Product details
Overview
DG2730DN-T1-GE4 from Vishay Siliconix is a DPDT analog switch optimized for USB 2.0 high-speed (480 Mbps) signal routing in portable electronics. It operates from 2.7 V to 5.5 V, delivers 5.5 Ω typical on-resistance at 3 V, 900 MHz −3 dB bandwidth, and −36 dB crosstalk at 240 MHz - enabling low-distortion bidirectional data switching in compact mobile designs.
For engineers reviewing the DG2730DN-T1-GE4 datasheet, DG2730DN-T1-GE4 pinout, DG2730DN-T1-GE4 application, or DG2730DN-T1-GE4 equivalent, key selection criteria include its miniQFN-10 footprint, 40 ps typical bit-to-bit skew, 5.5 kV HBM ESD rating, power-down protection on D±/HSD± pins, and guaranteed VIH threshold down to 1.3 V at V+ ≤ 3.6 V.
Technical Context
The DG2730DN-T1-GE4 implements a single DPDT (double-pole, double-throw) analog switch architecture using high-density sub-micron CMOS. Its control logic accepts OE (enable) and S (select) inputs with overvoltage-tolerant inputs up to V+ + 0.3 V, supporting direct interfacing with 1.8 V logic even when powered from 3.3 V.
It features break-before-make switching (5 ns typical), 3 pC typical charge injection, and maintains <2 ps channel-to-channel skew across temperature. Off-isolation of −29 dB and crosstalk of −36 dB are measured at 240 MHz with 50 Ω terminations and 5 pF load, confirming suitability for full-speed USB signal integrity requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7 V to 5.5 V - supports direct operation from single-cell Li-ion (3.0–4.2 V) or 5 V rail without level-shifting. |
| On-Resistance (RDS(on)) | 5.5 Ω typical at 3 V - ensures minimal insertion loss and voltage drop for USB D+/D− signals under 8 mA drive. |
| −3 dB Bandwidth | 900 MHz typical - preserves signal integrity for USB 2.0 high-speed (480 Mbps) eye diagrams with <1% amplitude loss. |
| Crosstalk | −36 dB at 240 MHz - prevents coupling between active and inactive USB channels during port switching. |
| Off-Isolation | −29 dB at 240 MHz - suppresses signal leakage from disconnected HSD1/HSD2 ports into active D+ or D− path. |
| Bit-to-Bit Skew | 40 ps typical - maintains tight timing alignment between D+ and D− transitions to avoid USB packet jitter. |
| ESD Rating (HBM) | 5.5 kV - protects D+, D−, HSD1±, and HSD2± pins against electrostatic discharge during board handling and connector mating. |
Pinout & Package
Packaged in ultra-small miniQFN-10 (1.4 mm × 1.8 mm × 0.55 mm) with nickel-palladium-gold (NiPdAu) lead-free terminations, the DG2730DN-T1-GE4 supports high-density PCB layouts and JEDEC-compliant reflow profiles (MSL 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GND (Pin 1) | Ground reference | Primary return path for analog and digital currents; must be low-impedance connection to system ground plane. |
| V+ (Pin 2) | Positive supply | Single power rail input (2.7–5.5 V); powers internal switch array and control logic. |
| S (Pin 3) | Select input | Binary control: logic high routes D± to HSD1±, logic low routes D± to HSD2± (OE = low). |
| HSD2− (Pin 4) | High-speed data port 2, negative | USB differential pair endpoint for second downstream device; tolerates 5.5 V when V+ = 0 V. |
| OE (Pin 5) | Output enable | Active-low global enable: OE = high disconnects all paths; OE = low enables S-controlled routing. |
| HSD2+ (Pin 6) | High-speed data port 2, positive | Complementary endpoint to HSD2−; matched trace length required for USB differential impedance (90 Ω). |
| D− (Pin 7) | USB host/device D− line | Common analog signal path; bidirectional; connects to upstream USB controller or connector. |
| HSD1− (Pin 8) | High-speed data port 1, negative | First alternate USB endpoint; shares same electrical specs and protection as HSD2±. |
| D+ (Pin 9) | USB host/device D+ line | Complementary to D−; routed identically through switch; requires identical layout symmetry. |
| HSD1+ (Pin 10) | High-speed data port 1, positive | Complementary endpoint to HSD1−; enables dual-port USB device sharing without external multiplexing. |
Key Features
| Feature | Design Value |
|---|---|
| DPDT USB 2.0 Switch Architecture | Enables seamless switching between two USB peripheral ports using only two control lines (S and OE), eliminating need for discrete mux ICs or FPGA I/O. |
