Product details
Overview
DG411LEDY-T1-GE3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in instrumentation and medical 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.
For engineers reviewing the DG411LEDY-T1-GE3 datasheet, DG411LEDY-T1-GE3 pinout, DG411LEDY-T1-GE3 application, or DG411LEDY-T1-GE3 equivalent, key selection criteria include guaranteed low on-resistance across voltage ranges, fast 16 ns turn-on time, TTL/CMOS-compatible logic inputs, and SOIC-16 packaging for industrial PCB layouts.
Technical Context
The DG411LEDY-T1-GE3 implements four independent bidirectional analog switches with complementary logic control-low input enables conduction. Its monolithic silicon design supports rail-to-rail analog signal handling up to supply rails, with symmetrical conduction in both directions when enabled and blocking capability up to ±18 V absolute maximum ratings.
It features integrated level-shifting drive circuitry referenced to VL (logic supply), enabling compatibility with 3 V, 5 V, or 12 V logic while operating analog paths at higher voltages. Charge injection is minimized via matched transistor geometry and internal compensation, critical for data acquisition sample-and-hold integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 16 Ω typical at 12 V supply - ensures minimal signal attenuation and voltage drop in precision analog paths |
| Channel-on capacitance | 15 pF - limits high-frequency signal degradation and crosstalk in multi-channel routing |
| Charge injection | 6.6 pC - maintains accuracy in sampled-data systems by minimizing voltage glitch at switch transitions |
| Turn-on time | 16 ns - enables high-speed multiplexing in automated test equipment and real-time signal switching |
| Analog signal range | 0 to 12 V (single supply) or ±5 V (dual supply) - supports full-rail operation without clipping in sensor interfaces |
| Logic compatibility | TTL/CMOS - allows direct interfacing with microcontrollers and FPGAs without level-shifting circuitry |
| Supply range | 3–16 V single or ±3–±8 V dual - provides flexibility across battery-powered and line-powered embedded systems |
Pinout & Package
Package: 16-pin SOIC (narrow body, 3.9 mm width), RoHS-compliant, lead (Pb)-free, JEDEC MS-012 compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 (IN1–IN4) | Digital control inputs | Active-low logic inputs controlling respective NC switches; 0.8 V max low, 2.4 V min high thresholds |
| 5, 6, 12, 13 (S1–S4) | Source terminals | Analog inputs/outputs for NC switches; bidirectional, rail-to-rail capable |
| 7, 8, 11, 10 (D1–D4) | Drain terminals | Analog outputs/inputs connected to common node when switch is closed (NC configuration) |
| 9 (GND) | Analog ground reference | Return path for analog signals and substrate bias; must be low-impedance for leakage control |
| 14 (V−) | Negative supply rail | Required for dual-supply operation; sets lower bound of analog signal range |
| 15 (V+) | Positive supply rail | Sets upper bound of analog signal range; supports up to +18 V absolute max |
| 16 (VL) | Logic supply reference | Defines logic threshold levels; typically tied to V+ if ≤5 V, or to 5 V if V+ >5 V |
Key Features
| Feature | Design Value |
|---|---|

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 |
|---|---|---|---|
| MAX4617ESE+ | Higher on-resistance (35 Ω typ), 5 V-only logic supply, SOIC-16 package | Optimized for 5 V systems only; lacks ±3 V dual-supply support | Select when system uses fixed 5 V logic and analog rails; verify RDS(on) impact on signal chain accuracy |
| ADG1411BRZ | Lower on-resistance (1.8 Ω typ), but requires ≥9 V supply for full 12 V analog swing; SOIC-16 | Superior performance in high-precision, high-voltage applications; not suitable for 3 V operation | Choose for low-distortion audio or precision DAC output switching where supply headroom permits |
Compared with MAX4617ESE+ and ADG1411BRZ, DG411LEDY-T1-GE3 uniquely balances wide supply flexibility (3–16 V), low leakage (<10 nA), and moderate on-resistance (16 Ω) in a cost-effective SOIC package-making it optimal for general-purpose industrial and portable instrumentation where voltage scalability and reliability are prioritized over ultra-low RDS(on).

FAQ
What is the maximum analog signal voltage supported by DG411LEDY-T1-GE3?
DG411LEDY-T1-GE3 supports analog signals from 0 V to V+ (up to +12 V typical) in single-supply mode, or ±5 V in dual-supply mode. Absolute maximum ratings allow V+ to V− up to +18 V, but functional analog range is limited by supply rails - e.g., with V+ = 12 V and V− = 0 V, the usable analog range is 0–12 V.
Does DG411LEDY-T1-GE3 require a separate logic supply (VL) when using 3.3 V microcontroller I/O?
Yes - DG411LEDY-T1-GE3 requires VL to be connected to the logic source voltage (e.g., 3.3 V) to establish correct input thresholds. The datasheet specifies VL = V+ if V+ ≤ 5 V, so for 3.3 V operation, tie VL to the same 3.3 V rail driving IN1–IN4. This ensures proper 0.4 V low / 2.0 V high logic recognition.
How does the normally closed (NC) configuration of DG411LEDY-T1-GE3 affect its use in fail-safe signal paths?
DG411LEDY-T1-GE3 defaults to closed (conductive) when logic inputs are low (0 V), making it inherently fail-safe for applications where signal continuity is critical during power loss or controller reset. To open all switches, apply logic high (≥2.4 V) to IN1–IN4 - ensuring predictable default state without external pull-ups or auxiliary circuitry.
Can DG411LEDY-T1-GE3 operate reliably at −40 °C ambient temperature?
Yes - DG411LEDY-T1-GE3 is rated for operation from −40 °C to +85 °C (D suffix). All key parameters including RDS(on), leakage, and switching times are specified across this full range. At −40 °C, RDS(on) increases to ≤40 Ω (vs. 16 Ω typ at 25 °C), and tON extends to ≤70 ns, remaining well within functional requirements for most instrumentation applications.
Is DG411LEDY-T1-GE3 pin-compatible with DG412LEDY-T1-GE3?
Yes - DG411LEDY-T1-GE3 and DG412LEDY-T1-GE3 share identical SOIC-16 pinouts and package dimensions. They differ only in logic polarity: DG411LE turns ON with logic low (IN = 0 V), while DG412LE turns ON with logic high (IN = 2.4 V). No PCB redesign is needed when substituting between them - only firmware or control logic inversion is required.
