Product details
Overview
DG412LEDY-T1-GE3 from Vishay Siliconix is a quad SPST analog switch with normally open (NO) configuration, designed for precision signal routing in low-voltage and mixed-supply systems. It delivers 16 Ω on-resistance, 15 pF channel-on capacitance, <8 pC charge injection, and operates from 3 V to 16 V single supply or ±3 V to ±8 V dual supply - enabling use in battery-powered medical instrumentation and automated test equipment.
For engineers reviewing the DG412LEDY-T1-GE3 datasheet, DG412LEDY-T1-GE3 pinout, DG412LEDY-T1-GE3 application, or DG412LEDY-T1-GE3 equivalent, key selection criteria include its logic-inverted control (IN high = switch off), guaranteed 50 ns max tON/tOFF, SOIC-16 package compatibility, and validated performance at 3 V, 5 V, and ±5 V supply conditions.
Technical Context
The DG412LEDY-T1-GE3 implements four independent NMOS/PMOS complementary transmission gates with integrated level-shifting circuitry, enabling TTL/CMOS-compatible digital inputs (VIL ≤ 0.8 V, VIH ≥ 2.4 V) to control analog signals spanning the full supply rails. Its architecture ensures symmetrical conduction in both directions when on and rail-to-rail blocking when off.
It supports single-supply operation down to 3 V with RDS(on) ≤ 90 Ω and dual-supply operation at ±5 V with RDS(on) ≤ 30 Ω, while maintaining sub-10 pC charge injection and >68 dB off-isolation at 1 MHz - critical for low-distortion data acquisition and audio switching.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω typical at +12 V single supply - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Channel-on capacitance | 15 pF - limits high-frequency signal coupling and preserves bandwidth in video/audio routing |
| Charge injection | 6.6 pC typical - reduces glitch-induced errors in sample-and-hold and multiplexed ADC front-ends |
| Turn-on/off time | 16 ns / 9 ns typical at +12 V - enables fast channel switching in high-throughput ATE systems |
| Analog signal range | 0 to +12 V (single supply) or ±5 V (dual supply) - supports full-rail signal handling without clipping |
| Logic compatibility | TTL/CMOS - interfaces directly with microcontrollers and FPGAs without level-shifting circuitry |
| Off-isolation | 68.4 dB at 1 MHz - suppresses crosstalk between adjacent channels in dense multiplexer designs |
Pinout & Package
Package: 16-pin SOIC (narrow body, 3.9 mm width), RoHS-compliant, lead (Pb)-free, tape-and-reel packaging (2500 units per reel).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | IN1–IN4 (digital control inputs) | Inverted logic: high voltage disables corresponding switch; compatible with 3.3 V/5 V logic families |
| 2, 6, 10, 14 | S1–S4 (switch sources) | Analog input terminals; bidirectional conduction path when enabled |
| 3, 7, 11, 15 | D1–D4 (switch drains) | Analog output terminals; connect to downstream signal chain or measurement node |
| 4 | V+ | Positive supply rail; supports 3–16 V single supply or +3 to +8 V in dual-supply mode |
| 8 | V− | Negative supply rail; required for dual-supply operation (±3 to ±8 V) or grounded for single supply |
| 12 | GND | Power ground reference; must be tied to system ground plane for stable operation |
| 16 | VL | Logic supply reference; typically tied to V+ for single supply or to 5 V for optimal noise immunity |
Key Features
| Feature | Design Value |
|---|---|
| Wide supply range support | Operates from 3 V to 16 V single supply or ±3 V to ±8 V dual supply - eliminates need for external regulators in portable and industrial systems |
| Low distortion switching | 16 Ω RDS(on) and 15 pF CD(on) ensure <0.1% gain error and >100 MHz –3 dB bandwidth in 50 Ω systems |
| Ultra-low charge injection | 6.6 pC typical minimizes voltage step errors in precision sampling circuits, reducing post-switching settling time |
| Fast, matched timing | 16 ns tON/9 ns tOFF with <5 ns skew between channels - enables synchronized multi-channel acquisition |
| Rail-to-rail analog capability | Full supply-range signal handling (e.g., 0–5 V or ±5 V) without external biasing - simplifies front-end design for sensors and DACs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad SPST analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4612ESE+ | Higher RDS(on) (35 Ω typ. at +5 V), slower tON (45 ns), same SOIC-16 footprint | Less suitable for low-distortion audio; acceptable for general-purpose industrial I/O | Select when cost sensitivity outweighs precision requirements and ±5 V dual-supply operation is not needed |
| ADG1412BRUZ | Lower RDS(on) (1.3 Ω typ.), higher supply voltage limit (+36 V), TSSOP-16 only | Over-specified for low-voltage portable gear; requires PCB redesign for TSSOP layout | Choose only if ultra-low on-resistance and high-voltage tolerance are mandatory, and board space allows TSSOP |
Compared with MAX4612ESE+ and ADG1412BRUZ, the DG412LEDY-T1-GE3 offers the optimal balance of low on-resistance (16 Ω), fast switching (16 ns), and SOIC-16 compatibility for cost-sensitive, battery-operated instrumentation where rail-to-rail 3–5 V analog routing is essential.

FAQ
What is the logic polarity of the DG412LEDY-T1-GE3 control inputs?
The DG412LEDY-T1-GE3 uses inverted logic: a logic high (≥2.4 V) on IN1–IN4 turns the corresponding switch OFF, while a logic low (≤0.8 V) turns it ON. This complements the DG411LE, which uses non-inverted logic, allowing direct substitution in existing layouts where control inversion is acceptable or programmable.
Can the DG412LEDY-T1-GE3 operate from a single 3 V supply?
Yes, the DG412LEDY-T1-GE3 is fully specified for 3 V single-supply operation, with RDS(on) ≤ 90 Ω, tON ≤ 85 ns, and leakage <10 nA over –40 °C to +85 °C. Its guaranteed functionality at 3 V makes it suitable for coin-cell or Li-ion powered portable diagnostics and handheld meters.
What is the maximum analog signal voltage the DG412LEDY-T1-GE3 can switch?
The DG412LEDY-T1-GE3 supports analog signals from 0 V to V+ in single-supply mode (e.g., 0–12 V), or from V− to V+ in dual-supply mode (e.g., –5 V to +5 V). Signals exceeding these rails are clamped by internal diodes; forward current must be limited to ≤30 mA per terminal to avoid damage.
Does the DG412LEDY-T1-GE3 require a separate logic supply (VL) pin?
Yes, VL must be connected - typically to V+ for single-supply operation or to a clean 5 V rail for improved noise immunity. Leaving VL floating or unconnected violates absolute maximum ratings and may cause erratic switching behavior or increased leakage in the DG412LEDY-T1-GE3.
How does the DG412LEDY-T1-GE3 compare to the DG412LEDQ-T1-GE3?
The DG412LEDY-T1-GE3 uses a 16-pin SOIC package (3.9 mm width), while DG412LEDQ-T1-GE3 uses a 16-pin TSSOP package (4.4 mm width). Both share identical electrical specifications, temperature range (–40 °C to +85 °C), and RoHS compliance. The choice depends solely on PCB layout constraints and assembly process compatibility.
