Product details
Overview
DG611EEQ-T1-GE3 from Vishay Siliconix is a quad SPST analog switch with normally closed (NC) configuration, designed for precision signal routing in high-speed, low-distortion applications. It delivers 72 Ω typical on-resistance at ±5 V dual supply, 1.4 pC charge injection, 3 pF off-capacitance, and 1 GHz 3 dB bandwidth - enabling use in medical instrumentation front-ends and automated test equipment multiplexing stages.
For engineers reviewing the DG611EEQ-T1-GE3 datasheet, DG611EEQ-T1-GE3 pinout, DG611EEQ-T1-GE3 application, or DG611EEQ-T1-GE3 equivalent, key selection criteria include rail-to-rail analog signal handling, -40 °C to +125 °C operation, TSSOP-16 package compatibility, and guaranteed 2 V logic-high threshold at +5 V supply.
Technical Context
The DG611EEQ-T1-GE3 implements four independent CMOS transmission gate switches with complementary control logic: logic low enables conduction (NC), logic high disconnects. It supports single-supply (3–16 V) and dual-supply (±3 V to ±8 V) operation, with full specification at +3 V, +5 V, and ±5 V.
All channels exhibit matched on-resistance (ΔRDS(on) ≤ 2.5 Ω), low flatness variation (Rflat(on) ≤ 20 Ω), and symmetrical bidirectional signal flow. Dynamic performance includes 23 ns turn-on / 14 ns turn-off times and -59 dB off-isolation at 10 MHz - critical for multi-channel data acquisition integrity.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Switch Type | Quad SPST, normally closed (NC) - all four switches conduct when control input is logic low |
| On-Resistance (RDS(on)) | 72 Ω typ. at ±5 V - ensures minimal signal attenuation and gain error in precision analog paths |
| Charge Injection | 1.4 pC typ. - limits voltage glitch in sample-and-hold and switched-capacitor circuits |
| Bandwidth | 1 GHz 3 dB - supports high-fidelity routing of RF and fast digital signals up to ~300 Mbps |
| Leakage Current | <0.1 nA max. at 85 °C - preserves accuracy in high-impedance sensor interfaces and integrators |
| Supply Range | 3 V to 16 V single or ±3 V to ±8 V dual - enables direct interfacing with legacy ±5 V systems and modern 3.3 V logic |
| Logic Threshold | 2 V min. high-level input at +5 V - ensures robust TTL/CMOS compatibility without level-shifting |
Pinout & Package
Package: 16-pin TSSOP (JEDEC MO-153, 4.4 mm × 5.0 mm × 1.2 mm), lead-free and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN1–IN4 | Digital control inputs | Active-low enables NC switch conduction; compatible with 2 V logic-high threshold at +5 V supply |
| S1–S4 | Source terminals | Analog inputs for each SPST switch; rail-to-rail capable from V− to V+ |
| D1–D4 | Drain terminals | Analog outputs; bidirectional conduction identical to source side |
| V+ | Positive supply | Accepts 3–16 V single or +3 to +8 V dual supply; powers internal switch core and level shifters |
| V− | Negative supply | Accepts 0 V (ground) or −3 to −8 V; enables true bipolar signal handling |
| GND | Ground reference | Logic ground return; separate from analog signal path to minimize noise coupling |
| NC | No-connect | Pin 3 is internally unused; must be left unconnected per datasheet |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ADG1411BRUZ | Quad SPST NO, 1.8 Ω RDS(on), ±15 V supply, SOIC-16 - lower on-resistance but higher charge injection (12 pC) | Better for low-RON power switching; unsuitable for precision sample-and-hold due to higher glitch energy | Select DG611EEQ-T1-GE3 when charge injection & bandwidth dominate; ADG1411BRUZ when ultra-low RON is critical |
| MAX4617ESE+ | Quad SPST NC, 60 Ω RDS(on), +5 V only, SOIC-16 - narrower supply range, no dual-supply support | Limited to single-rail 5 V systems; lacks rail-to-rail analog range and -40 °C to +125 °C rating | DG611EEQ-T1-GE3 preferred for industrial/multi-supply designs; MAX4617ESE+ acceptable only in cost-sensitive 5 V-only apps |
Compared with ADG1411BRUZ and MAX4617ESE+, the DG611EEQ-T1-GE3 uniquely balances ultra-low charge injection (1.4 pC), 1 GHz bandwidth, and full dual-supply operation - making it the only option among the three qualified for precision bipolar signal routing across extended temperature ranges.

FAQ
What is the maximum operating temperature range for the DG611EEQ-T1-GE3?
The DG611EEQ-T1-GE3 is fully specified from -40 °C to +125 °C, with electrical parameters validated across this full industrial temperature range. This includes on-resistance, leakage current, charge injection, and switching speed - ensuring reliable operation in under-hood automotive and factory-floor environments where ambient temperatures exceed 85 °C.
Does the DG611EEQ-T1-GE3 support dual-supply operation, and what are the limits?
Yes, the DG611EEQ-T1-GE3 supports dual-supply operation from ±3 V to ±8 V. Absolute maximum ratings allow V+ to V− differential up to +18 V, and individual supply pins tolerate -0.3 V to +18 V relative to GND. It is fully characterized at ±5 V, delivering 72 Ω RDS(on), 23 ns tON, and 1.4 pC charge injection under those conditions.
How does the DG611EEQ-T1-GE3 handle analog signals exceeding the supply rails?
The DG611EEQ-T1-GE3 includes internal clamping diodes on all S and D pins. Signals exceeding V+ or V− are clamped, but forward diode current must be limited to the device's maximum current ratings (30 mA continuous, 100 mA pulsed). External series resistors are recommended to protect against overvoltage transients beyond the clamp capability.
Is the DG611EEQ-T1-GE3 pin-compatible with earlier DG611 variants like the DG611A?
No - the DG611EEQ-T1-GE3 is not pin-compatible with the legacy DG611A. While both are quad NC SPST switches in TSSOP-16, the DG611EEQ-T1-GE3 features updated internal architecture, tighter specifications (e.g., 1.4 pC vs. 3 pC charge injection), and revised absolute maximum ratings. PCB layout reuse requires verification of pin function mapping and thermal pad requirements.
What is the logic behavior of the DG611EEQ-T1-GE3 control inputs?
The DG611EEQ-T1-GE3 has active-low logic: a logic low (≤0.8 V at +5 V supply) turns the switch ON (conducting), and a logic high (≥2 V at +5 V supply) turns it OFF (open). Input thresholds scale with supply voltage - e.g., at +3 V supply, logic high is ≥1.4 V - ensuring robust operation across its full 3–16 V single-supply range.
