Product details
Overview
DG412LDY-E3 from Vishay Siliconix is a precision monolithic quad SPST low-voltage CMOS analog switch with break-before-make switching action, 17 Ω typical RDS(on), 19 ns tON, and ±3 V to ±6 V dual supply or 2.7 V to 12 V single supply operation - used in precision data acquisition signal routing where low distortion and high off-isolation are critical.
For engineers reviewing the DG412LDY-E3 datasheet, DG412LDY-E3 pinout, DG412LDY-E3 application, or DG412LDY-E3 equivalent, key selection considerations include guaranteed 17 Ω on-resistance at 12 V, 12 ns tOFF, TTL/CMOS compatibility, 0.25 nA leakage, and 2000 V ESD protection - all validated for -40 °C to +85 °C industrial temperature range in 16-pin narrow SOIC package.
Technical Context
The DG412LDY-E3 implements complementary control logic versus DG411L (IN = 0 → ON; IN = 1 → OFF), enabling direct interface with inverted digital control signals without external inverters. Its BiCMOS process ensures flat RDS(on) over full analog signal range and minimal charge injection (5 pC).
It supports rail-to-rail analog signal switching up to 12 V (single supply) or ±5 V (dual supply), with guaranteed off-isolation of -50 dB at 50 MHz and crosstalk suppression of -95 dB - critical for high-fidelity audio/video multiplexing and test equipment channel isolation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| RDS(on) | 17 Ω typical at V+ = 12 V - enables low insertion loss & minimal signal attenuation in precision analog paths |
| tON/tOFF | 19 ns / 12 ns - supports high-speed multiplexing in automated test equipment and real-time DAQ systems |
| Analog Signal Range | 0 to 12 V (single) or ±5 V (dual) - allows full-rail signal handling without clamping in battery-powered or mixed-supply systems |
| Leakage Current | 0.25 nA max - preserves accuracy in high-impedance sensor front-ends and microamp-level measurement circuits |
| ESD Protection | 2000 V HBM - provides robust handling during PCB assembly and field deployment without external protection |
| Supply Range | 2.7–12 V single or ±3–±6 V dual - simplifies power architecture across portable, industrial, and telecom applications |
Pinout & Package
Package: 16-pin narrow SOIC (JEDEC MS-012), body width 3.9 mm, pitch 1.27 mm, RoHS-compliant matte tin lead finish (E3 suffix).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | IN1–IN4 | Digital control inputs - active-low logic: INx = 0 V → switch ON; INx = 2.4 V → switch OFF |
| 2, 6, 10, 14 | S1–S4 | Switch source terminals - connect to analog signal sources (e.g., sensor outputs, DACs) |
| 3, 7, 11, 15 | D1–D4 | Switch drain terminals - route switched signals to ADC inputs, amplifiers, or transmission lines |
| 4 | V+ | Positive analog supply - must be ≥ VANALOG max; sets upper rail for analog signal range |
| 8 | V- | Negative analog supply - required for dual supply; sets lower rail (0 V for single supply) |
| 12 | GND | Analog ground reference - separate from digital ground; critical for noise rejection in mixed-signal systems |
| 16 | VL | Logic supply - powers internal level shifters; must match control logic voltage (e.g., 3.3 V or 5 V) |
Key Features
| Feature | Design Value |
|---|---|
| Break-before-make switching | Prevents momentary shorting between channels during state transitions - essential for fault-tolerant multiplexer designs |
| Flat RDS(on) vs. signal voltage | ±5 Ω variation over full 0–12 V range - maintains consistent gain and linearity in precision instrumentation |
| Low charge injection (5 pC) | Minimizes voltage glitches at ADC inputs during switching - reduces need for settling delay in sampling systems |
| TTL/CMOS-compatible inputs | Accepts standard 0.8 V / 2.4 V logic thresholds - eliminates level-shifting circuitry when interfacing with microcontrollers or FPGAs |
| High off-isolation (-50 dB @ 50 MHz) | Blocks crosstalk between inactive channels - enables clean multi-channel signal routing in RF-adjacent environments |

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 (65 ns), no break-before-make guarantee | Less suitable for high-speed precision DAQ; better for general-purpose switching with higher supply tolerance (up to ±20 V) | Select MAX4612ESE+ only if wider supply range is required and speed/leakage trade-offs are acceptable |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω typ), higher supply current (200 µA), requires external logic level translation for 3.3 V control | Better for ultra-low-loss paths but increases BOM count and layout complexity in low-power systems | Choose ADG1412BRUZ only when sub-2 Ω on-resistance justifies added cost and power overhead |
Compared with MAX4612ESE+ and ADG1412BRUZ, DG412LDY-E3 delivers optimal balance of speed (19 ns), precision (17 Ω, 0.25 nA), and ease of use (TTL/CMOS compatible, integrated level shift) in industrial-grade SOIC packaging - making it ideal for cost-sensitive, high-reliability embedded DAQ and telecom signal routing.

FAQ
What is the maximum analog signal voltage supported by DG412LDY-E3?
DG412LDY-E3 supports analog signals from 0 V to 12 V with single 12 V supply, or from -5 V to +5 V with ±5 V dual supply. Absolute maximum ratings allow V+ to V- up to 13 V, but guaranteed analog range is limited to the supply rails - exceeding these ranges risks clamping by internal diodes and potential damage if forward current exceeds 30 mA.
Does DG412LDY-E3 require a separate logic supply voltage?
Yes, DG412LDY-E3 requires VL pin (Pin 16) to be connected to the same voltage as the control logic driving IN1–IN4 (e.g., 3.3 V or 5 V). This powers internal level shifters, enabling TTL/CMOS compatibility across varying analog supply conditions - VL must be within (GND − 0.3 V) to (V+ + 0.3 V) per datasheet limits.
How does DG412LDY-E3 differ from DG411LDY-E3 in control logic?
DG412LDY-E3 uses inverted control logic versus DG411LDY-E3: for DG412LDY-E3, INx = 0 V turns the switch ON and INx = 2.4 V turns it OFF; DG411LDY-E3 operates oppositely. Both share identical pinout, RDS(on), timing, and electrical specs - the logic polarity difference allows direct replacement where control signal polarity matches the selected device.
Is DG412LDY-E3 pin-compatible with the legacy DG412?
Yes, DG412LDY-E3 is pin-for-pin compatible with the industry-standard DG412, as confirmed in the Vishay datasheet (Document 71397, Rev. F). It retains identical SOIC-16 footprint, pin functions, and electrical interface - while improving RDS(on), leakage, and ESD rating over the original part.
What is the thermal derating behavior of DG412LDY-E3 in SOIC package?
In its 16-pin narrow SOIC package, DG412LDY-E3 has a power dissipation limit of 650 mW at 25 °C, derating linearly at 7 mW/°C above 75 °C. At 105 °C ambient, maximum allowable power drops to 440 mW - design must ensure junction temperature stays below 150 °C under worst-case load and ambient conditions.
