DG411LDY-T1 support?
The DG411LDY-T1 supports both single-supply (2.7 V to 12 V, with V− tied to GND) and dual-supply (±3 V to ±6 V) operation. The VL pin accepts 3 V to 5 V logic supply independently, allowing clean separation between analog and digital domains. This flexibility makes DG411LDY-T1 suitable for mixed-signal systems where analog rails differ from logic voltage levels.
Does the DG411LDY-T1 have break-before-make switching behavior?
No, the DG411LDY-T1 does not implement break-before-make switching. It is a quad SPST device with independent control per channel, and all switches transition simultaneously. Break-before-make timing is specified only for the DG413L variant, which integrates two NO and two NC switches. For DG411LDY-T1, ensure external sequencing if signal shorting during transition must be avoided.
What is the maximum analog signal voltage range for DG411LDY-T1 at ±5 V supplies?
At ±5 V dual-supply operation, the DG411LDY-T1 supports an analog signal range of –5 V to +5 V. This is confirmed in the datasheet's "Analog Signal Range" specification under ±5 V test conditions (page 4). Signals exceeding these limits will be clamped by internal diodes, so external protection is required for overvoltage transients beyond ±5.5 V.
How does the DG411LDY-T1 compare to the legacy DG411 in terms of performance?
The DG411LDY-T1 is a low-voltage optimized, pin-for-pin compatible upgrade to the industry-standard DG411. It improves on-resistance (17 Ω vs. 35 Ω typical), reduces switching time (19 ns vs. 100 ns tON), adds 2000 V ESD protection, and extends supply range down to 2.7 V. These enhancements make DG411LDY-T1 preferable for modern low-power, high-fidelity designs without requiring PCB redesign.
Is the DG411LDY-T1 RoHS compliant?
Yes, the DG411LDY-T1 is RoHS compliant. The datasheet explicitly states "RoHS COMPLIANT" on page 2 and confirms Pb-free terminations for the DY suffix (SOIC package). The "* Pb containing terminations are not RoHS compliant, exemptions may apply" note applies only to non-RoHS variants - DG411LDY-T1 carries the standard RoHS-compliant finish.
