Product details
Overview
DG2720DN-T1-E4 from Vishay Siliconix is a 2-port, DPDT analog switch optimized for USB 2.0 high-speed (480 Mbps) signal routing in portable electronics. It delivers 620 MHz -3 dB bandwidth with 5 pF load, 5.7 Ω typical on-resistance at 3 V, and -49 dB crosstalk, enabling bidirectional D+/D- switching between two high-speed data paths.
For engineers reviewing the DG2720DN-T1-E4 datasheet, DG2720DN-T1-E4 pinout, DG2720DN-T1-E4 application, or DG2720DN-T1-E4 equivalent, key selection criteria include its miniQFN-10 package footprint, 40 ps typical bit-to-bit skew, ±250 mA continuous current rating on data pins, and 8 kV HBM ESD protection-critical for USB port interface robustness in space-constrained designs.
Technical Context
The DG2720DN-T1-E4 implements a CMOS-based DPDT switch architecture with break-before-make timing (5 ns typical) and integrated power-down protection that allows D+/D- pins to tolerate up to 5 V when V+ = 0 V. Its logic control inputs (S and OE) support overvoltage tolerance above V+, with guaranteed VIH ≥ 1.3 V at 3–3.6 V supply.
Signal integrity is maintained via low parasitic capacitance (5.6 pF typical input capacitance), matched on-resistance (0.35 Ω typical match), and minimized phase distortion across the 480 Mbps USB 2.0 eye diagram-validated by pass-level compliance testing including <68.2 ps consecutive jitter and 26.8 ps RMS jitter at 480.0009 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (-3 dB) | 620 MHz with 5 pF load - supports full USB 2.0 high-speed signaling without attenuation |
| On-resistance (RDS(on)) | 5.7 Ω typical at 3 V - minimizes voltage drop and signal loss across D+/D- paths |
| Crosstalk | -49 dB - ensures isolation between active and inactive USB channels during switching |
| Bit-to-bit skew | 40 ps typical - preserves differential timing alignment critical for USB 2.0 eye opening |
| ESD protection (HBM) | 8 kV - protects D+/D- lines against common handling and system-level electrostatic discharge |
| Supply range | 2.7 V to 4.3 V - enables direct operation from single-cell Li-ion battery without regulation |
| Logic threshold (VIH) | 1.3 V min at 3–3.6 V V+ - ensures reliable control from low-voltage GPIOs |
Pinout & Package
Packaged in ultra-small miniQFN-10 (1.4 mm × 1.8 mm × 0.55 mm) with nickel-palladium-gold lead-free terminations (E4 suffix), the DG2720DN-T1-E4 supports high-density PCB layouts and JEDEC-compliant reflow profiles (MSL 1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 7, 9 | HSD1±, HSD2± | High-speed differential channel pairs - connect to upstream/downstream USB ports |
| 3, 4 | D± | Common USB 2.0 D+/D- I/O - interfaces directly to host/device PHY |
| 5 | GND | Analog/digital reference ground - requires low-inductance connection to minimize noise coupling |
| 6 | V+ | Positive supply rail - powers internal switch core and level-shifted logic |
| 8 | OE | Enable/disable control - high = disconnect; low = active switching path |
| 10 | S | Port select input - selects HSD1± (S=0) or HSD2± (S=1) as active path |
Key Features
| Feature | Design Value |
|---|---|
| USB 2.0 compliant signal integrity | Passes high-speed eye diagram test per USB-IF spec at 480 Mbps with <26.8 ps RMS jitter |
| Overvoltage-tolerant logic inputs | S and OE pins withstand voltages > V+, eliminating need for external level shifters |
| Power-down protection | D+/D- pins survive 5 V fault condition even when V+ = 0 V - prevents damage during hot-plug events |
| Low on-capacitance matching | Channel-on capacitance of 11 pF and off-capacitance of 4 pF - maintains impedance continuity across switch states |
| Latch-up immunity | ≥300 mA per JESD78 - ensures robust operation under transient overcurrent conditions |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 analog switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TS3USB30E | Single-pole double-throw (SPDT); 5.5 Ω RDS(on); 650 MHz bandwidth; 6-pin UQFN | Supports only one USB path vs. DG2720DN-T1-E4's DPDT configuration | Choose for simpler single-path routing where dual-port selection is unnecessary |
| FSUSB30 | DPDT; 6.5 Ω RDS(on); 500 MHz bandwidth; -45 dB crosstalk; 10-pin UMLP | Lower bandwidth and higher crosstalk than DG2720DN-T1-E4; no V+ = 0 V D+/D- tolerance | Acceptable where 500 MHz bandwidth suffices and power-down protection is not required |
Compared with TS3USB30E and FSUSB30, the DG2720DN-T1-E4 provides superior USB 2.0 signal fidelity (620 MHz bandwidth, -49 dB crosstalk, 40 ps skew) and unique fault resilience (5 V D+/D- tolerance at V+ = 0 V), making it optimal for dual-port, high-reliability portable USB switching.

What is the maximum operating voltage for DG2720DN-T1-E4?
The DG2720DN-T1-E4 operates from 2.7 V to 4.3 V, allowing direct connection to single-cell Li-ion batteries. Absolute maximum ratings permit V+ up to +5 V, but functional operation is specified only within the 2.7–4.3 V range. Exceeding 4.3 V may impact RDS(on) stability and timing parameters.
Does DG2720DN-T1-E4 support USB 2.0 high-speed (480 Mbps) compliance?
Yes, the DG2720DN-T1-E4 passes USB-IF high-speed signal quality tests, including eye diagram validation at 480.0009 MHz with measured RMS jitter of 26.8 ps and consecutive jitter within ±68.2 ps. Its 620 MHz -3 dB bandwidth and 40 ps bit-to-bit skew meet USB 2.0 physical layer requirements.
How does the power-down protection feature work on DG2720DN-T1-E4?
When V+ = 0 V, the DG2720DN-T1-E4's D+/D- pins tolerate up to 5 V - protecting against hot-plug events or VBUS leakage. This is implemented via internal clamping structures, distinct from standard ESD diodes. The feature is validated per datasheet test conditions and does not require external components.
What is the pin configuration of DG2720DN-T1-E4 and how is Pin 1 identified?
The DG2720DN-T1-E4 uses a miniQFN-10 package with Pin 1 located at the top-left corner (long lead side) when viewing the top marking "Gx". Pinout includes D± (pins 3–4), GND (pin 5), V+ (pin 6), OE (pin 8), S (pin 10), and HSD1±/HSD2± (pins 1–2, 7, 9). Full layout details are in Vishay document 74496.
Is DG2720DN-T1-E4 RoHS and lead-free compliant?
Yes, DG2720DN-T1-E4 is fully RoHS compliant and features lead (Pb)-free nickel-palladium-gold terminations, indicated by the "-E4" suffix. It meets JEDEC standards for reflow soldering and MSL Level 1 classification, with no exemptions required under Directive 2011/65/EU.
