Product details
Overview
DG412LDY-T1-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch with break-before-make switching action, 17 Ω on-resistance (RDS(on)), 19 ns turn-on time (tON), 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 DG412LDY-T1-E3 datasheet, DG412LDY-T1-E3 pinout, DG412LDY-T1-E3 application, or DG412LDY-T1-E3 equivalent, key selection considerations include its complementary logic control relative to DG411L, guaranteed 0.25 nA off-leakage at 25 °C, 2000 V HBM ESD rating, and SOIC-16 package compatibility with industrial-grade temperature range (-40 °C to +85 °C).
Technical Context
The DG412LDY-T1-E3 implements four independent normally-open analog switches with inverted control logic versus DG411L (logic "0" = ON, logic "1" = OFF), enabling complementary channel pairing in multiplexer or relay-replacement designs. Its BiCMOS process ensures flat RDS(on) over full analog signal range and minimal charge injection (5 pC typical).
It supports rail-to-rail analog signal switching up to ±5 V (dual supply) or 0–12 V (single supply), with guaranteed off-isolation of -50 dB at 50 MHz and crosstalk suppression exceeding -95 dB - critical for high-fidelity signal integrity in mixed-signal test equipment and communication interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 17 Ω typical at V+ = 12 V, ensuring low insertion loss and minimal signal distortion in precision analog paths |
| tON / tOFF | 19 ns / 12 ns typical, enabling fast channel switching in high-speed data acquisition and video routing |
| Supply Range | 2.7–12 V single or ±3–±6 V dual, supporting direct integration into 3.3 V, 5 V, and ±5 V system rails |
| Off-Leakage Current | 0.25 nA typical at 25 °C, preserving accuracy in high-impedance sensor front-ends and precision DAC/ADC interfaces |
| ESD Rating | 2000 V HBM, providing robust handling margin during PCB assembly and field operation |
| Analog Signal Range | ±5 V (dual) or 0–12 V (single), allowing full-rail signal pass-through without clipping |
| Charge Injection | 5 pC typical, minimizing voltage glitches at switch transitions in sample-and-hold and multiplexed measurement circuits |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), body dimensions 9.9 mm × 3.9 mm × 1.5 mm, RoHS-compliant matte tin lead finish (E3 suffix), rated for -40 °C to +85 °C operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-low logic: INx = 0 V → corresponding switch ON; TTL/CMOS compatible thresholds (≤0.8 V low, ≥2.4 V high) |
| S1–S4 | Switch source terminals | Analog inputs for SPST channels; bidirectional signal path with symmetric RDS(on) |
| D1–D4 | Switch drain terminals | Analog outputs; electrically identical to Sx pins; support AC/DC-coupled signal routing |
| V+ | Positive supply | Accepts 2.7–12 V (single) or +3–+6 V (dual); powers analog switch core and level shifters |
| V- | Negative supply | Required for dual-supply operation (-3 to -6 V); sets lower analog rail boundary |
| GND | Ground reference | Logic ground and substrate reference; must be tied to system common for stable switching |
| VL | Logic supply | Separate 2.7–5.5 V rail for digital interface; decouples logic noise from analog performance |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents momentary shorting between channels during state transitions - essential for fault-tolerant multiplexing |
| Complementary logic vs. DG411L | Enables paired channel control without external inverters in differential or push-pull analog routing |
| Flat RDS(on) vs. signal voltage | ±5 Ω variation across full analog range, maintaining consistent gain and linearity in precision instrumentation |
| Low charge injection (5 pC) | Reduces settling error in high-resolution sampling systems, avoiding post-switching correction algorithms |
| 2000 V HBM ESD protection | Eliminates need for external transient suppressors in handheld or field-deployable test equipment |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESE+ | Higher RDS(on) (45 Ω typ), slower tON (40 ns), no VL pin - single-supply only | Less suitable for precision low-leakage or dual-supply systems; better for cost-sensitive 5 V-only designs | Select when VL decoupling is unnecessary and 12 V operation is not required |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω), higher supply voltage (up to ±15 V), but larger TSSOP-16 package and higher cost | Preferred for ultra-low-distortion RF/microwave switching; over-spec'd for general-purpose audio/data acquisition | Choose only when <2 Ω on-resistance and ±15 V capability justify premium pricing and layout impact |
Compared with DG412LDY-T1-E3, MAX4612ESE+ trades speed and leakage performance for lower cost in 5 V systems, while ADG1412BRUZ delivers superior conduction loss and voltage range at significantly higher unit price and board area - making DG412LDY-T1-E3 the optimal balance for industrial-grade precision analog switching at moderate speed and cost.

FAQ
What is the logic polarity of DG412LDY-T1-E3 control inputs?
The DG412LDY-T1-E3 uses active-low logic: applying logic "0" (≤0.8 V) to IN1–IN4 turns the corresponding switch ON, while logic "1" (≥2.4 V) turns it OFF. This is the inverse of DG411L, enabling complementary channel control without external inverters in multiplexer designs.
Does DG412LDY-T1-E3 support dual-supply operation?
Yes, DG412LDY-T1-E3 supports dual-supply operation from ±3 V to ±6 V. When using dual supplies, V+ connects to the positive rail, V- to the negative rail, GND to system ground, and VL to a separate 2.7–5.5 V logic supply - enabling true bipolar analog signal switching from -5 V to +5 V.
What is the maximum analog signal voltage range for DG412LDY-T1-E3?
Under dual-supply conditions (±5 V), DG412LDY-T1-E3 supports an analog signal range of -5 V to +5 V. Under single-supply conditions (12 V), the range is 0 V to 12 V. Signals exceeding these rails are clamped by internal diodes; forward current must be limited to 30 mA continuous per terminal.
Is DG412LDY-T1-E3 pin-compatible with the legacy DG412?
Yes, DG412LDY-T1-E3 is pin-for-pin compatible with the industry-standard DG412 and offers improved performance including lower RDS(on), faster switching, and enhanced ESD protection - allowing drop-in replacement in existing SOIC-16 layouts without PCB modification.
What package type does DG412LDY-T1-E3 use?
DG412LDY-T1-E3 uses a 16-pin narrow SOIC package (JEDEC MS-012), with body dimensions 9.9 mm × 3.9 mm × 1.5 mm, matte tin lead finish (RoHS-compliant E3 suffix), and thermal resistance θJA = 155 °C/W - suitable for reflow soldering and industrial temperature cycling.
