Product details
Overview
DG411LDQ-T1-E3 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 turn-on time, ±3 V to ±6 V dual-supply or 2.7 V to 12 V single-supply operation, and 2000 V ESD protection - used in precision audio routing and battery-powered data acquisition systems.
For engineers reviewing the DG411LDQ-T1-E3 datasheet, DG411LDQ-T1-E3 pinout, DG411LDQ-T1-E3 application, or DG411LDQ-T1-E3 equivalent, key selection considerations include its break-before-make timing (critical for glitch-free signal switching), flat on-resistance over full analog range, TTL/CMOS-compatible control logic, low 0.25 nA leakage, and TSSOP-16 RoHS-compliant packaging for high-density PCB layouts.
Technical Context
The DG411LDQ-T1-E3 implements BiCMOS fabrication to support both single- and dual-supply operation while maintaining low distortion and minimal charge injection (5 pC). Its channel architecture enforces strict break-before-make switching to prevent momentary shorting between signal paths during state transitions.
Control inputs accept standard TTL/CMOS voltage thresholds (logic "0" ≤ 0.8 V, logic "1" ≥ 2.4 V) referenced to VL, enabling direct interfacing with microcontrollers and FPGAs without level-shifting. Analog signal range spans 0–12 V (single supply) or ±5 V (dual supply), with guaranteed off-isolation of –50 dB at 50 MHz and crosstalk suppression exceeding –95 dB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 17 Ω typical - ensures minimal signal attenuation and thermal drift in precision analog paths |
| tON/tOFF | 19 ns / 12 ns - enables high-speed multiplexing in sampling systems up to ~25 MHz |
| Analog Range | 0–12 V (single) or ±5 V (dual) - supports rail-to-rail signal handling in mixed-signal front-ends |
| Leakage Current | 0.25 nA max - preserves accuracy in high-impedance sensor interfaces and integrator circuits |
| ESD Rating | 2000 V HBM - provides robust handling during board assembly and field deployment |
| Supply Range | 2.7–12 V single or ±3–±6 V dual - allows flexible power architecture in portable and industrial designs |
| Charge Injection | 5 pC - limits voltage glitch on sampled nodes, critical for ADC input conditioning |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MS-012 compatible), 4.4 mm × 5.0 mm footprint, 0.65 mm pitch, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 (IN1–IN4) | Digital control input | Active-high logic; drives corresponding switch ON when ≥2.4 V (TTL/CMOS compatible) |
| 2, 6, 10, 14 (S1–S4) | Source terminal | Input analog node for each SPST switch; connects to load when switch is closed |
| 3, 7, 11, 15 (D1–D4) | Drain terminal | Output analog node; routed to Sx when switch is ON |
| 4 (V+) | Positive supply | Bias for internal circuitry and analog channel conduction; sets upper analog rail |
| 8 (V−) | Negative supply | Required for dual-supply operation; sets lower analog rail (0 V for single supply) |
| 12 (GND) | Ground reference | Common return for digital logic and substrate bias; must be low-impedance |
| 16 (VL) | Logic supply | Independent 2.7–5.5 V rail for control inputs; decouples logic noise from analog path |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make timing | Guaranteed 6 ns minimum delay prevents signal shorting during transition - essential for fault-tolerant multiplexers |
| Flat RDS(on) profile | ≤5 Ω variation across full analog range - maintains consistent gain and linearity in audio/video paths |
| Low charge injection | 5 pC typical - avoids step errors in sample-and-hold and switched-capacitor circuits |
| High off-isolation | –50 dB at 50 MHz - suppresses crosstalk in multi-channel RF and communication front-ends |
| TTL/CMOS compatibility | Logic thresholds fixed at ≤0.8 V (low) and ≥2.4 V (high) - eliminates need for external level shifters |

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), no dual-supply support | Limited to single-supply 3–5 V systems; unsuitable for ±5 V audio or wide-range data acquisition | Prefer DG411LDQ-T1-E3 when dual-supply operation or sub-20 ns switching is required |
| ADG1411BRUZ | Lower RDS(on) (1.8 Ω typ), higher supply current (200 µA), requires external logic level translation for 3.3 V control | Better for ultra-low-loss instrumentation but increases BOM count and layout complexity | Select DG411LDQ-T1-E3 for cost-sensitive, low-power, and logic-compatible designs without added components |

FAQ
What supply configurations does the DG411LDQ-T1-E3 support?
The DG411LDQ-T1-E3 operates from a single supply of 2.7 V to 12 V (V− = GND) or dual supplies of ±3 V to ±6 V (V+ and V− referenced to GND). The logic supply VL accepts 2.7 V to 5.5 V independently, allowing clean separation between analog and digital domains. This flexibility makes DG411LDQ-T1-E3 suitable for both portable and industrial systems without redesigning power architecture.
Is the DG411LDQ-T1-E3 pin-compatible with the legacy DG411 series?
Yes, the DG411LDQ-T1-E3 is pin-for-pin compatible with the industry-standard DG411 and offers improved performance including lower RDS(on), faster switching, and enhanced ESD protection. It retains identical pinout, package dimensions, and functional block diagram - enabling drop-in replacement in existing SOIC or TSSOP-16 layouts without PCB modification.
What is the maximum analog signal frequency supported by the DG411LDQ-T1-E3?
The DG411LDQ-T1-E3 exhibits –3 dB bandwidth of 280 MHz under single-supply 12 V conditions, verified via insertion loss testing. At 50 MHz, it delivers –50 dB off-isolation and –95 dB crosstalk, confirming suitability for high-frequency analog routing in SDSL, video switching, and RF test equipment where signal integrity is critical.
Does the DG411LDQ-T1-E3 require external pull-up or pull-down resistors on control inputs?
No, the DG411LDQ-T1-E3 features TTL/CMOS-compatible inputs with defined thresholds (logic "0" ≤ 0.8 V, logic "1" ≥ 2.4 V) and input leakage <1 µA. Control lines can be driven directly from microcontroller GPIOs or FPGA outputs without external biasing - simplifying design and reducing component count in DG411LDQ-T1-E3-based systems.
How does the break-before-make timing function in the DG411LDQ-T1-E3?
The DG411LDQ-T1-E3 guarantees a minimum 6 ns break-before-make delay between switch transitions, preventing momentary short-circuits during state changes. This timing is internally controlled and independent of external RC networks, ensuring reliable glitch-free operation in multiplexer and relay-replacement applications where signal path integrity is mandatory.
