Product details
Overview
DG411LDY-T1-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch with 17 Ω on-resistance, 19 ns turn-on time, and ±3 V to ±6 V dual-supply or 2.7 V to 12 V single-supply operation. It delivers break-before-make switching for audio/video signal routing in battery-powered test equipment and data acquisition systems.
For engineers reviewing the DG411LDY-T1-E3 datasheet, DG411LDY-T1-E3 pinout, DG411LDY-T1-E3 application, or DG411LDY-T1-E3 equivalent, key selection criteria include guaranteed RDS(on) flatness over signal range, sub-1 pC charge injection at 3 V, 2000 V ESD protection, and SOIC-16 package compatibility with industrial temperature range (–40 °C to +85 °C).
Technical Context
The DG411LDY-T1-E3 implements BiCMOS process technology to support both single- and dual-supply configurations while maintaining low leakage (±10 nA max) and high off-isolation (71 dB at 1 MHz). Its control logic is active-high: INx = logic high enables corresponding Sx–Dx channel conduction.
Each of the four independent SPST switches features matched on-resistance (<5 Ω variation across analog range), minimal crosstalk (95 dB), and flat frequency response up to 280 MHz (–3 dB point). The device integrates internal ESD diodes clamping signals beyond V+ or V– rails, with forward current limited to 30 mA continuous per terminal.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 17 Ω typical at 12 V supply - ensures minimal signal attenuation and distortion in precision analog paths |
| Turn-on time | 19 ns typical - enables high-speed multiplexing in automated test equipment and communication interfaces |
| Turn-off time | 12 ns typical - supports fast channel switching without overlap in time-critical sampling systems |
| Charge injection | 5 pC typical - reduces voltage glitch on sampled nodes, critical for high-resolution ADC front-ends |
| Off-isolation | 71 dB at 1 MHz - suppresses crosstalk between inactive channels in multi-signal routing applications |
| ESD protection | 2000 V HBM - provides robust handling during PCB assembly and field operation without external protection |
| Supply range | 2.7–12 V single or ±3–±6 V dual - accommodates legacy 5 V, modern 3.3 V, and battery-backed 3 V systems |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012, 3.9 mm width), RoHS-compliant, rated for –40 °C to +85 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control input | Active-high logic: high voltage ≥2.4 V enables corresponding S–D path; compatible with TTL/CMOS levels |
| S1–S4 | Switch source | Analog input node for each SPST channel; clamped to V+ or V– via internal diodes if exceeded |
| D1–D4 | Switch drain | Analog output node; bidirectional conduction when enabled; same voltage range as Sx pins |
| V+ | Positive supply rail | Accepts 2.7–12 V (single) or +3–+6 V (dual); powers analog switch core and level-shifting circuitry |
| V− | Negative supply rail | Accepts 0 V (single) or –3––6 V (dual); required for bipolar signal handling and rail-to-rail operation |
| GND | Ground reference | Common return for digital logic and substrate bias; separate from analog signal ground in mixed-signal layouts |
| VL | Logic supply | Supplies 2.7–12 V to internal level shifter; decoupling recommended to minimize noise coupling into analog paths |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Guaranteed tD ≥6 ns prevents momentary shorting between channels during state transitions |
| Flat RDS(on) vs. signal voltage | ≤5 Ω variation across full analog range - maintains consistent gain and linearity in precision instrumentation |
| Low leakage current | ±10 nA max at 85 °C - preserves accuracy in high-impedance sensor interfaces and sample-hold circuits |
| High-frequency performance | –3 dB bandwidth of 280 MHz - supports video signal routing and broadband communication switching |
| TTL/CMOS compatibility | Input thresholds fixed at 0.8 V (low) and 2.4 V (high) - eliminates need for external level shifters in microcontroller-driven systems |

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); 25 Ω RDS(on); 25 ns tON; no dual-supply support | Limited to unipolar signal ranges; unsuitable for ±5 V precision instrumentation | Select when system uses only 3.3 V logic and analog rails, and dual-supply operation is unnecessary |
| ADG1412BRUZ | 4-channel, but SPDT configuration; 1.8 Ω RDS(on); 125 ns tON; requires external level shifting for 3 V logic | Provides normally-open/normally-closed functionality; slower switching limits high-speed T&M use | Select when break-before-make timing is less critical and ultra-low on-resistance justifies higher cost and layout complexity |
Compared with DG411LDY-T1-E3, MAX4617ESE+ offers lower cost but sacrifices dual-supply flexibility and speed, while ADG1412BRUZ delivers superior on-resistance at the expense of switching latency and control interface simplicity - making DG411LDY-T1-E3 optimal for balanced performance in portable, precision, and mixed-supply designs.

FAQ
What supply voltages does the DG411LDY-T1-E3 support?
The DG411LDY-T1-E3 supports single-supply operation from 2.7 V to 12 V and dual-supply operation from ±3 V to ±6 V. At 12 V single supply, it achieves 17 Ω typical RDS(on) and 19 ns tON; at ±5 V dual supply, RDS(on) is 20 Ω typical with 21 ns tON. The DG411LDY-T1-E3 must have V+ and V− referenced correctly - floating V− is not permitted.
Does the DG411LDY-T1-E3 require external pull-up or pull-down resistors on its INx pins?
No, the DG411LDY-T1-E3 does not require external pull-up or pull-down resistors on IN1–IN4. Its digital inputs are TTL/CMOS-compatible with defined thresholds (logic low ≤0.8 V, logic high ≥2.4 V) and draw only ±1 µA max input current. However, in noisy environments or when driving from open-drain sources, a 10 kΩ pull-up to VL is recommended to ensure reliable logic high assertion.
Can the DG411LDY-T1-E3 switch signals beyond its supply rails?
No, the DG411LDY-T1-E3 cannot reliably switch analog signals beyond its V+ or V− rails. Internal ESD diodes clamp Sx or Dx pins exceeding those rails, limiting forward current to 30 mA. Exceeding V+ or falling below V− risks latch-up or parametric shift. For rail-to-rail or overvoltage-tolerant switching, external clamping or a dedicated overvoltage-protected switch like the TMUX6208 is required.
What is the maximum signal frequency supported by the DG411LDY-T1-E3?
The DG411LDY-T1-E3 has a –3 dB bandwidth of 280 MHz under 12 V single-supply conditions with 50 Ω source/load. Insertion loss remains <0.5 dB up to 100 MHz, making it suitable for composite video, USB 1.1, and baseband SDSL signals. Performance degrades at lower supplies: at 3 V, –3 dB bandwidth drops to ~100 MHz due to increased RDS(on) and reduced drive strength.
Is the DG411LDY-T1-E3 pin-compatible with the legacy DG411?
Yes, the DG411LDY-T1-E3 is pin-for-pin compatible with the industry-standard DG411 in SOIC-16 packaging. It retains identical pinout, footprint, and logic polarity (INx high = ON), while improving RDS(on), switching speed, and ESD rating. No PCB redesign is needed when upgrading from DG411 to DG411LDY-T1-E3, though layout review for improved decoupling near VL and V+ is recommended.
