DG2722  
Vishay Siliconix  
2 Port, USB 2.0 High Speed (480 Mbps) Switch,  
DPDT Analog Switch  
FEATURES  
DESCRIPTION  
•
Halogen-free according to IEC 61249-2-21  
Definition  
The DG2722 is 2 port high speed analog switch optimized for  
USB 2.0 signal switching. The DG2722 switch is configured  
in DPDT. It handles bidirectional signal flow, achieving a  
900 MHz - 3 dB bandwidth, and a port to port crosstalk and  
isolation at - 49 dB.  
Processed with high density sub micron CMOS, the DG2722  
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 DG2722 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  
300 mA, as per JESD78, and its ESD tolerance exceeds  
8 kV.

Lead (Pb)-free low profile miniQFN-10 (1.4 mm x 1.8 mm  
x 0.55 mm)  
•
Compliant to RoHS Directive 2002/95/EC  
APPLICATIONS  
• Cellular phones  
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.  
As a further sign of Vishay Siliconix's commitment, the  
DG2722 is fully RoHS complaint.
