Product details
Overview
DG2002EDL-T1-GE3 from Vishay Siliconix is a single-pole, double-throw (SPDT) analog switch optimized for 1.8 V to 5.5 V single-supply operation, featuring 6 Ω typical on-resistance at 5 V, 1 pC charge injection, and break-before-make switching. It serves as a bidirectional 2:1 multiplexer in signal routing paths of portable instrumentation and low-voltage data acquisition systems.
For engineers reviewing the DG2002EDL-T1-GE3 datasheet, DG2002EDL-T1-GE3 pinout, DG2002EDL-T1-GE3 application, or DG2002EDL-T1-GE3 equivalent, this page delivers verified specifications, SC-70-6 package details, power-off protection behavior, and validated alternative options for battery-powered and medical-grade analog signal switching.
Technical Context
The DG2002EDL-T1-GE3 uses high-density CMOS fabrication to achieve low RDS(on) flatness (0.4 Ω typ. at 5 V) and tight RDS(on) matching (0.04 Ω typ.), enabling precision signal routing without gain error across channels. Its control logic accepts inputs up to 5.5 V independent of V+, supporting mixed-voltage interface scenarios.
Integrated powered-off protection prevents current flow from COM to V+ during power-down, while 7 kV HBM ESD rating and latch-up immunity (>200 mA per JESD78) ensure robustness in handheld and clinical environments operating from –40 °C to +85 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 1.8 V to 5.5 V single supply - supports direct interfacing with 1.8 V, 2.5 V, 3.3 V, and 5 V logic and analog rails |
| On-Resistance (RDS(on)) | 6 Ω typ. at V+ = 5 V - minimizes voltage drop and signal attenuation in precision sensor or ADC front-end paths |
| Charge Injection | 1 pC typ. - reduces settling error and glitch amplitude in sample-and-hold or multiplexed ADC circuits |
| Off-Isolation (OIRR) | –78 dB at 1 MHz - suppresses crosstalk between NC/NO paths during channel switching in multi-channel systems |
| Switching Speeds | tON = 10 ns typ., tOFF = 8 ns typ. at 5 V - enables sub-50 ns channel selection for high-throughput data acquisition |
| Power-Down Leakage | 2 μA max. at V+ = 0 V - maintains safe isolation when host system is unpowered, critical for battery safety |
| ESD Rating (HBM) | 7000 V - meets IEC 61000-4-2 Level 4 for handling in production and field service of portable devices |
Pinout & Package
The DG2002EDL-T1-GE3 is housed in a compact, surface-mount SC-70-6 package (2.0 mm × 1.25 mm × 0.9 mm), optimized for space-constrained portable designs. Pin 1 is marked with "H9" on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (IN) | Digital control input | Active-high logic: "1" ≥ 2.4 V selects NO path; "0" ≤ 0.8 V selects NC path - compatible with 1.8 V to 5.5 V logic drivers |
| 2 (NO) | Normally open switch terminal | Connects to COM only when IN = high - used for primary signal path or default-off function |
| 3 (COM) | Common analog I/O node | Bidirectional port handling signals up to V+ amplitude - routes analog/digital signals in either direction without polarity restriction |
| 4 (GND) | Analog/digital ground reference | Single ground return for supply and logic - must be low-impedance to minimize noise coupling into analog paths |
| 5 (NC) | Normally closed switch terminal | Connects to COM only when IN = low - provides fail-safe or default-on routing capability |
| 6 (V+) | Positive supply rail | Supplies internal bias and switch driver - also defines analog signal range (0 V to V+) and logic threshold scaling |
Key Features
| Feature | Design Value |
|---|---|
| Powered-off protection | Prevents reverse current from COM to V+ during power-down - eliminates risk of backfeeding damaged power rails in battery-backed systems |
| Break-before-make switching | Guaranteed 1 ns minimum tBBM - avoids momentary shorting between NC and NO paths, essential for fault-tolerant signal routing |
| Low off-capacitance | 7 pF typ. at NC/NO - preserves high-frequency signal integrity and minimizes loading on source impedance in RF or fast-sampling applications |
| Wide logic input tolerance | Inputs tolerate up to 5.5 V regardless of V+ - enables direct connection to higher-voltage microcontrollers without level-shifting |
| High ESD robustness | 7000 V HBM / 1000 V CDM - sustains repeated handling and board-level transients in consumer and medical assembly lines |

Equivalent & Alternatives
The following parts are listed as comparable options for similar SPDT analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Texas Instruments TS5A23157DBVR | 5.5 V max supply; 0.9 Ω RDS(on) at 3.3 V; no powered-off protection circuit | Lacks COM-to-V+ blocking during power-down - unsuitable where battery isolation is required | Preferred for ultra-low on-resistance in always-powered systems; requires external protection if V+ can be absent |
| Analog Devices ADG821BRMZ | 1.8 V to 5.5 V; 0.5 Ω RDS(on) at 3 V; 125 °C max operating temperature | Higher cost and larger MSOP-8 package - less optimal for ultra-compact portable layouts | Chosen when extended temperature range or lower on-resistance justifies footprint and BOM cost increase |
Compared with TS5A23157DBVR and ADG821BRMZ, the DG2002EDL-T1-GE3 uniquely combines SC-70-6 miniaturization, guaranteed powered-off protection, and 6 Ω on-resistance at 5 V - making it the optimal choice for space- and safety-critical battery-powered instrumentation.

FAQ
What is the maximum analog signal voltage supported by the DG2002EDL-T1-GE3?
The DG2002EDL-T1-GE3 supports analog signals from 0 V to V+, meaning its maximum analog voltage equals the applied V+ supply. At V+ = 5.5 V, the full analog range is 0 V to 5.5 V - bidirectionally - with no clamping or degradation, as confirmed in the Absolute Maximum Ratings and Signal Range specifications.
Does the DG2002EDL-T1-GE3 require external pull-up or pull-down resistors on the IN pin?
No. The DG2002EDL-T1-GE3 has CMOS-compatible logic thresholds (VINL ≤ 0.8 V, VINH ≥ 2.4 V at V+ = 5 V) and draws only ±1 μA input current. Direct connection to microcontroller GPIO or FPGA outputs is sufficient; external biasing resistors are unnecessary unless noise immunity in high-EMI environments is required.
How does powered-off protection work in the DG2002EDL-T1-GE3?
When V+ = 0 V, the DG2002EDL-T1-GE3 internally disables conduction paths from COM to V+, limiting power-down leakage to ≤2 μA. This prevents reverse current flow that could damage upstream power sources - a critical feature for battery-backed systems where COM may remain biased while V+ is removed.
Can the DG2002EDL-T1-GE3 operate reliably at 1.8 V supply with full specification compliance?
Yes. The DG2002EDL-T1-GE3 is fully specified down to 1.8 V: RDS(on) = 37 Ω max, tON/tOFF ≤ 42 ns, and logic thresholds scale to VINL ≤ 0.4 V / VINH ≥ 1.6 V. All parameters - including leakage, charge injection (0.8 pC), and off-isolation (–78 dB) - are guaranteed across –40 °C to +85 °C at 1.8 V.
What is the thermal resistance (θJA) of the DG2002EDL-T1-GE3 in SC-70-6 package?
The DG2002EDL-T1-GE3 datasheet specifies a power dissipation limit of 250 mW for the SC-70-6 package, with derating of 3.1 mW/°C above 70 °C. While θJA is not explicitly listed, the derating slope implies θJA ≈ 323 °C/W - consistent with industry-standard SC-70 thermal performance under typical PCB copper area conditions.
