Product details
Overview
DG2020DV-T1-E3 from Vishay Siliconix is a low-voltage single-pole/double-throw (SPDT) CMOS analog switch optimized for high-performance signal routing in portable systems. It features 0.8 Ω NO on-resistance at 5 V, guaranteed break-before-make switching, and operates from 2.7 V to 5.5 V - enabling precision analog path selection in battery-powered cellular phones and test equipment.
For engineers reviewing the DG2020DV-T1-E3 datasheet, DG2020DV-T1-E3 pinout, DG2020DV-T1-E3 application, or DG2020DV-T1-E3 equivalent, key selection criteria include on-resistance matching between NC/NO paths, charge injection (<5 pC), off-isolation (–53 dB at 1 MHz), and TSOP-6 package compatibility with space-constrained PCB layouts.
Technical Context
The DG2020DV-T1-E3 implements a monolithic CMOS SPDT architecture with independent NC and NO channel control via a single digital input. Its JI2 low-voltage process ensures latchup immunity and symmetric bidirectional conduction when on, while internal clamping diodes protect terminals against overvoltage up to V+ + 0.3 V.
Break-before-make timing is guaranteed (td ≤ 1.5 μs at full temperature range), and dynamic performance is characterized across supply voltages: tON(NO) = 3–6 μs and tOFF(NC) = 1–3.5 μs at V+ = 5 V with 300 Ω/35 pF load - supporting reliable signal switching in audio and sensor multiplexing applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct interface with 3.3 V and 5 V logic domains without level shifting |
| RON(NO) @ V+ = 5 V | 0.9 Ω max - enables <10 mV voltage drop at 100 mA, critical for low-distortion analog signal paths |
| RON(NC) @ V+ = 5 V | 1.3 Ω max - maintains matched on-resistance asymmetry <1.8×, reducing gain error in differential switching |
| Off-Isolation @ 1 MHz | –53 dB - suppresses crosstalk between inactive channels in multi-signal routing applications |
| Charge Injection | 5 pC max - limits transient glitches during switching, essential for precision ADC front-end multiplexing |
| Leakage Current @ 85 °C | ±98 nA - ensures minimal DC error accumulation in high-impedance sensor interfaces |
| Switching Time (tON/tOFF) | 2–6.5 μs - compatible with audio-band and medium-speed data acquisition sampling rates |
Pinout & Package
TSOP-6 surface-mount package (JEDEC MO-193C), 3.05 mm × 2.85 mm × 1.0 mm body, 0.95 mm pitch, lead-free and RoHS-compliant. Device marking: E3xxx.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - NO | Normally Open terminal | Connects to COM only when IN = HIGH; used for active-path signal routing |
| 2 - COM | Common analog port | Central bidirectional I/O node; carries signal to either NO or NC based on logic state |
| 3 - NC | Normally Closed terminal | Connects to COM only when IN = LOW; provides default signal path in fail-safe configurations |
| 4 - IN | Digital control input | TTL/CMOS-compatible logic input (VINH ≥ 2.4 V, VINL ≤ 0.8 V at V+ = 5 V) |
| 5 - V+ | Positive supply rail | Power source for internal switch circuitry; also defines analog signal range (0 to V+) |
| 6 - GND | Ground reference | Analog and digital ground return; must be low-impedance to minimize noise coupling |
Key Features
| Feature | Design Value |
|---|---|
| Asymmetrical SPDT topology | Enables distinct NC/NO path assignment for redundant or dual-function signal routing (e.g., primary/backup sensor inputs) |
| Guaranteed break-before-make | Eliminates momentary short-circuit between NC and NO paths, preventing signal contention in shared-bus systems |
| Low 0.2 μA supply current | Reduces quiescent power draw in always-on monitoring circuits, extending battery life in portable instrumentation |
| Epitaxial latchup protection | Ensures robust operation under transient overvoltage or ESD events without destructive latchup failure |
| Clamped I/O terminals | Internal diodes limit NC/NO/COM voltage excursions to V+ + 0.3 V, simplifying external surge protection design |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4617EUT+T | Higher RON (1.5 Ω NO), wider V+ range (2.7–12 V), no guaranteed break-before-make | Better suited for higher-voltage industrial sensors but lacks timing safety for shared-bus audio routing | Select when supply flexibility > timing guarantee; not recommended for fail-safe NC/NO path separation |
| ADG721BRMZ-REEL | Lower RON (0.6 Ω), same TSOP-6 package, but NC/NO paths are symmetrical (not asymmetrical) | Optimized for balanced dual-path applications (e.g., differential ADC inputs), not primary/backup routing | Choose for lowest on-resistance where path symmetry is required; DG2020DV-T1-E3 preferred for dedicated NC/NO functional distinction |
Compared with MAX4617EUT+T and ADG721BRMZ-REEL, the DG2020DV-T1-E3 uniquely combines guaranteed break-before-make timing, asymmetrical NC/NO on-resistance grading, and sub-1 Ω NO resistance in TSOP-6 - making it the optimal choice for safety-critical or functionally differentiated analog path selection.

FAQ
What is the maximum analog signal voltage range supported by the DG2020DV-T1-E3?
The DG2020DV-T1-E3 supports analog signals from 0 V to V+, where V+ ranges from 2.7 V to 5.5 V. Signals on NC, NO, or COM exceeding V+ are clamped by internal diodes - limiting absolute maximum analog voltage to V+ + 0.3 V per Absolute Maximum Ratings. This ensures safe operation with common 3.3 V and 5 V supply rails without external clamping components.
Does the DG2020DV-T1-E3 support bidirectional signal flow?
Yes, the DG2020DV-T1-E3 conducts equally well in both directions when ON, as confirmed in its functional description and truth table. The COM terminal serves as the central bidirectional node, while NO and NC operate as interchangeable signal paths depending on the IN logic state - making DG2020DV-T1-E3 suitable for AC-coupled audio, sensor, and data lines where polarity independence is required.
What is the guaranteed break-before-make time for the DG2020DV-T1-E3?
The DG2020DV-T1-E3 guarantees a break-before-make interval (td) of ≤1.5 μs across the full operating temperature range (–40 °C to +85 °C) at V+ = 5 V, as specified in the Dynamic Characteristics table. This timing prevents momentary shorting between NC and NO paths during state transitions - a critical requirement for avoiding signal corruption in shared-bus or fail-safe analog routing applications using DG2020DV-T1-E3.
How does the on-resistance of DG2020DV-T1-E3 vary with analog signal voltage?
DG2020DV-T1-E3 exhibits RON flatness of ≤0.13 Ω (NO) and ≤0.25 Ω (NC) over the full 0 V to V+ analog range at V+ = 4.5 V, per the RON Flatness specification. This minimal variation ensures consistent gain and linearity across the signal swing - especially important in precision instrumentation and audio applications where harmonic distortion must remain below –90 dB.
Is the DG2020DV-T1-E3 RoHS-compliant and lead-free?
Yes, the DG2020DV-T1-E3 is RoHS-compliant and lead-free, as confirmed by Vishay's packaging documentation (Document Number 71200) and land pattern specifications dated 2022. The TSOP-6 package uses matte tin lead finish, and the device marking "E3" denotes lead-free, halogen-free, and RoHS-compliant construction - meeting IPC/JEDEC J-STD-609A Class 1 requirements.