| Power-Down Protection | D+, D−, HSD1±, and HSD2± pins withstand 5.5 V when V+ = 0 V - prevents latch-up or damage during hot-plug or battery removal scenarios. |
| Low On-Capacitance (5.8 pF) | Minimizes loading on high-speed USB traces, preserving signal rise/fall times and reducing reflections at 480 Mbps data rates. |
| Overvoltage-Tolerant Control Inputs | S and OE accept logic high up to V+ + 0.3 V - allows direct interface with 1.8 V or 2.5 V GPIO without external level shifters. |
| Guaranteed VIH Threshold | VIH = 1.3 V minimum at V+ ≤ 3.6 V - ensures reliable switching with weak-drive microcontrollers or battery-voltage-sensitive systems. |

Use Value: Achieves −29 dB off-isolation to suppress noise coupling from DP signaling into USB data paths, critical for error-free enumeration. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar DPDT USB 2.0 analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSUM3210A | Higher RDS(on) (8 Ω typ.), lower bandwidth (600 MHz), no overvoltage-tolerant controls. | Limited to fixed 3.3 V systems; lacks power-down protection on data pins. | Acceptable for cost-sensitive, non-hot-plug USB hubs where V+ is stable and ESD risk is low. |
| MAX4989ETE+ | Wider supply range (1.8–5.5 V), but larger 16-pin TQFN package and higher CON (9.5 pF). | Better for mixed-voltage systems with 1.8 V logic, but less suitable for ultra-thin mobile PCBs due to size and capacitance. | Preferred when interfacing with 1.8 V controllers without level shifters, provided board space allows larger footprint. |
Compared with TSUM3210A and MAX4989ETE+, the DG2730DN-T1-GE4 offers superior USB 2.0 signal fidelity (900 MHz BW, 40 ps skew), smallest form factor (miniQFN-10), and integrated power-down protection - making it optimal for space-constrained, battery-powered USB switching where reliability and hot-plug safety are critical.

FAQ
What is the maximum operating frequency supported by the DG2730DN-T1-GE4 for USB 2.0 signals?
The DG2730DN-T1-GE4 supports USB 2.0 high-speed operation up to 480 Mbps, validated by its 900 MHz −3 dB bandwidth and −36 dB crosstalk at 240 MHz. This ensures full compliance with USB 2.0 eye diagram specifications, including rise/fall time preservation and jitter control. The DG2730DN-T1-GE4 maintains signal integrity across the entire frequency spectrum required for reliable packet transmission without equalization.
Does the DG2730DN-T1-GE4 support power-down protection when the supply is off?
Yes, the DG2730DN-T1-GE4 provides robust power-down protection: D+, D−, HSD1±, and HSD2± pins tolerate up to 5.5 V even when V+ = 0 V. This prevents back-powering, latch-up, or ESD-induced damage during hot-plug events or battery removal. The DG2730DN-T1-GE4 achieves this via integrated clamping structures, confirmed per absolute maximum ratings in the Vishay datasheet (Document #67786).
Can the DG2730DN-T1-GE4 be controlled directly by a 1.8 V microcontroller?
Yes - the DG2730DN-T1-GE4 control pins S and OE are overvoltage-tolerant up to V+ + 0.3 V and guarantee VIH ≥ 1.3 V when V+ ≤ 3.6 V. When powered from 3.3 V, a 1.8 V logic high meets the input threshold margin safely. The DG2730DN-T1-GE4 thus eliminates external level shifters in mixed-voltage portable systems, simplifying design and reducing BOM count.
What is the thermal performance of the DG2730DN-T1-GE4 in miniQFN-10 package?
The DG2730DN-T1-GE4 in miniQFN-10 has a power dissipation rating of 208 mW at +70 °C, derating linearly by 2.6 mW/°C above that temperature. Its thermal resistance (θJA) is optimized for PCBs with standard thermal vias under the exposed pad. The DG2730DN-T1-GE4 operates reliably from −40 °C to +85 °C ambient, with on-resistance variation tightly characterized across this range per the datasheet RON vs. temperature curves.
How does the DG2730DN-T1-GE4 handle USB signal skew between D+ and D−?
The DG2730DN-T1-GE4 achieves 40 ps typical bit-to-bit skew and 50 ps maximum channel-to-channel skew, ensuring D+ and D− edges remain tightly aligned to preserve USB 2.0 differential timing margins. This performance is enabled by matched internal switch paths and low parasitic capacitance (5.8 pF). The DG2730DN-T1-GE4's skew specification directly supports USB 2.0 eye opening requirements without external deskew circuitry.
