Vishay Siliconix
2 Port, USB 2.0 High Speed (480 Mbps) Switch,
DPDT Analog Switch
DESCRIPTION
FEATURES
The DG2720 is 2 Port high speed analog switch optimized
for USB 2.0 signal switching. The DG2720 switch is
configured in DPDT. It handles bidirectional signal flow,
achieving a 620 MHz -3 dB bandwidth with 5 pF load, and a
port to port Crosstalk and isolation at -49 dB.
• Wide operation voltage range
Processed with high density sub micron CMOS, the
DG2720 provide low parasitic capacitance. Signals are
routed with minimized phase distortion and attain a bit to bit
skew is as low as 40 pS.
The DG2720 is designed for a wide range of operating
voltages, from 2.7 V to 4.3 V that can be driven directly from
one cell Li-ion battery. On-chip circuitry protects against
conditions when either the D+/D- lines are shorted to the
VBUS at the USB port. Additionally, logic control pins (S and
OE) can tolerate the presence of voltages that are above the
supply power rail (V+). The control logic threshold is
guaranteed to be (VIH = 1.3 V/min).
Latch up current is greater than 300 mA, as per JESD78, and
its ESD tolerance exceeds 8 kV.
Packaged in ultra small miniQFN-10 (1.4 mm x 1.8 mm x
0.55 mm), it is ideal for portable high speed mix signal
switching application.
As a committed partner to the community and the
environment, Vishay Siliconix manufactures this product
with lead (Pb)-free device termination. The miniQFN-10
package has a nickel-palladium-gold device termination
and is represented by the lead (Pb)-free “-E4” suffix to the
ordering part number. The nickel-palladium-gold device
terminations meet all JEDEC® standards for reflow and MSL
rating.
• Low on-resistance, 5.7 Ω (typical at 3 V)
• Low capacitance, 5.6 pF (typical)
• 3 dB high bandwidth with 5 pF load:
620 MHz (typical)
• Low bit to bit skew: 40 pS (typical)
• Low power consumption
• Low logic threshold: V
• Power down protection: D+/D- pins can tolerate up to 5 V
when V+ = 0 V
• Logic (S and OE) above V+ tolerance
• Latch-up current greater than 300 mA per JESD78
• 8 kV ESD protection (HBM)
• Lead (Pb)-free low profile miniQFN-10 (1.4 mm x 1.8 mm
x 0.55 mm)
• Material categorization: for definitions of compliance
please see www.vishay.com/doc?99912
APPLICATIONS
• Cellular phones
• Portable media players
• PDA
• Digital camera
• GPS
• Notebook computer
• TV, monitor, and set top box
As a further sign of Vishay Siliconix's commitment, the
DG2720 is fully RoHS complaint.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
