Product details
Overview
DG1411EEN-T1-GE4 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in ±15 V, ±5 V, and +12 V dual/single-supply systems. It delivers 1.5 Ω on-resistance, 70 ns turn-on time, rail-to-rail analog signal handling, and operates across –40 °C to +125 °C - ideal for medical instrumentation and automated test equipment where low distortion and break-before-make switching are critical.
For engineers reviewing the DG1411EEN-T1-GE4 datasheet, DG1411EEN-T1-GE4 pinout, DG1411EEN-T1-GE4 application, or DG1411EEN-T1-GE4 equivalent, key selection criteria include verified NC logic behavior, QFN-16 (4 mm × 4 mm) package thermal performance (θJA = 32 °C/W), guaranteed channel matching (ΔRDS(on) ≤ 0.24 Ω), and compatibility with 0.8 V / 2 V TTL/CMOS logic thresholds without VL supply.
Technical Context
The DG1411EEN-T1-GE4 implements four independent CMOS-based SPST switches fabricated on a precision low-parasitic process. Its normally closed architecture ensures continuity at logic low (IN = 0 V), with guaranteed break-before-make timing (tOPEN ≥ 10 ns at ±15 V) preventing transient shorting during state transitions.
It supports true dual-supply operation (±4.5 V to ±16.5 V) or single-supply mode (4.5 V to 24 V), with rail-to-rail analog signal range (VANALOG = V− to V+), low charge injection (–41 pC), and minimal off-capacitance (CS(OFF) = 24 pF) - enabling high-fidelity signal integrity in data acquisition and A/V switching applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 1.5 Ω typical at ±15 V - ensures low insertion loss and minimal voltage drop in precision analog paths |
| On-resistance flatness | 0.2 Ω typical - maintains linearity over full signal swing, reducing harmonic distortion |
| Channel matching | 0.04 Ω typical ΔRDS(on) - enables accurate differential or ratiometric measurements |
| Switching time | 70 ns tON, 50 ns tOFF at ±15 V - supports high-speed multiplexing up to ~1 MHz bandwidth |
| Supply range | ±4.5 V to ±16.5 V dual or 4.5 V to 24 V single - simplifies system power architecture with no VL rail required |
| Logic thresholds | VINH = 2 V min., VINL = 0.8 V max. - ensures robust interfacing with 3 V and 5 V microcontrollers |
| Charge injection | –41 pC - minimizes settling error in sample-and-hold and ADC front-end circuits |
Pinout & Package
Package: QFN-16 (4 mm × 4 mm), exposed pad tied to V−, RoHS-compliant and halogen-free.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 12, 11, 10, 4, 9, 5, 6, 7, 8, 16, 15, 14, 13 | Standard I/O mapping per functional diagram | Pin numbering follows QFN-16 top-view layout: V− (Pin 1), V+ (Pin 2), S4 (Pin 3), GND (Pin 4), S3 (Pin 5), N.C. (Pin 6), S1 (Pin 7), S2 (Pin 8), D1 (Pin 9), IN1 (Pin 10), IN2 (Pin 11), D2 (Pin 12), D4 (Pin 13), IN4 (Pin 14), IN3 (Pin 15), D3 (Pin 16) |

| V+ (Pin 2) | Positive supply rail | Accepts up to +25 V; absolute max rating defines safe operating window |
| GND (Pin 4) | Analog/digital reference ground | Common return for digital inputs and analog signal paths; separate from power ground recommended |
| S1–S4 (Pins 3,5,7,8) | Source terminals of SPST switches | Connected internally to load side; NC configuration means closed when IN = 0 V |
| D1–D4 (Pins 9,12,13,16) | Drain terminals of SPST switches | Connected to signal source; bidirectional conduction supported up to supply rails |
| IN1–IN4 (Pins 10,11,14,15) | Digital control inputs | Active-low logic: switch closes when input ≤ 0.8 V; no pull-up/pull-down required |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) logic | Ensures default signal path continuity during power-up or controller reset - critical for fail-safe sensor monitoring |
| Rail-to-rail analog range | Supports full-scale signal switching from V− to V+ without clipping, preserving dynamic range in ±15 V instrumentation |
| Low on-resistance flatness (0.2 Ω) | Maintains consistent gain and phase response across input voltage - essential for audio and precision measurement |
| Break-before-make timing | Guaranteed minimum 10 ns isolation between switch states prevents momentary shorts in multi-channel routing |
| No VL logic supply required | Reduces BOM count and layout complexity by eliminating auxiliary voltage rail for level translation |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Pin-compatible TSSOP-16; identical NC function but higher RDS(on) (1.8 Ω typ.); 130 °C/W θJA | Lower thermal performance limits continuous current in high-density layouts | Select for legacy TSSOP footprint compatibility where board space allows larger thermal footprint |
| TMUX1308PWR | Single-supply only (1.8–5.5 V); 3.5 Ω RDS(on); no dual-supply capability; smaller 1.6 mm × 2.1 mm WQFN | Not suitable for ±15 V or rail-to-rail analog signals beyond 5.5 V | Choose only for low-voltage, cost-sensitive consumer applications - not a functional replacement for DG1411EEN-T1-GE4 |
Compared with ADG1411BRUZ and TMUX1308PWR, DG1411EEN-T1-GE4 uniquely combines NC logic, ±15 V dual-supply operation, 1.5 Ω on-resistance, and QFN-16 thermal efficiency (32 °C/W), making it the only option qualified for high-precision, wide-supply industrial and medical signal routing.

FAQ
What is the logic behavior of DG1411EEN-T1-GE4?
DG1411EEN-T1-GE4 is a normally closed (NC) quad SPST switch: each switch conducts when its corresponding digital input (IN1–IN4) is logic low (≤ 0.8 V), and opens when logic high (≥ 2 V). This behavior is confirmed in the truth table and functional block diagram for DG1411E in the official Vishay datasheet (Rev. E, May 2025).
Does DG1411EEN-T1-GE4 require a separate VL logic supply?
No, DG1411EEN-T1-GE4 does not require a VL supply. Its digital inputs accept standard 0.8 V / 2 V TTL/CMOS thresholds directly from 3 V or 5 V controllers, eliminating the need for level-shifting circuitry or auxiliary rails - a confirmed feature in the "Digital Control" section of the Vishay datasheet.
What is the maximum continuous switch current rating for DG1411EEN-T1-GE4?
At TA = 25 °C, the QFN-16 package supports 250 mA maximum continuous switch current; at TA = 125 °C, this derates to 100 mA. These values are specified in the Absolute Maximum Ratings table and reflect thermal limits of the 4 mm × 4 mm QFN package (θJA = 32 °C/W).
Can DG1411EEN-T1-GE4 operate from a single +12 V supply?
Yes, DG1411EEN-T1-GE4 supports single-supply operation from +4.5 V to +24 V. At +12 V, it delivers 2.5 Ω typical on-resistance and 150 MHz bandwidth, with verified performance across –40 °C to +125 °C - documented in the "Electrical Characteristics – Single 12 V Supply" section of the datasheet.
Is the exposed pad on the QFN-16 package of DG1411EEN-T1-GE4 electrically connected?
Yes, the exposed thermal pad on DG1411EEN-T1-GE4's QFN-16 package is electrically tied to V−, as explicitly noted in the "Functional Block Diagram and Pin Configuration" section. Proper PCB connection of this pad to the V− plane is required for both thermal performance and electrical stability.
