Product details
Overview
DG604EEQ-T1-GE3 from Vishay Siliconix is a 4-channel CMOS analog multiplexer designed for precision signal routing in data acquisition and sample-and-hold circuits. It operates from single supplies (3 V to 16 V) or dual supplies (±3 V to ±8 V), delivers 64 Ω typical on-resistance at ±5 V, < ±0.4 pC charge injection, and supports -40 °C to +125 °C operation in miniQFN-16 packaging.
For engineers reviewing the DG604EEQ-T1-GE3 datasheet, DG604EEQ-T1-GE3 pinout, DG604EEQ-T1-GE3 application, or DG604EEQ-T1-GE3 equivalent, key selection criteria include ultralow charge injection for high-accuracy sampling, guaranteed 2 V logic-high threshold at ±5 V, break-before-make switching, and compatibility with medical instrumentation and automated test equipment requiring low leakage and high isolation.
Technical Context
The DG604EEQ-T1-GE3 implements a 3-bit binary address decoder (A0, A1, ENABLE) to select one of four bidirectional analog inputs (S1–S4) to a common drain (D). Its CMOS architecture enables symmetrical conduction and rail-to-rail analog signal handling up to supply limits, with internal clamping diodes protecting against overvoltage transients.
It features break-before-make switching with 7 ns typical tBBM at room temperature, 414 MHz -3 dB bandwidth under ±5 V dual-supply conditions, and > -60 dB off-isolation and crosstalk at 10 MHz - critical for high-fidelity multiplexing in multi-channel sensor interfaces and precision ADC front ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Analog Signal Range | ±5 V (dual supply) or 0–5 V (single supply): supports full-rail input/output without clipping in standard industrial and medical voltage domains. |
| On-Resistance (RDS(on)) | 64 Ω typ. at ±5 V: ensures minimal gain error and channel-to-channel mismatch in precision gain-setting or signal routing paths. |
| Charge Injection | ±0.3 pC typ.: reduces sampling pedestal error in S/H circuits, enabling sub-16-bit accuracy without complex correction. |
| Off-Isolation (OIRR) | -67 dB typ. at 10 MHz: suppresses crosstalk between inactive channels, essential for simultaneous multi-signal integrity in dense analog systems. |
| Leakage Current | ±0.003 nA typ. at 25 °C (miniQFN): maintains DC accuracy in high-impedance sensor nodes and low-power battery-operated instruments. |
| Bandwidth | 414 MHz (-3 dB): preserves fast transient fidelity in wideband applications such as RF test instrumentation and high-speed data logging. |
| Logic Threshold | 2 V min. logic-high at ±5 V: ensures robust TTL/CMOS compatibility and noise margin in mixed-signal control environments. |
Pinout & Package
The DG604EEQ-T1-GE3 is housed in a 16-pin miniQFN package (1.8 mm × 2.6 mm, 0.4 mm pitch), optimized for space-constrained PCB layouts and thermal performance (θJA = 152 °C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | S1–S4 Source Inputs | Bidirectional analog inputs; each connects to D when selected; withstands voltages up to V+ or V− via internal clamping diodes. |
| 5 | GND | Ground reference for digital control logic and substrate bias; must be low-impedance to minimize switching noise coupling. |
| 6, 7, 8 | A0, A1, ENABLE | 3-bit address/control bus; ENABLE high activates decoding; all inputs tolerate 0.8 V / 2 V thresholds for 3 V or 5 V logic compatibility. |
| 9, 10, 11, 12 | NC | No-connect pins; electrically isolated and not bonded - must remain unconnected per datasheet to avoid parasitic coupling. |
| 13 | V− | Negative supply rail; sets lower analog voltage limit and powers internal level-shifting circuitry for dual-supply operation. |
| 14 | V+ | Positive supply rail; defines upper analog range and powers analog switch core; supports up to +16 V single-supply operation. |
| 15 | D | Common drain output; bidirectional path carrying selected Sx signal; exhibits 11 pF CD(on) for predictable AC loading in filter or buffer stages. |
| 16 | NC | No-connect; exposed copper thermal pad is not electrically connected - requires solder paste stencil design per Vishay's recommended footprint. |
Key Features
