Product details
Overview
DG1411EEQ-T1-GE4 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, 1.5 Ω on-resistance at ±15 V, rail-to-rail signal handling up to ±15 V, and 70 ns turn-on time - designed for precision signal routing in medical instrumentation and automated test equipment.
For engineers reviewing the DG1411EEQ-T1-GE4 datasheet, DG1411EEQ-T1-GE4 pinout, DG1411EEQ-T1-GE4 application, or DG1411EEQ-T1-GE4 equivalent, key selection criteria include guaranteed break-before-make timing, low charge injection (−41 pC), on-resistance flatness (0.2 Ω), and TSSOP-16 package compatibility with industrial temperature range (−40 °C to +125 °C).
Technical Context
The DG1411EEQ-T1-GE4 implements four independent CMOS SPST switches with NC logic polarity (switches conduct when control input = 0 V), operates from single 4.5–24 V or dual ±4.5–±15 V supplies, and requires no separate VL logic supply due to integrated 0.8 V/2 V TTL/CMOS-compatible thresholds.
Its architecture delivers rail-to-rail analog conduction, low parasitic capacitance (CS(OFF) = 24 pF, CD(ON) = 87 pF), and low distortion via flat on-resistance over full signal range - enabling high-fidelity signal switching without external level-shifting or buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| On-resistance | 1.5 Ω typical at ±15 V - ensures minimal insertion loss and signal attenuation in precision analog paths |
| On-resistance flatness | 0.2 Ω max - maintains linearity and low THD (0.0039 %) across full ±15 V signal swing |
| Supply range | Single: 4.5–24 V; Dual: ±4.5–±15 V - supports flexible system-level power architecture |
| Turn-on time | 70 ns typical at ±15 V - enables fast multiplexing in data acquisition and ATE systems |
| Charge injection | −41 pC typical - minimizes voltage glitch in sample-and-hold and ADC front-end circuits |
| Off isolation | −78 dB typical at 100 kHz - provides strong channel-to-channel signal blocking in multi-channel systems |
| Operating temp. | −40 °C to +125 °C - qualified for industrial and automotive under-hood environments |
Pinout & Package
TSSOP-16 package (5.0 mm × 6.4 mm × 1.05 mm height), RoHS-compliant and halogen-free, with exposed pad not connected (N.C.) per functional diagram.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | IN1–IN4 digital control inputs | Active-low logic: logic 0 closes switch; compatible with 0.8 V/2 V TTL/CMOS thresholds |
| 5, 6, 13, 14 | S1–S4 source terminals | Analog inputs for NC switches; connect to signal sources requiring default continuity |
| 7, 8, 11, 12 | D1–D4 drain terminals | Analog outputs; conduct to Sx when INx = 0; block when INx = 1 |
| 9 | GND | Ground reference for digital logic and substrate bias |
| 10 | V+ | Positive supply rail (up to +24 V or +16.5 V in dual mode) |
| 15 | V− | Negative supply rail (down to −25 V or −16.5 V in dual mode) |
| 16 | N.C. | No internal connection; must be left floating or grounded per layout best practice |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (NC) configuration | Ensures fail-safe signal path continuity during power loss or control failure in safety-critical monitoring systems |
| Rail-to-rail analog operation | Supports full-supply-swing signals (V− to V+) without clipping - eliminates need for external clamping or level shifters |
| Break-before-make timing | Guaranteed 24 ns minimum tOPEN prevents momentary shorting between channels during switching |
| Low charge injection (−41 pC) | Reduces settling error in precision sampling circuits, enabling <1 LSB error in 16-bit+ data acquisition |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Same NC function, 1.8 Ω RDS(on) at ±15 V, 16-lead TSSOP, but requires VL logic supply | Higher on-resistance increases insertion loss; VL dependency adds board complexity | Select if ADI ecosystem integration or SPI-controlled variants are required; avoid if minimizing BOM count is critical |
| MAX4611ESE+ | NC configuration, 3.5 Ω RDS(on) at ±15 V, SO-16, no VL supply, but higher charge injection (±10 pC) | Lower bandwidth (80 MHz) and higher distortion limit use in >100 kSPS systems | Acceptable for cost-sensitive industrial controls where 16-bit precision is not required |
Compared with ADG1411BRUZ and MAX4611ESE+, the DG1411EEQ-T1-GE4 offers the lowest on-resistance and charge injection in TSSOP-16, making it optimal for high-accuracy, low-glitch signal routing where supply simplicity and thermal stability are prioritized.

FAQ
What is the maximum supply voltage rating for DG1411EEQ-T1-GE4?
The DG1411EEQ-T1-GE4 has an absolute maximum supply rating of ±16.5 V for dual supplies or 24 V for single supply. Exceeding these limits risks permanent damage. Its specified operating range is ±4.5 V to ±15 V dual or 4.5 V to 24 V single, with full parametric performance guaranteed within those bounds. The 35 V absolute max rating applies only to V+–V− differential stress, not individual rail limits.
Does DG1411EEQ-T1-GE4 require a separate logic supply voltage (VL)?
No, DG1411EEQ-T1-GE4 does not require a separate VL supply. It features integrated logic threshold circuitry with 0.8 V low-level and 2 V high-level input thresholds, enabling direct interface with standard 3 V or 5 V TTL/CMOS logic without level shifters. This simplifies power design and reduces component count compared to alternatives requiring dedicated VL rails.
How does the normally closed (NC) behavior of DG1411EEQ-T1-GE4 affect system safety?
The DG1411EEQ-T1-GE4's NC configuration ensures analog continuity (S–D path closed) when control inputs are de-asserted (logic 0) or unpowered. In safety-critical applications like patient monitoring, this guarantees default signal path integrity during power loss, reset, or firmware hang - preventing open-circuit faults that could disable vital signal acquisition before protective logic engages.
Can DG1411EEQ-T1-GE4 operate with a single +12 V supply?
Yes, DG1411EEQ-T1-GE4 supports single-supply operation from +4.5 V to +24 V. At +12 V, its on-resistance is 2.5 Ω typical (max 4.4 Ω), turn-on time is 150 ns typical, and analog signal range spans 0 V to +12 V. All digital inputs remain compatible with 0.8 V/2 V thresholds, and no modifications to control logic are needed - only V− is tied to GND instead of a negative rail.
What is the thermal resistance (θJA) of DG1411EEQ-T1-GE4 in TSSOP-16 package?
The DG1411EEQ-T1-GE4 in TSSOP-16 has a junction-to-ambient thermal resistance (θJA) of 130 °C/W under standard JEDEC PCB conditions (2s2p copper). This value assumes no thermal vias or heatsinking. For continuous 190 mA switch current at 25 °C ambient, junction temperature rise is ~25 °C - well within the 150 °C max rating. Derating is required above 85 °C ambient per the 90 mA max rating at 125 °C.