| Feature | Design Value |
|---|---|
| Ultralow charge injection | ±0.3 pC typ. enables < 0.001% sampling error in 16-bit+ data acquisition without external correction circuitry. |
| Break-before-make switching | 7 ns typical tBBM prevents momentary shorting between channels, eliminating signal glitches during reconfiguration. |
| Wide supply flexibility | Operates from 3 V single supply to ±8 V dual supply - simplifies system-level power architecture across portable and industrial platforms. |
| High-frequency isolation | -67 dB off-isolation at 10 MHz ensures > 60 dB dynamic range preservation when multiplexing RF or fast-slewing sensor signals. |
| Extended temperature range | Specified from -40 °C to +125 °C - qualified for under-hood automotive, industrial PLC, and downhole instrumentation use cases. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog multiplexer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617ESE+ | 16-pin SOIC; higher RDS(on) (100 Ω typ.); 10 pC charge injection; -40 °C to +85 °C only. | Limited to commercial-temperature industrial controls; unsuitable for extended-temp medical or automotive designs. | Select when board space allows SOIC and temperature range ≤ +85 °C suffices. |
| ADG1404YRUZ | 16-pin TSSOP; 4.7 Ω RDS(on); ±12 V supply; 0.25 pC charge injection; -40 °C to +125 °C. | Higher drive strength and wider voltage range, but larger package and higher cost. | Choose for ultra-low on-resistance needs in high-current analog routing where miniQFN size is secondary. |
Compared with MAX4617ESE+ and ADG1404YRUZ, the DG604EEQ-T1-GE3 uniquely balances ultralow charge injection, miniaturized QFN packaging, and full -40 °C to +125 °C qualification - making it optimal for space- and accuracy-critical embedded measurement systems where thermal robustness is non-negotiable.

FAQ
What supply voltage ranges does the DG604EEQ-T1-GE3 support?
The DG604EEQ-T1-GE3 supports single-supply operation from +3 V to +16 V and dual-supply operation from ±3 V to ±8 V. It is fully specified at +3 V, +5 V, and ±5 V, with guaranteed performance across the full -40 °C to +125 °C temperature range. The DG604EEQ-T1-GE3 maintains rail-to-rail analog signal handling within these supply constraints.
How does the DG604EEQ-T1-GE3 achieve ultralow charge injection?
The DG604EEQ-T1-GE3 achieves ±0.3 pC typical charge injection through proprietary CMOS process optimization and matched transistor geometry in its analog switch cells. This minimizes voltage transient errors on hold capacitors in sample-and-hold circuits. The DG604EEQ-T1-GE3's charge injection remains stable across the full analog input range and temperature extremes.
Is the DG604EEQ-T1-GE3 pin-compatible with other Vishay 4-channel multiplexers?
No - the DG604EEQ-T1-GE3 uses a 16-pin miniQFN package with specific pin assignments (e.g., V+, V−, GND, D, S1–S4, A0/A1/ENABLE, NCs) that differ from Vishay's TSSOP variants like DG604EEQ-T1-GE4. Layout redesign is required when migrating between packages. The DG604EEQ-T1-GE3's pinout is fixed per its miniQFN-16 outline and cannot be substituted without PCB revision.
What is the maximum signal frequency the DG604EEQ-T1-GE3 can handle without significant attenuation?
The DG604EEQ-T1-GE3 has a -3 dB bandwidth of 414 MHz under ±5 V dual-supply conditions with 50 Ω source/load and 5 pF capacitance. At 10 MHz, it provides > -60 dB off-isolation and < -65 dB crosstalk. For signals above 100 MHz, maintain controlled impedance traces and minimize parasitic capacitance to preserve the DG604EEQ-T1-GE3's high-frequency performance.
Does the DG604EEQ-T1-GE3 require external protection diodes for overvoltage events?
No - the DG604EEQ-T1-GE3 integrates internal clamping diodes on all analog terminals (S1–S4, D) to V+ and V−. Signals exceeding the supply rails are safely clamped, provided forward diode current remains within absolute maximum ratings (30 mA continuous, 100 mA pulsed). External diodes are unnecessary unless transient energy exceeds internal diode capability. Always verify clamp current in the DG604EEQ-T1-GE3's application context.
